Old Trackers on eBay and Winterhighland

The original digital beacon, the Tracker DTS

Tracker DTS 2nd edition
The ubiquitous Tracker 1. Still on sale, often advertised second hand on eBay, Winterhighland and other sources such as social media.  Probably the most common transceiver carried for many years as the first digital transceiver, and a huge improvement on analog. It's quite fast, but it only has two antenna's.

I tell my students/customers to get an upgrade to 3 antennas which is better by far, especially when getting close to the victim as unlike the 2 antenna transceivers there are no "null points" or signal spikes.  I see lots of second hand T1's getting sold off. The newer version T1 is still probably ok but the original version is so old that I certainly would be very wary of buying one (I personally wouldn't) unless I checked its battery terminals, and range checked it on both send and receive to a modern beacon to see if it has frequency drift and maintains power. You could be fine with a newer one, but better to put the money into a new model such as a Tracker 2 or even 3 in my opinion, or one with a mark feature. Which is probably what the seller of a second hand one is doing with the money you give them. Sellers would be better keeping the old ones to bury and practice searching for. To put reliability in context I have lost a few old transceivers that stopped transmitting in the snow on recovery scenarios. You get what you pay for second hand.

Students on my training days like the speed, simplicity and clear display and mark feature of the Ortovox 3+. Default auto revert is ON (BCA trackers it's OFF).  This would be my beacon of choice as value for money for most folk, with the right balance of speed, ease of use and simple but reliable features which include smart antenna orientation and the built in Recco strip so the victim is more searchable by the Recco system in organised rescue. So save you pennies and get a new transceiver.

Avalanche Safety Gear Winter 18/19 Prices

Ascent 22 with a carbon cartridge. Very light and perfect for Ski Patrol or Scottish off piste and day tours
The average depth of a buried skier is 1.5 meters. You need a good shovel and a structured method to remove the snow fast and get the victim's airway cleared. Time to dig is "Triple H" the killer triad of Hypoxia, Hypercapnia (re breathing your own Co2) and Hypothermia.

Winter around the corner and a very successful back country gathering in Edinburgh will have stoked folks up for getting out among the mountains next snowfall. Below is a price list for avalanche safety equipment that I sell. While I also retail ARVA and BCA stuff I tend to mainly sell Ortovox these days. This is for a number of reasons.

Ortovox do a full range of kit that I retail. From high quality outerwear to base layers. All well thought out and working as a layering system. It's also pretty gucci! Ortovox run a safety academy and education package which allows retailers to offer a bit more than just sales. For example if you buy a beacon from me I offer an hours free training at a beacon training park. Ortovox have a long history of manufacturing avalanche beacons. Their kit is extremely high quality and reliable and meets the practical function and design requirements of professionals working in the mountains. Avalanche safety kit must never fail, and so this quality and well thought out design makes Ortovox the best in the market in my opinion. While this post is about avalanche kit I can also quote you for clothing.

Prices indicated do not include P&P. If you are local I often meet up with folk in the ski areas or can get stuff to you or if you cover the postage I can send it. Ask for a quote if you want a bigger order and I can see what i can do.

Pro Alu III shovel. This also converts to a hoe which is really important when using the conveyor method to dig a victim out quickly as it speeds things up clearing behind the diggers on point

This is the best beacon for pro use with its advanced multiple and deep burial modes and a visual "game" level display of each victim. Unlike most 3 antenna beacons it calculates a direct line to the victim. Very clever!

320 PFA Probe. As a pro user perhaps also working with Winter ML groups you need a longer probe for picking snow hole sites and also a longer one for the deep burials common to buried mountaineers in terrain traps

Avalanches, Beacons and Being Searchable

1. Learn How to Interpret the Avalanche Forecast. Don't get avalanched ......

The Avalanche Danger Scale uses five progressively increasing danger levels: Low, Moderate, Considerable,  High and Extreme. It indicates the likelihood of avalanches, how they might be triggered and recommended actions in the back country. However, the wording is very brief and does not include a meaningful indication of risk. Below is an explanation of each danger level, including the transitions between levels, signs of instability at each level and the implications of slope angle, aspect and elevation.
Understanding the SAIS forecast as acting on it could save your life
Travel is generally safe. The snow pack is well bonded and natural avalanches will not be seen except for small sluffs on extremely steep slopes. Human-triggered avalanches are unlikely except in isolated locations in extreme terrain. The danger will usually be from wind-driven snow in gullies and chutes or deposited across very steep open slopes near ridge lines. Ski or board one by one as smoothly as possible without falling if you suspect the formation of wind slab. Be aware of shaded, north to east aspects where the danger may be transitioning to Moderate. There are few fatalities at this danger level.

This is the most difficult danger level for back country skiers and boarders to assess snow stability. Many of the usual indicators such as cracks, settling, whumpfing and signs of recent avalanche are absent, especially at the lower end of the moderate level. Key indicators are any recent snowfall, and wind deposition. Snow pack tests may help assess stability.

Conditions are generally favourable for travel providing routes are chosen carefully. The snow  pack is only moderately bonded on some steep slopes. Areas of danger are usually restricted to certain types of terrain such as bowls and gullies. The altitude, aspect and type of terrain where danger can be expected are usually detailed in the Avalanche Forecast. Remote triggering is unlikely, so you only need to be concerned about the steepness of nearby terrain features.

Human-triggered avalanches are possible. Ski or board carefully, one by one, in suspect terrain and avoid high loading of the snow pack by spreading people out on the uphill track. Carefully evaluate the stability of very steep slopes (steeper than 35°) and aspects identified as potentially dangerous in the Avalanche Forecast.

Be especially careful if the higher elevation band in the forecast, or the danger on other aspects, is Considerable. There is a significant difference in instability between Moderate and Considerable. Don’t get sucked onto higher, steeper and more dangerous slopes. Although naturally triggered avalanches are not expected, ice climbers should watch out for the sun warming steep collection zones above their climbs. If deep-slab instability due to a persistent weak layer is mentioned in the Avalanche Forecast, you need to pay careful attention to the terrain. Avalanches from such a layer are not only likely to be large and extensive, they are completely unpredictable. Unless you have specific local knowledge, keep off large open slopes at this danger level if the forecast warns of a persistent weak layer.

Conditions have become much less favourable. The snow pack is only moderately or poorly bonded over a much larger area of the terrain. Human triggering is possible by a single skier on steep slopes and aspects mentioned in the Avalanche Forecast. Remote triggering of avalanches is possible, so the maximum steepness of the slope above you should be used when deciding if you want to continue.

Instability indicators mentioned in Moderate danger above will likely be present. Back country touring at this danger level requires good route finding skills, and experience in recognising dangerous terrain and evaluating slope stability. Keep to slopes of less than 35°, especially slopes at the altitude and aspect indicated in the Avalanche Forecast. Remember that remote triggering is possible. Typically the scree fans at the bottom of gullies start out at around 30° and the slope steepens as it gets higher. Keep off such slopes at this hazard level. The remarks about persistent weak layers in the previous section on Moderate danger level also apply to this danger level.
New SAIS graphic as stripes for localised "considerable"

Reports such as the above showing stripes as areas of  localised "considerable" risk  to North and South within a moderate NW to SW aspect and considerable risk NE to SE. This is the sort of thing that it's easy to become complacent about as its a common feature of the Scottish winter. You might very obviously if you have any sense, stay well clear of the NE to SE aspects but wander into a high risk situation on descent on the N to S aspects.  The majority of avalanche incidents in Europe occur in these moderate to considerable forecast days as they occur most frequently in the season and folk become complacent (the familiarity heuristic) and that's why route choice approaching a climb and thinking about descent options prior to leaving and during a trip as wind and weather change should become part of your thinking.

Conditions have become dangerous, most often as a result of significant amounts of new snow, snowfall accompanied by wind or the snow pack becoming isothermal and threatening wet-snow avalanches. The snow pack is poorly bonded over large areas and human triggering is likely on steep slopes (steeper than 30°). Remote triggering is likely and large natural avalanches are to be expected.

Stay on slopes that are flatter than 30° for any part of the slope and be aware of the potential for avalanches from slopes above. If you do decide to walk ski or board on less steep slopes, be very aware of the surrounding terrain to avoid inadvertently crossing the bottom of steeper slopes or cutting down a steep convex rollover.

Usually this level of hazard is only present for a few days at a time. The smart back country traveller will stay in simple terrain until conditions improve. If you are caught out on a multi-day trip you may have to dig in and wait for travel conditions to improve and the avalanche danger to lessen.

These stripes in the avalanche forecast. My take is to think of them as landmine strips blown by the wind, lurking in eddies from cross loading when the wind blows across as well as down or over a slope, the colour of them is the sensitivity of the pressure plate to you the trigger. If there are enough of them the explosion will propagate setting of others, or if the surrounding slope is weak enough then it will slide with it. As you can see there are areas of High on slopes with a localised "considerable" and a"considerable" risk to the South.  A lethal combo of  narrow safe travel options making for events that will take lives if you don't tread warily and navigate with extreme care.

Extreme danger levels are rare in Scotland as usually this level is associated with buildings and roads or alpine villages under threat, and usually the result of unusually large amounts of new snow. The snow pack is weakly bonded and unstable. Numerous large avalanches are likely. The weight of the new snow can trigger avalanches on layers buried deep in the snow pack. Natural avalanches can release on slopes of less than 30° Back country touring is not recommended and often impossible. Avoid all avalanche terrain and keep well away from avalanche path run outs.

Avoid Groupthink
In psychology "Groupthink" or "Risky Shift" behaviour is well known in groups and most of us will be aware that we have given in to it or even encouraged it. I strongly believe that in avalanche incidents in Scotland this groupthink or risky shift has become the biggest education issue and maybe why we see large group incidents or group events as occurred in the Cairngorms when two separate groups were avalanched last winter. Much has been made of the quick response from folk training in the corrie who helped.  And good on them. What I am about to say is not a reflection on these helper folks choices, as I am sure they stayed in safe terrain.  The  "however" bit though is that just by being there and numbers increase with lots of MRT's training, and groups under instruction, then a larger "Groupthink" takes place. Groups less experienced or not under instruction maybe feel safe, what McCammon labels  as Social Facilitation.  I would call this a  "risky shift". It's often this way in the climbing and skiing honey pots such as the Northern Corries where folk gather. Aonach Mor or ScRL in Glencoe are other places. Even if the waggon wheel of death shows Red on these slope aspects, they are still the places to be seen by the instructor masses who are now at the height of their annual gatherings with paying students. These are the places instructors are familiar with, and therefore where less experienced folk feel safer with an apparent safety in numbers. They maybe went there when they were on a course. Group thinking on a large scale perhaps.

Better minds than mine have already written about risky shift and here's an excellent article on it The Risky Shift Phenomenon and Avalanches. This kind of stuff has been getting applied to avalanche instructor training for a while by AAA.  Do current winter mountain training schemes  include enough if anything on this sort of thing?  I put this as a question, as I am certainly not in a position to know, and maybe it is already covered. What I do know is that there is nothing that can change the pretty piss poor odds if buried and that pretty universally all of us involved in avalanche education are trying to jump forward and get to "no rescue".

No matter what we do, mountains and people are unpredictable. As a keen off the piste skier I have to accept that luck is also in there as well, as on good snow days I am first in the que and having gone through the forecasts, stability tests you are only left with how the snow feels under you ski's and gut instincts. Sometimes it's a very subtle thing where in the morning it feels wrong, and by afternoon the snow "feels" safe.  I don't know how the feck that would stand up in court! I also know its taken 40 years and I still can't always be sure it all won't go tits up one day. I also know that it pays to voice your opinion when in a group, and make your own choice, not getting swept along by the group and it's most vocal leader. Beware Risky Shift!

"Destiny is a good thing to accept when it's going your way. When it isn't, don't call it destiny; call it injustice, treachery, or simple bad luck"   Catch 22 by Joseph Heller

For backcountry travel, side stash/off piste, or indeed anything out of ski area and uncontrolled, always carry the three essentials of transceiver, shovel and probe and do a pre depart group beacon test and practise.

If you need an airbag you have fucked up but might survive. If you need your transceiver you have fucked up and probably won't!

2. Get a Beacon, Shovel and Probe. Some Transceiver Observations:

Some findings and observations from using these popular avalanche beacons on the last avalanche training courses in both shallow to very deep (3m+) burials. They are all adequate with the exception of the original tracker which although it might work is old. The newer version of the Tracker DTS/Tracker 1 is a bit better and still on sale. The T1 is a 2 antenna beacon and suffers from null points/signal spike unlike the excellent Tracker 2 (not being reviewed here) which is super fast. These 3 antenna beacons are all good purchases, but like all technology when used for scenarios that are not simple then their effectiveness is challenged and quirks come out. Only realistic practise with the beacon you own will make you the user aware of what these are, and work arounds.  What this means is practise and realistic scenarios to challenge you the searcher. That's what Beacon training parks are there to help you with. I have attempted to be non biased but declare a conflict of interest as I am an Ortovox retailer.

Auto revert or random transmit from rubber-neckers is the curse of the avalanche search. Be aware of it when on a long search, and be aware if its preset on or you have to activate it as part of the pre trip beacon check.

These beacons were used at the Glencoe BCA beacon training park and on scenarios created on ski 's and off piste in the ski area while searching for an analog Ortovox F1, analog SOSF1ND (re boxed F1), old Tracker 1's and 2's and a Tracker 3. All students were taught the primary basic search patterns of searching in series, in parallel, and micro grid, and only after lots of practise was marking used, and then only in the context of relying on a basic reliable search method should marking fail. All the three antenna beacons looked at here that show multiple burial icons did at varying times show multiple victims when only one was present and most often in deep burials. After group auto revert and radio/phone checks this still occurred when only one beacon was transmitting. This was from the very long pulse cycle of the old F1's getting the processor confused, but it also occurred in the deep burials with newer beacons and I wondered if each side of the deep beacon flux line was seen as a separate signal. Solving these issues is why we all need to practice.

I do a special offer of the pro level Ortovox S1+ to SMR and Ski Patrol. For professionals I recommend folk wanting an upgrade to consider this very advanced Beacon with its unique visual games type display. It takes you straight to the victim, has a very reliable "mark" feature and a host of other built in pro features such as actually displaying visually where each victim is with distance, a longer range (55m) than other digital beacons (most are 25m) and of course the smart antenna that gets you found faster. It has lots of programmable extras and via the menu in extremis the 3 mark feature can be overridden to 4+>. Also incorporated is a Recco reflector inside as back up and the smart antenna to get you found. In testing the unique "deep burial" mode solved the conundrum that less experienced users find in the Glencoe BCA park when some of the units are 1.5m+ buried. I have to teach the BCA "pinpoint in a line" and other advanced techniques to solve these usually, but the S1+ does them very well. If you are a pro or take groups this has other features that are useful, not least the partner check.
Ortovox 3+
I  sell a lot of these to ski patrollers and some MRT's (Killin MRT have 30). Very simple to use and reliable. The marking function on the 3+ is reliable but of course like all beacons marking gets problematic beyond marking 3 beacons.  The 3+ on deep burials suffered occasionally from null points and a signal was then re-acquired after switching back to transmit briefly, then back into search so easily solved. Students like its speed, simplicity and very clear display. Default auto revert is ON.  This would be my beacon of choice as value for money for most folk. It has the right balance of speed, ease of use and simple but reliable features including smart antenna orientation helping a victim be found more easily and a built in Recco strip so the victim is more searchable from a longer distance by the Recco system on organised rescue.  

BCA Tracker 3
The Tracker 3 is small, and can easily be carried in an inside pocket.  Its very fast processor is good, but the advertised range which is 40m is a little optimistic and I would say in most cases its only 30m necessitating a narrower search strip and a little more work from last seen point to signal pickup. The T2 is still faster IMHO and has a slightly longer range. The T3 doesn't mark a victim but will "suppress" one beacon in close proximity for 1 minute allowing the searcher to get away and lock onto another victim. I didn't always find this very reliable. However, it's "big picture" mode was useful in showing directions and distance to other beacons and did what it says, give a bigger picture but with the mark feature so much more reliable in newer beacons its just not as good as marking IMHO. Auto revert is default OFF.  Worth upgrading to Firmware 3.3 if you have one as it definitely improves the beacon. Its a great beacon for single searches or if you are better trained in avalanche searching. 
Mammut/Barryvox Element
The Element and its more expensive brother the Pulse are very popular beacons from Mammut with the internals from Barryvox a company with a long pedigree in avalanche beacons.  The one used had the latest software and had a very good range. The analog in the Pulse version is superb for an experienced searcher as the search distance increases to 60m (I got a signal at 67m on one). The Pulse in analog is also good acoustically as you can hear the pulse tones of different beacons.  The Element is purely digital and does not have the rescue send or unmark features of the Pulse. The Element like it's big brother suffered a lot from the "STOP" icon, requiring the user to stop and wait while the processor updated. On a couple of scenarios this got too long and only by switching from search back to transmit quickly and back to search was the signal eventually reacquired. Of the ones used here it seemed slower than previous models with the older software. Auto Revert Default ON
The original digital beacon, the Tracker DTS.  Plenty going 2nd hand as folk upgrade. These should be retired due to age IMHO. Save your dosh for a 3 antenna model. 
Tracker DTS 2nd edition. Also getting on a bit and only 2 antennas
The ubiquitous Tracker 1. Still on sale and probably the most common beacon carried for years.  It still works and is quite fast even if it only has two antenna's. I want to slag it off as we recommend that everyone these days has the more accurate 3 antenna beacons. However, the damn thing still works quite well. The additional training requirement of teaching how to overcome signal spikes is no big deal, most of the time. But, when it is it's time consuming. It is a lot less effective in deep burial scenarios and students must be taught to spiral probe, or probe in a grid to locate a deep victim, which takes a lot more time. Like its superior big brother the Tracker 2 the T1 has "SP" or spotlight mode which I have always liked as it narrows the search angle directionally and spotlights the next victim so you can then get away from the found victim, move to the next signal and allow it to lock onto it as it becomes the closest. Sometimes it's possible to jump from continuing with a micro grid search having used the SP mode and get a lock on the next victim. I tell my students get an upgrade to 3 antennas as its much better.  But, the T1 is still ok (only just - but consider an upgrade!) and it shows how far ahead of its time is was, but now there are better options IMHO. Auto revert default OFF
Tracker 2
Whats not to like. The Tracker 2 is a real workhorse. Reliable and easy to use. The first 3 antenna Beacon. If this had a "mark" feature it would be tremendous. Sadly it hasn't but, if you learn to search properly, along with using the SP mode you can be just as fast, therefore a slightly longer training requirement and its less out the box usable for multiple burial scenarios but is tremendous for a single victim search.

This new transceiver looks excellent and hopefully I will have one to review at some point. Coming from a company that has a good track record this should be an excellent beacon. I will write it up after a test

Your money would be well spent on any of the ones listed apart from an old version T1 or old out of warranty Tracker DTS. Even the 2nd edition ones are not worth your money, even though there are lots 2nd hand. Most often its from folk upgrading to a 3 antenna one so why be cheapskate and buy one off them. Get a 3 antenna one. These are just some thoughts from trying lots of beacons on the market and this is just one review. There are no bad ones and they all have quirks, so get out and practise as its really important you are slick as someone is depending on you.

Note. If you use old analog beacons to practise you may find the multiple victim icon coming on intermittently. These old beacons have much longer signal pulse and digital beacons sometimes interprets this as two signals.

4. Recco. Mountaineers are not Searchable - most of the time ...............

Don't get buried! But if you do you want to be searchable 
and found FAST!
Recco is another important part of the organised rescue strategy. Education and avalanche avoidance is primary, being found early by companions if it goes wrong is vital and prior practise makes this work. Organised rescue requires a triple response: Dogs, Recco and Probe Lines. Until now Scotland has only been able to apply two of the three unlike alpine rescue avalanche search where for years all three have been used. Survival is time critical. Much has been made of trauma being the main factor in poor survival in Scottish avalanches. Largely based on recent tragic avalanche incidents where trauma has clearly been the dominant factor.
These anecdotal observations and opinions make easy it to forget the victims where triple "H" syndrome has been the killer of which there have been many over the last decades. Anecdote though is not enough, and there is no recent data set from necropsy studies in Scotland, (if there is its not readily available). One thing is sure, being searchable and getting found quickly increases survival. Some Scottish MR teams already have Recco as part of their search strategy (Tayside, Glencoe, Cairngorm MRT's but not Lochaber) and Cairngorm, Glencoe and Nevis Range Ski Patrol. A good thing. I can imagine nothing worse than a victim recovery delayed because a search team did not have a detector and the victim is found to have either a Recco reflector or a harmonic on them. Recco is of course for "organised rescue". Everyone including Recco and the clothing manufacturers endorse the view that not getting avalanched through education and training is better than needing any search devices which may be too late. However, in the real world shit still happens and unless someone is "searchable" a rescuer cannot find them readily even if the poor victim has bottomed out of the survival curve. We should not forget Robert Burnett's remarkable 22 hour survival in the Southern Cairngorms. All victims surely deserve the benefit of the doubt and rescuers throwing all resources at an attempt for a live recovery.
Small sticky reflectors that can be attached to boots or helmets
As "off piste" and "Backcountry" skiing grows in popularity there is every reason to imagine that being more searchable can save lives.  Nothing can replace education and prevention, or fast effective companion rescue with beacon, shovel and probe, but as ski patrols and MR teams take up Recco and the reflectors can be bought and carried then the chance of getting found alive by organised rescue if on scene quickly increases. I would recommend two reflectors to mountaineers, One front top and one back bottom.
Sewn in reflector

So Recco is here in Scotland and its great to see the take up by enlightened Scottish rescuers adopting alpine best practise. Who knows when Recco will save a life, but if it does it's job then its been donation money well spent.

Glencoe Mountain Transceiver Training Park Success

Avalanche Avoidance and Companion Rescue
The most up to date training system in use at Glencoe Scotland

Eight independent beacons that transmit a signal at the international standard for avalanche transceivers of 457kHz are permanently buried in up to 4m of snow at Glencoe Mountain ski resort. They are looked after by Glencoe Mountain staff, Ski Patrol and Davy Gunn who runs avalanche education training on Glencoe Mountain

Hamish at the 2011 opening
In collaboration with Anatom who supplied a wired starter training system to get things going in 2011. Glencoe Mountain Resort provided a piece of snow sure land, help from the staff and some financial help to start the training park 4 years ago.  The original park was opened by Hamish MacInnes the famous mountaineer and rescuer. Winter 2015 money raised by Clachaig Inn at their annual winter series of mountain safety lectures at the hotel provided funding for the new wireless avalanche search training system in place this winter. The hotels owner is a member of Glencoe Mountain Rescue and a friend of both his and Davy Gunn’s (Chris Bell) was lost in an avalanche in Glencoe in 2013 where 4 people lost their lives in one avalanche. The original wired system is now in use at a training park at Glenshee ski centre and it’s hoped to raise funds to get a similar and more effective wireless system in place there. As at Glencoe, the one at Glenshee provides an accessible training venue for local mountain rescue teams, mountaineering groups and off piste and touring skiers.

Practising digging effectively, a crucial
and often overlooked part of avalanche rescue
The general public has free access to use the training systems which stays out all winter. All they have to do is check in with the Glencoe Mountain staff or  ski patrol to see if it’s already in use that day. Each of the eight buried beacons also has a RECCO reflector inside so that mountain rescue and ski patrol can practise using this alternative search system as well as transceivers. 

Organised rescue teams use RECCO which is harmonic radar that can also be used from a helicopter. RECCO is a standard search tool by mountain rescue in Europe. Three Scottish mountain rescue teams, and threes ski patrol's use it. No search and rescue helicopters have adopted it in the UK for avalanche rescue to date but the hand held can be used from a helicopter with an adaptor system from a 3rd party manufacturer. I have one here in Glencoe as I am also the UK trainer for Recco.

The training park beacons are buried deeply in the snow so that searching for them proves difficult, simulating searching a real avalanche for a victim.  As it’s wireless there are no wires to degrade or get cut by shovels as folk dig, and different avalanche burial scenarios can be created from single to multiple victim burials by alternating which buried beacons are transmitting from a control box. When a victim/beacon is found by a searcher, contact with the buried beacon by a snow probe sends a signal back to the control box confirming a success.
Ortovox 3+ a modern fast avalanche transceiver
Training is available from me in  avalanche awareness and transceiver searching

Every skier going off piste or touring in the mountains should carry three essential items. A transceiver to be located or locate a buried companion, a collapsible snow probe to confirm the victim’s location and a strong aluminium shovel to dig them out quickly.

Glencoe ski patrol practising in the park
Recovery of buried companions in an avalanche is time critical with a 90% survival if victims are located and dug out within less than 15 minutes. After this time survival is very poor, therefore practise in locating and digging is critical. One of the training beacons is inside a resuscitation mannequin so that digging it out is like excavating a real victim and some care is required. The park importantly provides an opportunity for ski patrol to talk to those practising and emphasise the importance of avoiding avalanche terrain by interpreting the area avalanche forecast and local weather effects and therefore make wise and safe choices avoiding avalanche terrain for the day.

The enthusiasm and support by Glencoe Mountain owner Andy Meldrum and his staff by providing snow sure land, tending to the park and investing in its upkeep is tremendous. A particular mention of thanks to Glencoe Ski Patroller Keith Hill who is always on hand to give sound advice to skiers and boarders and who maintains the park.
