"Let's Face The Music And Dance" ..............

Better to avoid having to get the search tools out in anger!
A lucky escape in a slide yesterday and from a localised hot spot as well forecasted on NE aspects by the local SAIS observer. The snow pit profile shows faceting under the icy crust. Things are setting up for longer lasting instability both from deep faceting under the crust and also the continuing snowfalls driven by strong winds on top of crust. While yesterdays slide had no consequences as it was a clean run out and the victim stayed on the surface, the victim was on their own. At the time of the slide he triggered there was poor flat light. When it cleared it was easy to see the pillows of localised danger as the snow was denser and reflected light less. Further around the mountain at a mid point on the NE facing piste overlooking Creis there was a West facing pillow of excellent snow running from the piste slightly due west overlooking the Cam Glen. Folk were nibbling at the edges getting half a dozen turns in each cut moving further down and round West not realising that the aspect had changed and the angle crept up. Very risky behaviour as its loaded and tips in at 32 deg and has a fucking great hole at the bottom if it unzips. The obvious risk was where the avalanche occurred and although it could have been worse was at least a clean line.There is nothing clean about the Cam Glen gulch. It's a high consequence line even in a small slide. Remember my post from a while back on 4 "A"'s and 3 "C"'s   >>>> CONSEQUENCES!

There may be trouble ahead 
But while there's music and moonlight and love and romance 
Before the fiddlers have fled 
Before they ask us to pay the bill and while we still have the chance 
Soon we'll be without the moon, humming a different tune and then 
There may be teardrops to shed 
Make sure there are no teardrops by reading the SAIS forecast and thinking about what's going on.

Avalanches, Education and a Good Month

January has sure "come in like a Lamb - gone out like a Lion" as the old saying goes. Currently the mountains above 600m are loaded with snow. The rapid rise and falls in temperature above the summits has at times stablised the snow pack with water penetration, but like to today its often followed by hail/graupel and then drops in temperature. Snow being cold water, is dense and sticky when wet, dry and fluffy (powder) when dry. Wet on top of dry, thing's can go awry - dry on top of wet the ski's are a good bet. Wind, wetness and the wet grain size in a rounding phase can be just as dangerous as the faceting in a growth phase. It's all part of the Jenga of a snow pit with layers of different density and weight and why we are in a high risk phase and need to take care.I am not a snow scientist but we are very lucky in Scotland that we have the SAIS to give us area forecasts with a really good narrative which folk often fail to read. Read the forecast and think about what its telling you and have a plan A and B. 
Getting stuck in with the shovel at Glencoe Mountain
January has been a good month on the avalanche education front.  Glencoe Mountain owner Andy Meldrum and the staff on the hill at Glencoe have been tremendously supportive. I have run five courses so far for Freeskiers, Ski Tourers, Split boarders/boarders and some mountaineers. Last course is 31st Jan but more will follow if there is demand. These courses have been supported by Anatom who import BCA and follows the BCA 101 teaching format. Each student from now on will get a copy of the BCA DVD "Take Charge - Leading a Companion Rescue. I have also had help from Ortovox with safety academy booklets for students providing an easy reference text for folk to take away. The beacon park at Glencoe is a great training aid and the protable Ortovox STS training system I have gives flexibilty with an 8 transmitter portable wireless system. The course is very much about planning and avoiding trouble using four A's & 3C's as a thinking tool. Good habits, group psychology and thinking yourself out of trouble not into it are the basic concept. The fundamental principle is that we should all carry a beacon, shovel and probe (and maybe if you have the money an airbag) but your decisions should not be influenced by them, as if you need them your have made a bad decission somewhere. Being human shit happens. Students on the course have had a variety of beacons and its always interesting to compare performances. All the digital beacons are good and effective and the best one is the one you know and practice with. One of the things that hits home the hardest on the rescue side of the course is how hard the digging is and how much time it takes. Survival of your friends comes down to how organised and practiced you are at digging, and the quality of shovel you have. So far we have produced some excellent diggers on our courses!

Go Pro - Tracker Beacons & SP Mode

I posted this link of Go Pro footage of a slide on Crystal Mountain on my business Facebook page CrankitupGear Glencoe. It appears a shambles and it's very easy to criticise what went on, but if you have ever been in this situation, especially with skiers, when very quickly a large group can back up and either help or just be on scene rubber necking, you will know it's not an easy thing to manage a search, and neither is it easy doing a signal/coarse/fine search in deep powder.  I once found a victim well below the end of the tip of the slide they had been taken on having stayed on the surface but who had then submarined off the end under the deep powder for several metres. It's not easy searching in deep soft snow. However, there are a few points that I guess are worth going over, none of which are criticisms just observations and a look at the merits and uses of  Tracker beacons. 
T1 was the first digital beacon and is still very fast and easy to use but requires knowledge of signal spike at close proximity and how to get through it which is actually very simple and does not detract from performance when users have practised.
The guy with the Tracker 1 was filming with what was apparently a Go Pro camera. Without that we wouldn't even be dissecting the event. Cameras affect a beacon signal, especially chest mounted Go Pro's, so GO PRO when on beacon receive mode is a NO GO.  He had a "last seen point" and went for it with his T1 beacon. T1 is an older two antenna beacon but despite this it still beats the pants of many new three antenna beacons for speed.  You just have to be aware of the signal spike in the fine search phase and when you know what it (signal spike) looks like its an easy thing to work through and won't slow you down.  In the video there were a lot of folk perhaps still on "send" but the guy was getting a signal and was nearly on the money. The thing with a beacon like this is that it's easy to be going 180 deg in the wrong direction, so if the distance reading goes up but the direction is locked in, then you're walking away from the victim. Hard to walk away in chest deep powder in tree's! That's why a good coarse search, not too fast, will stop you over running the airfield before you land the plane and get onto the runway on the surface for the pinpoint search and probe hit. Trackers 1 and 2 have "SP" mode which might have been useful to narrow the search direction down as if it was multi victim burial (which it nearly was). Most folk I come across do not know how to use SP mode effectively.  

SP mode is a very handy feature. Many beacons "auto revert to send" as a default setting after four minutes of standing still, which is a useful safety feature but causes mayhem in a real search and why those not searching should be in an area off site and safety and either have beacons off, or all on receive. Trackers are auto revert default set as OFF unless the user switches it on by turning on the beacon with SP/Options pressed until AR appears on screen at start up. 

When searching for multiple victims the SP button will narrow the search strip from the 5 LED display at a roughly 180 deg arc to the middle 3 LED's and roughly 75 deg and it will show all signals in that narrow arc. This makes it more directional although your still on a flux line not a straight line. The beacon not the searcher is rotated until a signal is picked up and only then does the searcher turn in that direction then immediately  walks in the direction of the signal locking the beacon onto it then press SP  returning the beacon to it's normal search mode. Remember that this arc is also 75 deg behind you and its not until you get a decreasing distance reading that you know you are locked in and going the right way. Combined with the DAV "3 Circle Search" method, this is a powerful tool in multiple burials negating the need for a "mark" feature. I would recommend that even those with beacons that have a "mark/flag" feature also learn this search method as a fall back as marking in close proximity multiple burials can be problematic.
3 Circle Method
In mixed groups I find all makes of beacon carried and its pot luck that the guy with the "Pulse" beacon  is the one left on the surface able to run around marking. In training I cover all the search options from grid to 3 circle and the hazards in close proximity burials of signal overlap and marking. It's always worth reiterating fundamental questions such as how many in a group and how many on the surface so its just basic maths to know how many your looking for and how many signals to find.
Three antenna T2 is super fast, no signal spike and has a multi victim indicator.  The fastest beacon in all tests and super directional.  Advanced  or professional users must practise using the SP mode and be familiar with the DAV 3 circle search method.  Basic users get digging and switch the first found victims beacon off and then go to the next one unless you have lots of helpers and can continue searching for other victims.
In fact a multiple burial is only lots of single burials and if the shit hits the fan in a small group then its shovelling that's crucial and I would advocate digging out the first person located asap and switching off their beacon then starting another search. If you have lots of manpower then fair enough get through the debris and locate the other victims. As you will see in the video probing is really important to locate a victim and if there are lots of folk with probes doing nothing then get them poking around. Although the ski patroller in this clip wanted the site cleared as he wanted a dog in, then paradoxically the dog sometimes works better at a probed site as scent is released. The downside is that the victims air pocket had been trampled over. A bit of a no win situation.

Breaking Bad - Controversial Opinions!

Avoidable or bad luck? BBC tonight "One Wild Winter in the Scottish Mountains" claims experts know why. "The avalanche does not know that you are an expert" wrote Andre Roch. Scotland has always lurched between a martime snowpack where instablities are short lived, and a continental snowpack where stabilities or instabilities are longer lived.  It's not new, or a revelation! I thought I would post the article below as it provides another side of the debate where some folks voice the opinion that there is no bad luck - you make your own choices therefore avalanches are avoidable.  True perhaps - but its never that simple and to err is human ........................

Mistakes in Avalanche Rescues

Worth sharing this old extract from the Avalanche Review
The Avalanche Review, Vol. 9, No.6, April 1991Copyright © All Rights Reserved; AAAP

Don't Create a Bigger Accident than Already Exists: 
Mistakes in Avalanche Rescues 

On June 14, 1987, a sheriff's rescue group responded to the call of a mountain climber buried by an avalanche on the slopes of Mount Borah. Even though trained personnel from Idaho Mountain Rescue were on hand at the staging area, the sheriff kept them from entering the field. He indicated that his personnel would go the site first and assess the situation to see what resources were needed.

According to the American Alpine Club's Accidents in North American Mountaineering, the sheriff's team of four, wearing blue jeans and sneakers and carrying one rope and a carton of soft drinks, could not reach the accident site, as the group lacked experience and the necessary equipment. 
With darkness approaching, the sheriff, concerned for his personnel, secured a helicopter to drop sleeping bags and food for his team. On a fly over at 4700 meters, the helicopter crew dropped the supplies. The rescuers at 3450 meters dove for cover. Needless to say, the supplies were well scattered during the 1250-meter fall.

The rescuers survived the bombardment of supplies and survived the night, only to be chased away the next day by an electric storm. At that point, on June 15, the sheriff suspended the search. On June 19, the sheriff's small team returned, but this time with members of Idaho Mountain Rescue. Finally, after probing, they recovered the body the next day.

Mistakes, Errors, Slipups, Blunders
The first rule of any search-and-rescue operation is "don't create a bigger accident than what already exists." Though few avalanche rescue operations are conducted without any problems, trained and experienced rescuers practicing good decision-making, with a dose of flexibility, keep most rescues on track.

After reviewing the three volumes of The Snowy Torrents, reflecting on my own experiences on over 20 avalanche search-and-rescue operations, and speaking with other rescue types, I have put together a list of repeated mistakes made during avalanche rescues and I offer some solutions to avoid these errors. "Repeated mistakes" is the important term; all the mistakes identified have been repeated by others at different times and in different places. I follow a theme started by Dale Gallagher in the first volume of The Snowy Torrents to "point out the mistakes as lessons for us all, not as a criticism of the individuals involved."
Mistakes made by rescuers can be grouped into four categories: (1) poor organization, (2) mishandling the witness, (3) inadequate hasty search, and (4) mismanaged search. Most of the cases involve organized rescue efforts; I also looked at small group rescues where members of the party involved in the accident made obvious mistakes, usually at the hasty search stage.

Poor Organization
The four points listed below arise from a lack of organization and virtually guarantee chaos to some extent during the rescue:

  • no plan
  • divided or uncertain leadership
  • lack of proper equipment
  • failure to request available rescuers
Organizational problems generally arise from two sources: no plan or an unpracticed plan. Even volunteer search-and-rescue groups and ski patrols must have a written plan, so that all members understand their potential role in any avalanche rescue. Besides spelling out the personnel responsibilities, the rescue plan should cover equipment management and identify additional resources such as other rescue groups, helicopters, lighting systems, food, etc. Controlling the chaos arising from rescues is one of the duties of the rescue leader.

The lack of proper equipment, both rescue and personal, has slowed down many a rescue. A rescue plan will aid in having the rescue equipment where it's needed and when it's needed, but there is no substitute for an experienced watchful eye for making sure that individuals are properly equipped. For rescues in and near developed areas, being well equipped is not nearly as critical as it is for rescuers going into the backcountry. Be alert: trained rescuers are just as apt to forget a piece of equipment or clothing, or to not have the right gear, as volunteers. For example, soft-soled boots, like packs and snowmobile boots, are perfect for probing, but can be dangerous if one must climb a steep icy bed surface.

Once again a rescue plan will help in securing additional rescuers. The plan should list other available rescue groups and at least two contact names and telephone numbers. Don't let pride stand in the way of performing the mission, as the sheriff in Idaho did. Ski patrols and rescue teams have suffered from this same affliction at one time or another. Not long ago in Colorado, during one backcountry avalanche search, one ski patrol would not call in a second one, even though the first had only four members available, and the second had 28 members waiting less than 20 minutes away. Call in all available rescuers. Rescuers would much rather be requested and then turned back while en route than not be called at all.


It is not known if an avalanche victim has died on account of a poorly organized rescue operation. But in one case, in 1958, in Utah, a rescuer was buried and killed in a second avalanche after the rescue command fell apart, lost control of the operation, and allowed column teams to scatter on their way to the accident site.

Mishandling the Witness

It is within this category that the greatest number of mistakes have been made. Blame cannot be a fixed to a witness, but rather to the rescuers for how they handle, interact, interview, and interpret the words of the eyewitness. In one extreme case a zealous sheriff, shortly after a large accident, told the press that the two eyewitnesses, who also triggered the slide that buried and killed four skiers, would be arrested and charged. Rumors hinted at felony manslaughter. Fearing the law, the two quickly went into hiding; it took the better part of a day to get the witnesses to come forward to assist in the rescue. No charges were ever filed.

Common mistakes regarding witnesses are the following:

Inaccurate information regarding the:
  • last seen area
  • number of victims
  • location of the accident site failure to return to the same vantage point
  • failure to hold and question witness emotionally unstable witness
  • failure to keep track of the witness at the accident site

Though a witness would never purposely give bad information, experience and the record show that inaccurate information is not uncommon. Poor interviewing skills on the part of the rescuer is a problem, as well as the uncertain witness who did not carefully watch the accident happen.

Because of inaccurate information we no longer use the phrase "last seen point," but now use "last seen area." Buried avalanche victims have been found above or well to the side of the last seen point, out of the anticipated flow line. Several times I have found that witnesses identify the place where they last saw their buddy somewhere between the actual last seen point and the point to which the person was headed.

For example, in 1987 two snowmobilers were headed towards a stand of trees when they triggered the slide. They marked the last seen point immediately next to the trees. In reality the two snowmobilers were caught several hundred feet away from the trees.

One of the first questions asked by a rescuer is "How many people are buried?" What seems like a simple question, requiring one simple answer, is not always so simple. Witnesses have given inaccurate information on the number of buried victims. Inaccurate counts seem to arise when a witness, typically caught in the same slide, thought that other people were close by but did not know the others. The point is that when the witness knows the people nearby, he or she pays closer attention to who they are and where everybody is on the slope. Rescues have ended prematurely, only to have the rescuers called back hours later to search for and then find someone who was reported missing later in the day. If there is any question as to the number of victims, search the entire debris area.

Though rare, in two cases the witness was too emotionally unstable to give information to the rescuers. Usually witnesses are very willing to assist, and often, if rested, make good searchers. In 17 years of mountain rescue work, I have not encountered this discomfiture, but a situation I have experienced is the grieving loved one who arrives at the command base. Both situations-the grieving person and the emotionally unstable witness-require giving comfort and support. If faced with either situation, arrange for a clergy member to come to the command base and meet with the person. Having a man or woman of the cloth present seems to offer greater emotional support than a caring rescuer, sheriff's deputy, or social worker.

The failure to hold and question witnesses has caused grief for several rescue leaders. Though it is sometimes easier said than done, be certain that you hold the witness and make sure to get names, addresses, and telephone numbers of all witnesses. Assign someone to keep track of them, since, with no record, once a witness leaves, so do the answers to your questions. Only a few weeks ago, in Colorado, a slide buried a portion of US 40 on Berthoud Pass. It was suspected that two out-of-bounds lift skiers might have been trapped in the debris. Three separate groups of skiers reported the slide, and all were allowed to slip away with not even one name or phone number recorded. If that happens and you think someone might be buried, search the avalanche first and ask questions later. Do not waste time trying to track down unavailable witnesses.

Getting the witness back to the same vantage point is critical for getting accurate information. A witness trying to identify tracks or place the last seen point from somewhere other than the spot from which he or she saw the accident will make mistakes. It will require extra effort but get the witness back to the original vantage point as soon as possible.

Once you have contacted the witness, keeping track of him or her is very important. During a search next to a ski area a number of years ago, a witness, who was riding a lift, slipped away for more skiing. In this case the missing witness caused only a minor inconvenience to the search operation because the search area was very small. However, during a rescue in 1967, an eyewitness wandered away from the accident site. Hours later the witness, a boy, was found dead from hypothermia less than a mile away.


Inadequate Hasty Search

A hasty search performed by survivors or witnesses of an avalanche is being done while the clock is ticking on buried victims.

Therefore mistakes made may truly have deadly consequences. Four types of mistakes made during the hasty search phase are:

  • not doing one
  • not searching the entire area
  • missing visual clues
  • not being proficient with avalanche rescue beacons not finding the accident site
The first two points are related. In some accidents, members of the party left the site without doing a thorough hasty search and missed visual clues that might have saved a life. In December of 1984, two backcountry skiers were caught in a slide near Aspen, Colorado. The survivor dug herself out, made a fast check of the debris and left the site to notify rescuers. Hours later, a hasty search by the rescue team revealed a ski tip sticking from the snow. The victim, shallowly buried, had died.

Organized rescue teams have also done incomplete hasty searches, or not hasty searched the entire area, before starting the probe lines. Only later as the probe lines marched up the debris did rescuers spot an obvious ski or pole sticking out of the snow.

The initial hasty search of the avalanche just a few weeks ago on Berthoud Pass (mentioned earlier) consisted of a beacon search. Probelines were begun immediately on the roadway so that the road could be opened as quickly as possible. Only later were the likely burial areas, about two dozen different trees, searched. Fortunately no one was found in the slide.

The best documented case of probing too soon happened in Washington in late 1962. Shortly after probe lines were initiated, a ski pole was found in the snow. still attached to the skier. The skier, unconscious when dug out, quickly regained consciousness and made a complete recovery.

Avalanche rescue beacons are lifesavers but require practice, practice, and practice. Chaos struck a group of experienced and well-equipped backcountry skiers in Utah, in 1979, when one member of the group did not switch his beacon back to receive after two other skiers in the group were buried. Confusion of the three signals caused a delay of several minutes. One skier survived, but the other did not. The time lost because of the beacon confusion cannot be directly linked to the skier's death, but it is certain that a less experienced group would have been hopelessly confused and two fatalities would have resulted.

Lady Luck was with a group of four backcountry skiers in Colorado in 1988, when three of the skiers were completely buried in a small slide they triggered. The group was well equipped, and all had beacons and shovels, but only one of the members was trained and practiced in the use of an avalanche rescue beacon. Two others in the group had very limited training, while the fourth had no training whatsoever. It was this fourth member who was not caught in the slide. Relying on instincts, rather than a beacon he did not know how to use, he quickly spotted a hand protruding from the snow and dug out the most experienced member who in turn used his beacon to find the other two buried skiers. They survived, and today all are very proficient with avalanche rescue beacons.

Remember to listen as you search the debris, as dozens of shallowly buried avalanche victims have been recovered alive when rescuers heard yells coming from under the snow. In one case a tired shoveler moved away from the search area to rest. As he sat down on the snow, the still conscious buried victim heard him and yelled. The startled rescuer quickly alerted the others and soon the man was free after a four-hour burial.

If the hasty search fails to turn up clues or enough clues to establish the likely burial areas, go back and redo the hasty search. The more clues, the smaller the search area. Once probe lines begin, the speed of any rescue falls dramatically.

Even with a coherent witness, locating an accident site in stormy weather can be difficult, and nightfall might make it impossible. It was mentioned above in the section on handling witnesses, and it deserves additional comment here: incomplete questioning has misled a number of rescue leaders in determining the exact location of an accident. Some hasty teams have wasted time in trying to get to an accident because of vague or poor directions. More careful questioning might reveal the easiest and safest access for the hasty team.

Mismanaged Search
Typically, once the probe lines begin, few serious mistakes occur while searching the debris. Minor setbacks do arise, such as rescuers dropping personal clothing on the debris and someone else believing the piece to be a clue. But four serious mistakes have arisen from time to time:
  • not probing the entire debris
  • not starting at the toe
  • not digging where dogs alert
  • contaminating the debris for search dogs
The first is not probing the entire debris. Imagine the surprise of one highway department heavy equipment operator clearing a road when he unexpectedly found a buried station wagon. The driver of the buried car had been buried eight hours, and now was saved more by providence than by plan. Rescuers, hours earlier, had probed part of the debris and stopped after deciding no other vehicles were buried.

In several rescues probe lines were not started at the toe of the debris. Perhaps there was some clue that warranted searching higher up, but in several cases the victims were found later, in the toe of the debris.

The nose of a trained avalanche dog is perhaps the most efficient search tool a rescuer has. On several occasions dogs alerted only to be pulled away because the spot was not where the human rescuers expected to find a buried victim. Trust the dog.

The contamination problem arises from sloppy rescuers. Not always is it possible to get a rescue dog to the accident site with the first wave of rescuers, so it is important to keep the debris clean. Sure, a trail of tobacco juice marks where the probe line searched, but the extra scent makes the dog's job even more difficult. Do not allow rescuers to throw food scraps, spit tobacco, or relieve themselves on the debris.

Some Final Thoughts
Many more lives will be saved by education, avalanche control work, and precautionary measures than will be saved by rescuers. Most buried victims will not survive long enough, no matter how well organized, prepared, and equipped the rescuers are. But some buried victims do survive, and all victims should be given the benefit of the doubt that they might be found alive.

Mistakes and problems do arise in avalanche rescues, but we can learn from the misfortunes of past rescues to prevent future mistakes. Organized rescue groups must have a written rescue plan and have the correct equipment already located in strategic locations. Persons who may assume leadership roles must know the plan. Every season the plan must be practiced and updated. Conduct simulated rescues and practice sessions periodically to keep rescuers sharp. An organized, prepared, and well equipped rescue team may make a difference and can save someone's life-maybe your own!
