What to do if You Get Lost

Imagine... it's a beautiful day. You've taken your camera and headed out for a short hike away from your campsite. The wild flowers are compelling and you wander about aimlessly for a few hours. Two rolls of film later, you begin to head back for camp. Suddenly, nothing looks familiar. You look around for a while, trying to find something, anything, that looks familiar. As dusk approaches, your heart beats faster and you become very anxious. You have nothing but your camera and two spent rolls of film and without a flashlight, it will be impossible to find your way back. Your head sweats and your heart pounds feverishly as you begin to feel the panic associated with being lost


Discovering you are lost in the backcountry can be a frightening experience. This feeling can be compounded by the five basic fears: that of being alone, darkness, animals, suffering and of course death.

STOP!
At the moment you realize you are lost, the most important thing you can do is S.T.O.P. (Sit, Think, Observe and Plan). Do not run off frantically looking for a way out. Rather, stop and assess your situation! Use your head, not your feet. At this point your brain is your most important piece of survival gear. The first ten minutes of being lost are when most search fatalities make their deadly mistake.

Whatever you do, don't panic. In most situations you can survive 3 days without water and 3 weeks without food. Force yourself to breathe deeply and slowly. Rest assured that by  remaining calm and relaxed, your chances of survival, which are quite good already, have increased by 50 percent. Your primary goal now should be to stay alive, not to find your way out. Help will be on the way soon after you are reported missing. Sheltering the body and
conserving energy is your greatest concern right now.

Once you determine you are lost, your actions during the first few minutes could play a significant role in your survival. 

Get Loud!!!
When you first discover that you are lost, stay where you are. Yell or blow a whistle 3 times to signal your party or any others within earshot (a whistle will carry farther than your voice and requires less energy). Wait several seconds, then turn 90 degrees and try again. Do so several times in every direction. If you have no whistle, yell "HELP" rather than a friend's name. Doing so will help assure that your distress call is not ignored.

If someone yells back, let him or her come to you. Rock walls and valleys play strange tricks with echoes and you may lose your potential rescuers by attempting to locate them. In addition, your rescuers are most likely a group of people, so they will have a better chance of finding you than vice-versa.


If you do hear someone yell back. No matter how faint his or her yell may be, stay put and keep yelling. They may sound far away only because they are facing away from you and have not yet ascertained from where you are yelling. If you are near a loud stream, move away before yelling or whistling for help. Be certain to mark your way back to the stream, however, as you may want to follow that stream later if your calls go unanswered. The same is true for windy areas where a howling gust can be quite loud. Remember, someone may hear your call at times when you cannot hear his or her reply, especially in windy areas. Do not give up yelling or whistling simply because a reply is not heard.


Stay Put
When setting up a search, mountain rescue teams follow certain priorities and make certain assumptions about their subjects. These assumptions are based on behavior patterns of lost subjects. An understanding of these assumptions may help guide you to a place that is searched early. The first members of a search party are quickly dispatched to the point at which the subject was last seen (strangely enough, referred to as the "point last seen "). They follow trails and streams near this last seen point, yelling the subject's name and blowing whistles. This simple fact is reason enough to just sit still and wait for rescuers to find you. Unfortunately, nobody does. Less than 30% of lost persons are found within one mile of the last seen point. Additional rescuers search areas of high probability near the last seen point. Statistics on behavioral patterns of lost hikers have shown that 88% walk downhill when lost, 73% find and follow a trail or path and 82% are found in open areas.
Based on these facts, field teams often search downhill from the last seen point before spreading the search out in other directions.

Air searchers are generally used soon after you are reported missing and weather permits flying. Plan to stay near open areas and be ready with signals.

Remember, your brain is your most important piece of survival gear. Keeping your cool and doing the right things in the first ten minutes will greatly increase your chances of a quick and uneventful rescue!

Avalanche!!!! The Snowpack Variable 


Snowpack is the last variable that we will use for clues.  By combining the clues you observe, identify and feel from the snowpack, a decision should easily be made whether or not the snow is unstable and has potential to slide. Some of the signs of avalanche are obvious.  The following clues are direct indications of instability in the snowpack: 


Recent Avalanche Activity 
Again, recent avalanche activity is the best indicator of dangerous slopes, especially when it is on slopes of similar aspect and steepness.  In other words, if you see the debris from a recent avalanche, know that there is danger of additional avalanches on similar slopes. 


                                              A bad day on the snow 

Recent Wind-Loading  
Recent wind-loading is another indicator of avalanche danger.  Smooth "pillows" and cornices as well as snow plumes of the ridge tops are indicators of wind-transported snow.  This means increased stress is being exerted on the snowpack due to the addition of the wind deposited snow.  Furthermore, wind deposited crystals develop dangerous "wind slabs," since this type of crystal is subject to numerous collisions while the snow is wind-blown. 


Hollow Sounds 
You must use your ears as you evaluate avalanche hazard.  "Drum-like" or "whumpf" sounds that occur under your feet indicate unstable slab conditions.  Also, pay attention to distinctive settling sounds; feeling the snow settle or drop are clues of an unstable layer of snow...indicating a dangerous avalanche condition. 


Shooting Cracks 
Look closely at the terrain you wish to cross.  Cracks in the snow around you are an excellent indicator of avalanche danger, especially if they are occurring around you as you move across the snowpack. You should not only avoid the slope where you see or produce cracks, but also any slopes with similar profile and/or orientation. 


Snow Stability Tests 
Through additional training, you can learn to recognize the weaknesses in the snowpack by evaluating a cut-away of the snow layers.  For now, just remember that avalanches occur when a weak layer in the snowpack fails.  Your ability to recognize these weaknesses will help you make an educated decision regarding safe backcountry travel. 


Conclusion 
In summary, by looking, listening and feeling you should be able to recognize, evaluate and avoid avalanche hazards that you may encounter on your next backcountry trip.  You must be thinking avalanche whenever you are on or near slopes, regardless of the slope size and time of year.  By always thinking avalanche you will be much more observant, you will gather more information from clues, and you will become a better decision-maker

Situational Awareness in Mountain Rescue Operations Stage 1 - Perception of the Relevant Information




Yogi Berra once said, “You can observe a lot by just watching.”  Observation is the key to perception.  


In this first step of situational awareness, we are looking for clues.  These clues can come in many forms, including: 
• Sensory clues - something you see, hear, smell, touch; 
• Anticipated clues - something that comes from prior experience; and 
• Innate clues – something you just “feel in your gut.” 


In conventional search missions, for example, rescuers are looking for CLUES more than they are looking for the missing subject.  Why?  Simply because there are far more clues than there are missing subjects, and by finding and following clues, one can find the missing subject much more quickly. 


The first stage of situational awareness – perception – is arguably the most important stage.  After all, without perception of information, one cannot really comprehend, interpret and draw conclusions. Many accidents in search and rescue operations result from a series of different things happening.  There are often a number of contributing factors that, if occurring individually, might not have resulted in an accident.  Break any rescue accident down, and you will often find that there were a number of elements that came together to make that accident possible. 


In this important perception stage of Situational Awareness, rescuers need to be very attentive – not only to the occurrence of situations that are beyond their expectations, but to the frequency and number of those situations. This perception stage requires that you OBSERVE!  In order to be an effective observer, one must remain attentive.  This can be one of the greatest challenges to a search and rescue professional, as periods of  inactivity and boredom can hamper one’s ability to be an effective observer. Similarly, searchers and/or rescuers who are overworked might not be able to observe the environment around them.  This too can be a serious detriment to one’s ability to be an effective observer. 


Stay tuned to our blog for the continuation of our discussion on Situational Awareness with Stage 2 Comprehension and Interpretation of the Relevant Information.
