Sixteen IMSARU members and a guest from the Idaho Division of Aeronautics spent the weekend training in the snow near Mores Creek Summit. The trip began with sunny skies and warm temps, but overnight the weather stepped up the challenge a bit by adding 5″ of new snow. Members used a full array of structures including trenches (with snow or tarp roof), snow caves, tents, and tree wells. This is an annual training event for IMSARU, giving members a chance to hone their preparation, gear, and tactics for use in a cold and possibly wet environment. The goal is to expose members to conditions seen during a winter search, and prepare them for the possibility of spending a winter night out with a stranded subject, when night-time extraction is not available.
