In Suspect Terrain: • Take the time you need to: • Make a plan- scout from several spots • Post a spotter or 2 • Find real safe zones to aim for that have good visibility
In Suspect Terrain: • Ski one at a time • Have pre-set clear signals, try a talkabout radio for help with the line • Don’t ski above your partners • Pole straps and ski leashes off • Ski carefully and lightly
SELF RESCUE Yell while you attempt to ski out of the moving snow Get rid of skis and poles, or snowboard Fight hard! (swimming motion) Keep day pack/ditch expedition pack Create air space, hand to surface Stay calm, breathe slowly, dig to surface if you can

Companion/beacon rescue …but if you get to them fast enough, you can save them If recovered within 15 minutes, chances of survival are almost 92% At 35 minutes, survival rate drops to 37% % Recovered Alive After that, the success rate is extremely low.

COMPANION RESCUE • Two priorities: Safety of Rescuers and SPEED • Ask the 5 questions (see next slide) • Appoint a leaderwho will: - interview observers - information point person - big picture person - prepare for rescuing a cold/c-spine injured person • Quick search is the most important first step - likely burial spots - surface clues (do not move them, but check beneath)
5 Questions: • Is the scene safe? • How many victims? Wearing transceivers? • Last seen point? • Transceivers to receive or OFF? • Cell phones off?
Multi Person Group Appoint a leader 5 questions beacon and scuff search - leave clues in place - relay information - acknowledge Bring your gear A,B,C’s, turn off transceiver and look for other victims Secondary Survey -1st Aid and evacuate if necessary Report the avalanche Two Person Group Go or no go Survey the avalanche for clues Turn to receive and begin beacon/scuff search Bring your gear A,B,C’s Secondary survey - 1st Aid and evacuate if necessary Report the avalanche - local SAR- www.avalanche.org Rescue - responsibilities

Beacon Search • Primary: Search patterns before obtaining a signal • Communicate findings to leader-”I have a signal!” Leader- acknowledge back. • Bring your gear with you - a probe and shovel are no good at the top of the slope
Signal strength depends upon orientation maximum Colorado Avalanche Information Center
Signal strength depends upon orientation When the receiving unit is 90º to the sending unit’s field, the signal strength will be at a minimum for that location. minimum Colorado Avalanche Information Center
Signal in X axis depends on Orientation The “Fountain” will give 2 low numbers When the receiving unit is 90º to the sending unit’s field, the signal strength will be at a minimum for that location. Colorado Avalanche Information Center
Signal in X axis depends on Orientation The “Rainbow” will give 1 low number When the receiving unit is 90º to the sending unit’s field, the signal strength will be at a minimum for that location. Colorado Avalanche Information Center
Pinpoint search: Be Consistent with Orientation Go slow to Go Fast Is it a Rainbow or a Fountain?
PROBING • Know how to put probe together, • Probe “slope normal”, be methodical • Be gentle- you are probing for people not crevasses • SPOT PROBING for likely burial spots Upside of trees and rocks Benches in the track and runout zone Toe of debris Outside of curves in the track In line with surface clues • If you make contact, leave probe in place and throw snow downhill. The deeper the burial, the bigger the hole needs to be.
Recovery and Evacuation • Priority for recovered victims - ABC's and hypothermia - Find other victims - continue patient care/evacuation - will you need outside assistance? • report the incident to local search and rescue and www.avalanche.org
