Use this list of survival essentials compiled by North Shore Search and Rescue and the BC Federation of Mountain Clubs.
Map
Compass – Even if you carrying a GPS, it is essential that you can navigate using a map and compass.
Water
Extra Food
Extra Clothes
First-Aid Kit – The size of the kit will depend on the number of people in your party, the length of the trip, and the remoteness and level of risk you plan to engage in. Remember to restock items in your kit and to check the condition of the contents and any expiration dates.
Knife
Headlamp/Flashlight – With spare bulbs and batteries.
Whistle – A whistle attracts attention, can be heard over long distances, and is more sustainable than shouting for help. Three blasts is a standard distress signal.
Waterproof Matches/Lighter
Firestarter/Candle Lantern
Large Orange Plastic Bag – One of the most valuable items on the list. Crawl into the bag to keep warm and dry. The orange colour is highly visible and helps attract attention, particularly from the air.
