This shows the bear flares that we used to protect our camps. We put a stake in the snow at each corner and then strapped a bracket with a crampon strap to the stake. The bracket had a hole drilled through, in which the bare flare sat. A pin restrains a hammer from setting off the flare. Each pin has a karabiner clipped to it, through which we ran a fishing line. If the fishing line is disturbed, it pulls the pin out which set the flare off.
