Denali mountaineering ranger and flight medic Dave Weber returns to the Sharp End to discuss the ins and outs of calling for a rescue: when to do it (and when not to), how to make the call and what to say, and how to prepare for a helicopter rescue.

The Sharp End is presented by Mammut, with additional support from Colorado Outward Bound School and Suunto. This podcast is produced by the American Alpine Club.
