Carbon monoxide, an odorless, colorless, and poisonous gas, can build up to dangerous levels inside a tent during or after cooking with a stove. Sharp End hostess Ashley Saupe had a personal scare with CO poisoning, and in Episode 47 she discusses her own experience and other people's close calls with Denali mountaineering ranger Dave Weber. This episode is packed with essential information for winter mountaineers or anyone else who camps in snowy conditions. Don't miss it!
