When I was leading groups into the Wyoming wilderness in the 1990s, once we left a trailhead, we were on our own.
If somebody got hurt, we could walk or carry the injured person out or send runners to the road to call for support. In the case of a life- or limb-threatening emergency, we could use a transponder to try to send a coded message to a passing aircraft, pleading for help.
Things have definitely changed.
“People expect to be rescued,” said Tod Schimelfenig, who has been on the search and rescue team for Fremont County, Wyoming, since the 1970s. “Maybe it’s that a whole generation has grown up with instant communication, and that drives what they do when they go into the wilderness.”
What they do, according to Schimelfenig, is go farther and attempt more difficult objectives, which means demands on search and rescue teams have increased sharply over the last decade.
The United States has a patchwork of search and rescue organizations charged with responding to backcountry emergencies. Who comes to your aid depends on where you are and what land management agency is responsible. Most have volunteer teams that report to a local law enforcement officer, although some national parks, like Yosemite or Grand Teton, have paid crews on call.
