The Casper Times reports Jim Ratz, 52, former executive director of the National Outdoor Leadership School and co-owner of the Jackson Hole Mountain Guides, was died while rapelling Sinks Canyon across from the Sawmill Campground on Highway 131 near his home in Lander, Wyoming.
Ratz was executive director of NOLS from 1984 to 1995, and was the founding chairman of the Leave No Trace program, which developed strategies for minimum impact in the backcountry.
Jackson Hole is the definitive guide service for Gannett and Granite.
