Hitch a ride with 60 Minutes correspondent Bill Whitaker along the Green River Drift, the longest running cattle drive in the U.S.

Upper Green River Valley, Wyoming

Predating most federal land management agencies, the Green River Drift cattle trail has been continuously used since the 1890s by the Upper Green River Cattle Association ranchers to get cattle from spring pasture on the desert to summer pasture in the forest. Chilly fall weather causes the cattle to “drift” back out of the forest to return to their home ranches. The trail, 58 miles long with 41 miles of spurs, crosses BLM, State of Wyoming, National Forest, and private properties.
