Visitors on route along US HWY 189 and on Highway 352 have an opportunity to see a part of our authentic, old west heritage, the Green River Drift Cattle Drive. Twice a year, in early spring (around June 13th this year) cowboys move cattle from their winter cattle allotments from the Bridger-Teton National Forest in the Upper Green back home to their ranches to summer.  The Historic Green River Drift has been used since 1896 and is still in use today as part of cattle operations for ranchers in the Upper Green River Valley. It is 58 miles long and has 41 miles of spur trails. For 115 years, it has been used by ranchers to get their cattle to and from cattle range allotments in the Bridger-Teton National Forest in the Upper Green. The lower end of the Drift crosses the Mesa and the upper end of the Drift roughly follows Highway 352 north of Cora to the forest boundary. The cattle sorting grounds for the Drift are located near Trappers Point Wildlife Overpass, at the junction at US 191/Hwy 352 a few miles west of Pinedale.
