Heading south from Frenchglen, you'll soon pass the turnoff for the Hart Mountain National Antelope Refuge. This primitive road leads to the 275,000 acres of high-desert habitat that was set aside in 1936 to provide spring, summer and fall range for the region's pronghorn antelope herds. Continuing south, Route 205 parallels Catlow Rim (number 6) and Catlow Valley, home to some of the region's wild horse herds and big horn sheep which can frequently be seen from the road.
