Fossil Butte National Monument is a 4 mile loop trail located near Cokeville, WY. The trail is good for all skill levels and primarily used for hiking.
This trail loops around with some points of interest posted along the way explaining how the water used to attract ancient wildlife around the lake shore and left evidence behind buried that is currently being excavated. The dinosaur bones are on exhibit in the visitor center. I found this center very tiny and the trail is extremely boring. It is also very isolated from any civilization. I did see pronghorn along the road.
Good training trail. Some interesting historical sites. Rocky, elevation climb. Wildlife.
