City of Rocks (Cassia County, Idaho)

Continuing on down the road from Castle Rocks, we enter the City of Rocks National Reserve, also made popular by climbers. Much like Castle Rocks, this area is littered with granite islands jutting up from the landscape. With peculiar names like Elephant Rock and Devil's Crack, this area is a mecca for climbers, of which many are here today. In addition to the rock formations themselves, early pioneers wrote their names in axle grease on the granite. It's interesting to see this early form of graffiti.
