Wheeler Geologic Area

The Wheeler Geologic Area is found within the La Garita Wilderness. Once named a national monument the area lost that designation but is now protected as a special geologic area within the wilderness area. The rock is a welded rhyolite tuff formed during the formation of the San Luis caldera, one of many explosive volcanic remains in the San Juan Mountains.

The geologic area is at the end of a 7 mile hike. The trail crosses some incredible meadows with views in all directions. I would not want to be caught in a lightning storm out there! The geologic area is eroding out of a hill side and shows all of the usual hoodoos, pinnacles and towers. It appears that the tuff in this area is not quite as welded as in other places giving rise to these great eroded remnants.
