Outcrop along the Notom-Bullfrog Road

This view is looking south along the strike of the Waterpocket Fold from the top of a sandstone outcrop within the Morrison Formation (Jurassic age) along the Notom-Bullfrog Road. A forest of junipers and pinyon pines thrives on soil formed on ancient volcanic ash and sand derived from the Morrison Formation. The ridge of sandstone on the left is the Lower Cretaceous Dakota Sandstone. The white hogback ridge on the right is Navajo Sandstone.
