This view is looking north from the visitor information kiosk/picnic area at the Painted Hills Unit. The hill (about 500 feet high) is called Carroll Rim and was the source of many fossils early in the exploration of the John Day region. The Picture Gorge Ignimbrite (a massive volcanic tuff deposit) caps the hill (technically called a cuesta). This massive volcanic deposit overlies sedimentary beds of the middle Turtle Cove Member of the John Day Formation.
