Dinosaur National Monument - Split Mountain

This view from the end of the Petroglyph Trail shows the high, rugged core of the Split Mountain. Split Mountain is a great anticlinal fold. The mountain gets its name because the Green River cuts through the mountain rather the flowing around it. The entrenchment by the Green and Yampa Rivers has exposed the colossal geologic structures associated with the Laramide orogeny, and the thick sequence of pre-Laramide rock formations.
