Quick Facts

Scenic View/Photo Spot

The Uinta Mountains, a spur of the Rocky Mountains, were formed by compression of the Earth’s crust. Once level layers, they then buckled upward into a broad arch. The range is highest in north-central Utah and gradually flattens out east of here. This uplifting probably began about the time the dinosaurs went extinct, and most likely continued a little at a time over millions of years. Even as the land rose, it was being worn down by erosion. Many of the younger rock layers have been stripped off to reveal these ancient rocks that were once at the very core of the mountains.
