Entrance Portal Interpretive Site

Entrance Portal Interpretive Site sits along the Bighorn Scenic Byway just as you enter the forest.

Syncline Thrust Fault

Across the road is a thrust fault/syncline formation, exposed by the road cut. The fault occurred when pressure caused the rock layers to push up creating the non-conforming layers and downward fold (syncline).  The Bighorn Mountains reached their highest elevation about 60 million years ago.  Uplift of the area by movement of the Earth’s crust caused this folding.
