Nittany Valley
Nittany Valley is in the western part of the Ridge and Valley province of the Appalachian Mountains. During the Appalachian orogeny, the sedimentary rock layers folded up into the Nittany Arch anticline. The arch was an ancient Himalayan scale mountain that towered above what is now the valley. The oldest rock layers from deep within the eroded mountain are now exposed on Sand Ridge in the middle of the valley. Younger rocks from the outer layers of the arch are exposed on the west side of the Bald Eagle Mountain ridge in the Bald Eagle Valley, with the youngest across that valley at the foot of the Allegheny Front. The Nittany Valley, formed in the area where the mountain once stood, is an example of inverse topography.
