## Geology

Colerain valley (shown as "Friends Cove" on topographic maps) is an anticlinal valley, with Evitts Mountain and Tussey Mountain forming the limbs. The Silurian Tuscarora Formation, a hard sandstone, outcrops at the crests of the ridges and is stratigraphically higher and thus younger than the rest of the bedrock in the valley. The low knobs or "benches" on the northwest side of Tussey Mountain and the southeast side of Evitts Mountain are formed by the Ordovician Bald Eagle Formation, another sandstone, that is stratigraphically below the Tuscarora. The rock formations in the valley range from Ordovician shales and limestones to the Cambrian Warrior Formation, another sandstone. The limestones can form sinkholes.
