Two Locks Caves, Washington County
Geology:
Two Locks Caves are in the Beekmantown Limestone that strikes N. 30º E. and dips 80º E. and are developed along the bedding planes.

Description:
Several small caves and solution holes are developed in the bluffs along the C & O Canal, south of Two Locks. The northernmost cave is a 4-foot square opening in the cliff face, 20 feet above the river. It consists of a single room 10 feet in diameter and 5 feet high and is used as a roost by numerous pigeons. One hundred feet south of here is a fissure which extends south for 30 feet. The entrance to the largest cave is 150 feet to the south, in a small hollow 30 feet above the river. It trends northeast as a crawlway for 40 feet before opening into a somewhat higher passage with two side passages. These extend for short distances on both sides of the entrance passage as low crawlways.
