The Blue Ridge Railroad was hoping to bore through Stumphouse Mountain for a line extending from Anderson, South Carolina to Knoxville, Tennesee. Started in the early 1850s, 1,500 Irish miners cut through blue granite with hand drills, hammers and chisels, and black powder in this and two nearby tunnels. Their efforts came to an end in 1859 when no more funding could be procured to complete the work and subsequent efforts to restart the rail project over the next several decades failed.
Even though the ceiling was quite high, 20 or 25 feet ( 6 or 7 meters) right here, I’m not a fan of underground spaces and stayed pretty close to the entrance. Ted was a bit more adventurous. You can go further, but would want better shoes and light, be prepared for bats, and have water protection for your camera.
There was less green growth on the walls just a short distance from the entrance. Two streams of water a few inches deep flowed on either side of the floor and water dripped from the ceiling. The cool air flowing out of the tunnel was welcome on this hot day.
Stumphouse Tunnel is managed by the City of Walhalla, SC as part of a recreation area.
