Construction on the railway was begun in the late 1850s and was successful through most of South Carolina until hitting the mountains around Wallhalla in Oconee County.
[4] Construction on Stumphouse tunnel began in 1856 when the George Collyer Company of London brought many Irish workers into the area for this project.
[5][6] Today, where the tunnel was meant to end on the other side of the mountain, there remains a mound of earth (intended for the railway tracks) submerged during the summer months under Crystal Lake, located just west of Highway 28.
In 1999 this vent was impacted by a rock slide, however in 2000 the town of Walhalla re-excavated the tunnel and safely returned it to public use.
After a developer attempted to purchase the property from the City of Walhalla in 2007, Naturaland Trust, a conservation agency created by C. Thomas Wyche, pledged about $2 million to protect the surrounding property; and a consortium of non-profit conservation groups, private individuals, and the state of South Carolina provided the money and resources to preserve the mountain for public use.
