Rock House – Hocking Hills Ohio
Rock House is unique in the Hocking Hills region, as it is the only true cave in the park. It is a tunnel-like corridor situated midway up a 150-foot cliff of Blackhand sandstone. Rock House has a ceiling 25 feet high while the main corridor is 200 feet long and 20 to 30 feet wide. The cavern was eroded out of the middle zone of the Blackhand sandstone. The resistant upper zone forms the roof and the lower zone forms the floor. Water leaking through a horizontal joint running parallel to the cliff face caused the hollowing of the corridor. Rock House was used by Native Americans for turpentine stills, by pioneers for animal shelter, and even by criminals for a hideout, the area has a colorful history with carvings in the sandstone that date back to the 1800’s.
