Tytoona Cave, Limestone cave in Sinking Valley, Blair County, US.
Tytoona Cave is a limestone cave in Sinking Valley where the entrance opens into a large passage within a sinkhole. An underground stream flows through the system, shaping its character.
The cave first appeared in written records in 1788 when a magazine published details about its entrance and features. This early documentation marked the beginning of scientific attention to the site.
Local stories from the 1750s describe Bedford Rangers pursuing people into the cave, where they vanished without explanation. These narratives continue to shape how visitors understand the place as holding mystery and intrigue.
Access to the initial sections is available daily, but sturdy water-resistant footwear and multiple light sources are necessary for safety. The damp environment requires careful footing.
The underground stream flowing through the cave continues beneath the surface and resurfaces more than a mile away at Arch Spring. This hidden water system connects two separate surface points.
