About Sinnett-Thorn
The Sinnett-Thorn Mountain Cave System is a complex cave system in Pendleton County, WV which is not only a National Natural Landmark but is also an important nursery and hibernaculum for endangered bat species. Access is managed by the Sinnett-Thorn Cave Conservancy (STCC) which is a committee of the Potomac Speleological Club (PSC). The cave system is on private property and the entrances are protected by bat-friendly, locked gates. The property is posted against trespassing and nobody is allowed to enter the property unless given written permission from STCC.
To access the cave system use the information and resources on this site to learn how to contact STCC and request access.
THE CAVES ARE CURRENTLY CLOSED
Due to White Nose Syndrome caving trips are restricted. As of 1/24/2023 cavers will be able to access the caves for 2 weeks in the spring of 2023. Dates are yet to be determined but will be posted here as soon as we find out. Access dates are dependant on the weather which affects when bats come out of hibernation and before the cave is used as a nursery. We need to try to hit that period in between.
If the West Virginia Department of Natural Resources bat counts show a decrease in populations, access to the cave will be curtailed or eliminated. It’s up to us cavers to keep the numbers as high as possible. Go here to learn about mitigating disturbance to hibernating bats.
