I have posted the contents of the Schoolhouse Cave register on the PSC website. The url is...

The register is under "Trip Reports and Discussions" and then "Trip Reports."
The book was retrieved from the cave on September 24th by Gordon Brace, Paul Gillis, and Mike Frisina. I (George Dasher) transcribed the thing in November. The book is 4 by 7 inches in size, and is in TERRIBLE shape. It has a bad smell and working with it has left a bad taste in my mouth. A large portion of it is totally unreadable. Most of the trips are from the mid-1970s.
Schoolhouse Cave is located in Pendleton County's Germany Valley. This is West Virginia. It is one of the caves where the NSS has the oldest history of exploration, and the cave was first entirely explored by a local mountaineering club. Few caves in this country have received the literary attention of Schoolhouse and nearby Hellhole, and Schoolhouse was for a long time considered the "toughest" cave in the United States. Even today, it dominates the NSS Photo archieves, and it is the cave where the NSS familar half circle logo originated.
The cave is about one mile long and about 400 feet deep. It is closed year round because of endangered bats (plus the landowners don't want people in the cave), and has only been opened briefly in the fall for survey trips. The cave is also one of the oldest saltpeter caves in West Virginia (perhaps the second oldest) and may be the only cave in the state that was mined by the North during the American Civil War.
