In the mid-60s Maxwelton Sink Cave was dug open and then explored and surveyed by the Pittsburgh, Boston, and Philly Grottos of the NSS. The entrance was notorious for silting shut, so the whole 10 miles of cave was surveyed in just a few years before it was totally silted shut from Hurricane Camille in 1969. Maxwelton Sink Cave, in Greenbrier County, West Virginia, is a large contact cave and belongs to the group that includes such caves as McClungs (which it is now connected to), The Hole, Ludingtons, and Culverson Creek.

A new entrance was dug open and the resurvey of Maxwelton Sink Cave commenced in February 2004. In the early stages of the project, most of the work being done was resurvey, but as the map began to fill out, it became obvious that there was a lot of potential for new cave. It wasn’t until later in the project that more and more new passage was found. In addition to the large extension of Sweetwater, there were a number of finds in such places as Thunder Dome, Consent Canyon, and Classic Canyon. Plus, there were numerous other small extensions that added to the overall length of the cave. Over 4 miles of new cave have been added to the “historic” section of Maxwelton Sink Cave, plus 10 miles have been added via the Sweetwater extension, which makes Maxwelton Sink Cave 24.1 miles long. Of course, Maxwelton Sink Cave is now just a part of the Great Savannah Cave System, which is 42.3 miles long. But better yet, in addition to the Sweetwater extension, the classic section Maxwelton Sink cave is still growing—new cave is being found. Who knows what the future will bring?
