I know about the Philadelphia Grotto adding some passage with their dig that made the stream level accessible where you go through that long crawl (dug out by the Philly Grotto) and then down the several drops to this huge pile of mud where it intersects the stream level which continues in both directions. It's possible that the Philadelphia Grotto may have surveyed to this point but I doubt that they surveyed any of the stream passage because the dimensions of the stream passage are very small and it would be even more difficult trying to measure the stream passage with survey gear. And I have the McAllisterville map that shows 2,332 feet but it seems to me that a large portion of the cave on the map is missing.
