Having become distracted by other easier options near the Main Hell Hole I made my own exploration while the others enjoyed the conversation in the forest above.
I took this somewhat "evil" portrait holding Greg's maglight in a narrow crevice that led down to an ice cave. It looks like porcupines live down here and the crawl was one of unimaginable filth.
The enticement to find cave passages beneath the Hell Hole's crazy, rock-strewn terrain is strong. This particular cavity was quite promising. It runs in a joint system that is marked on the surface by a number of linearly oriented depressions. In this area it soon becomes apparent that the joints of the upper bedding planes run in opposition to those in lower layers. To track the possible run of tunnels beneath the surface becomes quite confusing as they usually jog off in unpredictable directions. There also seems to be a tendency to have cavities that undercut the walls of good thick strata.
