[trip] New Deckers Creek Cave Survey

This Sunday, John Harman, John Cunningham, and I (Dave Riggs) surveyed the new cave near Deckers Creek. We spent about 3 hours surveying, shot 11 shots, including two surface shots in the entrance sink. The cave is 65 feet long and 27 feet deep; the total slope length of our in-cave survey was 99.5 feet. This was John C's first survey trip, and he did great - they didn't have to re-shoot a single shot. It was my first time doing a real sketch, and I can't say that I did as well as the instrument readers - I'm going back next Sunday with a lineplot to re-do my sketch properly!

John C. chimneyed up to the very top of the crevice passage and found that it goes to the very top of the limestone, there is literally topsoil at the ceiling. We moved a few rocks and opened up a second "entrance" to the cave, a 9 inch wide and high joint which intersects the top of the crevice passage. It was large enough to survey through for a single closed loop, but you'd have to be seriously determined to actually go into the cave that way.

Working names for the cave are "One Room Wonder" and "Three Turkeys", the latter name being a double-play on the three wild turkeys that tried to scoop our cave that afternoon, and on the "three turkeys" who surveyed it.

Another New Deckers Creek Cave

I went on a lazy afternoon hike along Deckers Creek this afternoon and located a promising area with a dry streambed that cuts entirely through the thickness of the Greenbrier. With very little effort, I discovered a new cave located up the bank in a narrow, 8-foot deep sink walled by an outcropping of the upper Wymps Gap member. An opening leads down into an entrance room, which is about 8 feet in diameter and 6 - 8 feet high. A fissure passage leads off for about 15 feet and then rounds a turn, beyond which I did not explore (I was armed with nothing but a small pocket light). This area needs to be ridge walked, as it has potential.

Edit: I re-visited this new cave to GPS it, and snapped a few photos. The cave appears to be formed along enlarged vertical joints that combine to form the room at the entrance. The entrance room is about 12 feet at its highest point, with a low lead, about 2 feet high, on the right side. The left side is a fissure passage, up to 15 feet high or higher, and up to 4 feet wide, which goes back for about 15 feet and then appears too tight to follow. The fissure passage bells out at the bottom, and there may be more passage down at that level. The strata looks very similar to that visible in Nuttinbuttawett Pit, which is also formed in the uppermost parts of the Greenbrier; limestone beds are varying shades of grey, blue, and tan, with several containing nice fossils, and a thin layer of tan shale which easily weathers away.

The low lead heads off under the entrance from the Entrance Room. It is about 2 feet high, and not as narrow as it appears in this photo.

[trip] WVUSG Does Pendleton County

The WVU Student Grotto recently spent a great weekend in Pendleton County. We stayed at John Harman's WV Underground fieldhouse in Germany Valley, had an excellent time and even managed to do a bit of caving while we were there.

On Saturday morning, we took a trip to Sinnett-Thorn. Since we had a fairly large group, including many "green" cavers, we moved rather slowly. We headed back in through the main canyon passage, went up The Silo, and checked out the big room while we ate lunch. We examined the Thorn connection, but the passage had 6 inches of water in it - the wind howled through the passage so forcefully that the water had continuous waves on the surface! Opting to stay dry, we headed back down The Silo and went upstream to the waterfall. A few people poked around up top and did the squeeze, finding borehole passage beyond, while everyone else monkeyed around near the waterfall. We spent about 5 hours in the cave.

While we were in Sinnett-Thorn, Kyle McMillan led a group of beginners from Alderson-Broaddus into Trout Cave, on the John Guilday Caves Nature Preserve.

After eating some dinner in Franklin, we headed to Harper's Pit, a 70' deep pit located in the middle of a Germany Valley field. Kyle and I belayed people from below; Tom Lilly, Jataya Taylor, Dave Mason, Gayle Suppa, and Thad Martin did their first in-cave rappels - everyone did a great job!

On Saturday morning, we all had a serious hunger for some pie, so we headed to the restaurant at Seneca Caverns. Unfortunately Thad's car died on the way there, so he and a few other people spent the remainder of the day trying to fix it. Meanwhile, the rest of us headed to nearby Mystic Cave. We first went down the right-hand (downstream) branch of the cave, did the handline climb down and went to what seemed like the end, then came back out to warm up and have a bite to eat. After narrowly avoiding a territorial bull, we headed back in and went upstream, getting thoroughly soaked in the waist-deep pools, but enjoying the amazing formations. For such a frequently-visited cave, Mystic is very well decorated, and is a great horizontal (but wet) trip. We probably spent a total of 4.5 hours in the cave.

[trip] NCRC Orientation to Cave Rescue Class

This weekend I attended the Orientation to Cave Rescue class which was offered by the Eastern Region of the National Cave Rescue Commission (NCRC) at Laurel Caverns, PA.

We met at 8:00AM on Saturday morning at Laurel Caverns. The morning was spent in a classroom over a powerpoint presentation on the basics of cave rescue - command hierarchy, responsibilities, goals, etc. Several search-and-rescue teams were conducting a mock-search during our training. After a brief non-vegetarian lunch, we broke out into smaller groups and did some more hands-on training. One session showed us how to use military field telephones (fun!); one gave an extremely high-level wilderness first-aid lesson - too basic to help those with actual EMS training, too vague to help those without. A third session taught us how to package a patient in a SKED and a Ferno stretcher. We had a nice vegetarian dinner, then broke into two teams and did a rescue "obstacle course", where we would package a patient and then maneuver them (gently!) over, under, around, and through all sorts of constrictions, drop-offs, tunnels, and other brutal obstacles that simulated cave terrain. This was a lot of fun, but was extremely exhausting after 2.5 hours. We finished up around 8:00PM.

Again, we met at 8:00AM at Laurel Caverns, but Sunday was much different than the previous day's course. We arrived and were incorporated into the previous day's mock-search, which had now turned into a mock-rescue. In conjunction with the search-and-rescue teams, we reported to Barton Cave, where three cavers were suspected as being "lost". Since I am familiar with Barton, I was put on the initial search team as a guide. Our team went in to the back of the cave, where we quickly found the first "lost" patient (who really enjoyed playing the part of a lost old caver). After getting our patient out, we were sent back in to help extract an injured patient who was currently being packaged. It took about 4 hours to extract him, even though he was only a few hundred feet from the cave entrance, and it looked like quite an unpleasant ride.

I learned a great deal about how cave rescues operate and about how I can most effectively and efficiently help out. The most striking lesson of the weekend is how long it takes and how much effort is involved in extracting an injured caver - it will make me re-evaluate the sorts of risks that I take underground for sure! I had a great time taking the course, and I highly recommend it to all cavers.
