NEST TRIP REPORT Alexander�s Trip Report 10 Jan 98 The NEST, Northeast Sump Exploration Team, returned and continued its exploratory work in Alexander�s Cave on 10 Jan 1998. NEST is a formally recognized Project of the NSS and consists of a team of sump divers and dedicated support personnel who are pursuing original exploration efforts at several caves in the PA Virginia and West Virginia areas. The team surveys and further documents these sites through the use of still and video techniques as well as engaging in biological surveys and water sampling at these locations. NEST is also available to support the NCRC in situations involving flooded passages and beyond sump rescues. Below is an account of the Teams most recent explorations. Eric Tesanu waded into the head pool of Sump J2 and carefully felt around for the dog spike that served as the first under water tie off for the line that runs into this sump. The water levels in this pool where over one foot higher than I had ever seen them before and the visibility was a foot or less. After a bit of effort Eric was able to locate the spike and we took our final survey shot of the day. This last 12 foot shot took us over the 400 ft mark and tied together a section of survey which had been located at each end through the use of a cave radio system on an earlier trip. The area of the cave that we were working in was a dry section of passage that lies between sump J1 which is 350ft long and sump J2 which is approximately 150 ft long. Beyond sump J2 are several hundred feet of addition dry passage and Sump J3 which has not been pushed. Over the last year we had been methodically exploring and surveying this section of cave as part of a Bald Eagle Grotto project headed up by Dave Holick as over all project coordinator and Bob Zimmerman as the cartographer to remap and further push Alexander�s cave. With our last shot completed we gathered up the survey gear and began the trip back to our sidemounts. The passage started out as a 20 by 7 foot high flat floored walking section with a bare dark colored limestone floor. The floor itself in this area was very unique in that a single long groove about half an inch deep and one inch wide ran down the middle and was crossed at right angles by other similar grooves. These were further supplemented by groves that also ran at a 45 degree angle to the primary crossing ones that were in turn parallel to each other. The whole effect as Eric noted was that of a giant herring bone over 40 ft long. We stopped for a moment to ponder what could have caused this interesting configuration before continuing down the passage which rapidly became a low hands and knees muddy crawlway with a high water overflow stream meandering down the middle. We soon reached our gear and took advantage of a small waterfall that exited out of the ceiling to wash most of the mud off our drysuits before donning our sidemounts and proceeding into the pool that leads to sump J1. Under normal condition one has to perform a climb down to reach the pool. The water levels were so high that sitting down and floating was all that was required to enter. After donning my fins and doing a regulator check I floated in the pool while Eric completed his preparations. As I did so my mind drifted back to the beginning of the days activities. The three hour ride to the cave had a been a pleasant one and unseasonably warm for this time of the year. As we got closer to the cave we noted that all of the water levels in the rivers and creeks were up several feet above normal levels . The water levels in the cave mirrored this with the run from J1 dumping large amounts of water into the main river passage. Visibility appeared to be one to two feet. Dave Nicholas had geared up first and performed a recon and orientation dive to the major restriction 50 feet into J1. He observed that although the vis remained marginal the site was still diveable. I took a quick look myself and noted that the higher flow was quickly pushing the sediment out that entry to this area inevitably stirs up and we decided to press on with out plan to put a two man team on the other side to survey the dry section. By this point Eric had finished suiting up and joined me. He entered first carrying the tape measure and I followed with the rest of the survey gear in a half gallon nalogene bottle. The swim in proved to be uneventful with visibility remaining a comfortable one foot most of the way. The only question now was what the exit would be like. When Eric completed his checks we discussed our dive plan. He would enter first and I would follow at a 3 minute interval. We reminded each other that if we experience any problems the survey gear would be jettisoned to be recovered at a later time. As the light from Eric�s Aul Meteor four vanished from sight I found myself alone in the chamber, the only sound being that of the waterfall and my own breathing, the minutes seemed to crawl by. At the appointed time I did a final reg check and submerged and entered the sump. For the first 5 feet I could actual see the line and then things went to absolute zero. The next 250 feet I spent carefully following the line from tie of to tie off, and negotiating around the limestone protrusions that reached out to block my progress. The feeling of the survey knots passing through my right hand and the dog spikes at regular intervals being the only reference to my progress. As I neared the restriction the visibility opened up to six inches and I could actually see the line. It is amazing how much six inches of vis is after an extended period of absolute zero. As I enter the restriction I could feel the cave gently in contact both above and below me and I gently wiggled out into the room beyond. After a further 50 foot swim I surfaced to find Eric, Dave Nicholas and Bill Scheely waiting for our return and we began the process of packing out our gear to the surface. It had been another successful operation for the team. Dave Nicholas had been able to get in another orientation dive in preparation for passing the restriction at J1 and Eric and I had been able to add over 400 ft of survey to the cave in the B survey. Once again we would like to recognize our sponsors and all of the supporting cavers who helped make our efforts possible. A special thanks to Arnold Jackson Of American Underwater Lighting who supplied our exceptional primary lights, meteor 4�s, and Jon Breazile who has provided us with other vital support. A special thanks also go to Bill Sheely, the support team leader who personally made over 10 trips to the surface hauling gear in and out of the cave as well as those folks listed below who also assisted our efforts.
