NEST TRIP REPORT Buchanan Cave 4 Nov 2000 The Northeast Sump Exploration Team, NEST, conducted exploration efforts In Buchanan Cave Resurgence in Virginia on 4 Nov 2000. 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 passage and beyond sump rescues. Below is an account of the Teams most recent explorations. I pulled up to the spring after a 7 hour ride and stretched out the kinks. It had turned into another beautiful day with the low clear flow emanating from the head pool promising good visibility. I had my gear preparations down to a well choreographed process and despite having to maneuver around some curious cows 40 minutes later I finned into the first sump wearing my OMS 45 side mounts. I also carried a stage cluster consisting of another OMS 45 and an alum 30 clipped together. Both stages were equipped with flotation cells to reduce their negative buoyancy and improve their trim characteristics. For the first 300 feet the first sump was a nippy 48 degrees with its normal 6 inches of visibility. After making a 90 degree turn to the left at a depth of 32 feet I followed the line up slope and above the thermal cline. At this point the water warmed up to a balmy 52 degrees and vis opened up to 20 feet. Once again I was in sump diving nirvana. At a penetration of 600 feet, about 100 feet into the beginning of the second sump, I parked on the ceiling and dropped my Alum 30 stage, switched over to the 45 and continued through sumps 2, 3 and 4. I surfaced at the beginning of the dry cave 1100 feet in and 23 minutes after I had left the entrance pool. On my first push to this point I had felt like I was at the end of the world, today I felt right at home. Before me lay 150 feet of relatively flat if somewhat slippery walking trunk passage. I negotiated it in one trip, donned my fins and was on my way into the 5 th sump within 6 minutes. The walk through the dry cave had warmed me up nicely and the 52 degree water once again felt comfortable. I finned into a broad 15 foot wide passage that averaged a little over 3 feet high and which gradual increased in height as I continued forward following the line that I had laid on my last push. About 100 feet in I retrieved my large exploration reel from the silt and continued laying line belaying it with Disler Spikes every 20 to 40 feet. The passage maintained it dimensions as it gradually meandered back and forth gradually heading deeper. The line spun off my reel at a pleasant clip and 200 feet in I had reached a depth of 51 feet. I had been hoping this would not be another deep sump but this was not going to be the case. As I finned forward it finally appeared to bottom out and began a gradual upward climb. I turned the dive at a depth of 48 feet with a total penetration of approx 320 feet and headed back out verifying my line placement as I went. After surfacing in the head pool I pulled my fins off, walked ashore and lowered my tanks. It was time for a surface interval before I continued and a closer look at the dry side lead that headed off on the left side of the passage next to the sump 4 head pool. This lead was also walking size and climbed at a steep angle over a mixed sand and flowstone slope. I had to use a lone piece of break down as a climbing aid to negotiate one of the steeper parts of this passage. The sand showed no signs of foot prints even above the flood zone so once again it appeared I was the first person to ever pass through this section. As I moved forward I notice several small dry rimstone pools one of which contained an incredibly beautiful pure white crystal formation that hugged the edge below the rim. I paused to admire this for a few minutes before continuing my climb up the steep slope. The nature of the passage again changed and I soon found myself standing at the bottom of a 10 foot high dome with a second low oval passage heading off from this back down to the river level toward the head pool of the fifth sump. I opted to follow the continuation of the passage that continued up slope and soon found my self in what appeared to be a mud lined dry stream run. It turned out to be rather moist a few feet further and I was soon wallowing in thick gooey mud up to my knees. I was able to use a spike that I brought along as a climbing aid and pulled my self out on to a sandy slope on the left. The passage had now become crawlway size and appeared to make a hard turn to the right. By now I was breathing rather heavily from my exertion and decided that this was not the best option during a surface interval. Leaving the crawlway for another day I backed up and returned to explore the second downward sloping passage which in fact did connect with the main trunk. Concerned that I might damage the cave or my dry suit I opted not to slide down the final steep section and retraced my steps to the rim stone pools, pulled up a flat section of cave, shut my light down and relaxed while my body temperature returned to normal. After an hour I headed back to the upstream pool and washed of the worst of the mud from my DUI, then collected my gear and began my exit. After a pleasant but some what chilly dive I emerged back on the surface. All in all another highly productive day at the site with the line pushed to well over 1600 feet from the entrance, not bad for a Virginia sump. Once again I could not wait to return to see where sump 5 would lead me. 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 HIDs , as well as other critical gear and Tom and Jon of the Fifth Dimension Dive Center who has provided us with other vital support. We would also like to thank Terry Brady, of the Brass Anchor who has provided us with generous audio visual support. Additional sponsors include Lamar Hires of Dive Rite, Alex Sproul of Inner Mountain Outfitters, Adrew Kipe of Maryland Reproductions, and Robert Carmichael of Brownies Third Lung and HALCYON, The Doing It Right Equipment Company, and our most recent sponsor, DUI for our outstanding CF 200 series Dry Suits, Tim Walker, Hank and Jane Anderson, and the Sovik and Mothes families without whose support none of our efforts would have been possible.
