NEST TRIP REPORT Buchanan Cave 13 Jan 2001 The Northeast Sump Exploration Team, NEST, conducted exploration efforts In Buchanan Cave Resurgence in Virginia on 13 Jan 2001. 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. We set out early Saturday mourning from Paul�s home and our reward for an early start was a thick layer of ground fog as we headed south to the spring. As we topped the mountain that separates the valley from the rest of civilization we broke through this layer and met the rising sun on the other side. Below us a thick bank of clouds bathe in brilliant sunlight filled the valley. In one or two spots small hills poked above this layer like isolated islands in a great inland sea. We wound our way along the switch backs on the other side of the ridge line enjoying this spectacular view before plunging back into the soup and completing the ride to the cave. The sump gods were once again smiling on us for on our arrival we found the run was low and clear. This was Dave�s first visit to the site so we walked to the entrance and discussed the line location and the best way to enter the pool and the sump. The head pool which is reached after a short crawl, is 20 by 20 feet in size with a limestone ceiling 5 to 6 feet above it. Over most of its area it is only five inches deep so you almost have to enter the overhead to perform your reg checks. After thoroughly discussing dive and contingency plans we broke out and assembled the gear while the local herd of cows looked on. While I stood by as a support diver Dave entered the pool and I watched the beam from his AUL HID slowly disappear from sight, the sound as the last of his bubbles gurgled out with their corresponding echoes reverberating off the surrounding limestone walls provided a fitting touch to his departure. I walked back to the vehicle and began the final checks of my equipment. My gear was ready to go and I had timed my preparations so that I would be able to enter the sump to find Dave if he failed to appear at the appointed time or begin my push when he did return. He surfaced right on que with a massive grin on his face. Although the vis in the first part of sump one is no more than a foot he was still a happy camper. He was the third diver to ever enter the site. After a final review of the exploration plan I entered next carrying a double stage consisting of a buoyancy compensated Alum 30 and OMS 45. Between my sidemounts and stages I had 210 cu feet of gas configured in a very low profile rig. The temperature in the first sump was in the mid 40s and it felt great when I broke through the thermo cline 300 feet in and hit the 50 degree water. As I began my assent from a depth of 32 feet up the slope at this point the vis also opened up to a respectable 15 feet and I followed the line through some large sections of Florida like cave. At a penetration of 400 feet the passage narrowed down from its 20 + foot width into a high wide canyon. At a depth of 4 feet I passed beneath several small air pockets that marks the end of the first sump. At the end of this canyon the second sump begins as a large broad 40 foot wide room with a flat 3 to 4 foot high ceiling. I followed the line through its center till it intersected the right wall at a depth of 20 feet and then pumped some gas into my DUI pinning myself against the ceiling. Comfortably positioned I detached the Alum 30 from the 45 and placed it on the line. Continuing on the 45 stage I followed the line as it headed down to a depth of 56 feet and intersected the dome pit 720 feet in. This dome marks the end of the second sump. At the base of the dome is a restriction that requires you to dip down and arch your back as you pass through. I slipped past this point and finned into the bottom of the dome. To my left the line headed straight up and I added a shot of gas into my suit to begin my gradual assent floating horizontally facing it. At a depth of 40 feet the cave opened up on the left and I departed the line following this wall up a gradual slope performing short safety stops ever 10 feet. As I neared the surface I was following what appeared to be a giant half funnel, its surface smooth and light in color while the walls on either side were decorated with thousands of thin black fragile ledges that protruded 3 to 5 inches into the passage. Under dryer times I suspected that this slope might have been a waterfall. With my final stop completed at 10 feet I continued up the slope and crossed the smooth lip at a depth of 4 feet. Above be was a large air filled 20 foot diameter dome but with no reason to surface I headed back down to a depth of 10 feet following the line into the third sump. This section of cave truly reminded me of Florida with a height of over 15 feet and width of 10 + feet. It bottomed out at a depth of 13 feet before heading back to 8 feet. As I finned forward the line crossed a shear lip and plunged straight down into sump 4. I crossed over, vented gas and free fell next to the line to a depth of 27 feet where it headed of into a side passage. Passing through a wide restriction I followed the line into 15 by 6 foot high passage and back toward the surface reaching the end of sump 4 at a penetration of 1200 feet 23 minutes after leaving the entrance. Before me lay 150 feet of mostly walking passage, I removed my fins and leaving my stage on the shore crossed this dry cave enjoying the warmth that this exertion generated. My Rock boots were worth their weight in gold and made moving the 120 pounds of geared I was wearing a piece of cake. I was floating in the head pool of the 5 th sump 6 minutes later. I had not had to use any of my side mount gas up to this point so I was able to start out with full tanks for my push of the fifth sump. It started out as a 10 to 15 foot wide passage about 3 to 4 feet high gradually winding back and forth as it slowly dropped in depth. The vis in this sump was at least 20 feet so I had a good opportunity to examine the line and walls as I finned forward. Everything was as I had left it on my previous push and I soon reached a depth of 51 feet 300 feet in. At this point the cave gradually began to ascend. At a depth of 48 feet my large explorer reel and the end of the line came into sight. I picked up the reel, shook out the sediment and pushed forward into virgin territory. The passage continued much as it had before and after 20 feet I pulled a Disler Spike from beneath the bands on my right side mount and attempted to place it. It went in three inches and bottomed out. I gently pulled it out, drifted 5 feet to the right and to my relief found a deep section of sediment and got a good placement. I was expecting the reasonably thick sediment in the sump to continue and had not brought any drop weights with me, fortunately the cave cooperated. I wrapped the line twice around the slot near the top of the spike and pressed on continuing to place spikes at every bend. After a 150 feet the passage passed a depth of 30 feet and a dome appeared above me to my left. It was 10 feet in diameter and headed up at least 15 feet. I shone my HID into it but it appeared to be a dead end so I continued following the lower passage. As the line whirred off my reel and the passage passed through 20 feet I began to suspect I was reaching the end of the sump. I could hear my bubbles rushing along the ceiling as they headed upward. At a depth of 10 feet I was almost out of line when I saw the silvery reflection that indicated an air space gleaming back from above me. I continued on and slowly ascended to find my self in a large air filled canyon with a 6 foot high ceiling. I could see another 20 feet of air filled cave to my front where it appeared that it dipped below the water level once again. The passage was hour glass shaped and just below the water level at this narrow point a large natural tie off protruded from the right wall. It was the perfect size in the perfect spot. I swam toward it planning to do a tie off only to discover that I was three feet short so I had to settle for placing the reel in the sediment on the bottom. I had managed to degrade the vis quite bit by this point, and with another three hundred feet of new line laid I opted to turn my dive and head back out. Despite the disturbance my earlier passage and spike placement had caused I still enjoyed a good foot of vis on most of my return swim. I surfaced after several safety stops having used a 1/3 of my sidemount gas for this push. After emerging from the sump I dropped my gear and treated myself to a lunch of granola bars and Gatorade, it is amazing how much gear you can put in the large pockets on a DUI, I then surveyed the dry cave between the sumps four and five and spent some time gazing on the beautiful crystals that lie in some fossilized rim stone pools in one of the side passages. This kept me happily occupied for a 2 hour surface interval. My exit dives through the first four sumps proved uneventful but some what chilly. The most memorable part is always the decent down the dome pit marking the second sump. The free fall into the dome is one of my favorite parts of the return swim. As you enter the top of the dome and follow the line just below the surface the downward section of the line abruptly comes into view. At this point emulating a sky diver you dump some gas and begin your downward plunge as the ledges rush by arresting your decent just as you reach the restriction. In my absence the sun had burned off the ground fog and I surfaced to find a beautiful sunny day. I took advantage of this letting the suns rays warm my frigid body while Dave did a second familiarization dive up to the turn just before the deep part of the first sump. All in all another successful day for the team with the fifth sump cracked and the line pushed to a penetration of 1900 feet. Based on the existing survey we are now 10 % of the way as the crow flies to the downstream sumps in Buchanan. The goal of connecting to this dry cave continues to beckon to us. If it is doable it appears that it will not be easy. But then if it was there would be no reason to do it. We have now reached the point where establishing a small base camp between sump 4 and 5 appears to be warranted. It should also be possible for a support diver to transport an additional alum 30 stage to the beginning of the 5th sump. If we can pull this off I could start my push at the next sump with full sidemounts. Needless to say we can�t wait to go back to see what this incredible cave does next.
