NEST TRIP REPORT Buchanan Cave 21 July 2001 The Northeast Sump Exploration Team, NEST, conducted exploration efforts In Buchanan Cave Resurgence in Virginia on 21 July 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. Jeff and I returned to Buchanan to continue with our survey efforts. For this dive we were both using buoyancy compensated 80 stages to pass the first four sumps. Despite fairly dry weather, conditions were far from ideal with only about 5 feet of vis. Jeff was being to wonder if my descriptions of 20 to 30 feet of vis was a bad joke since all of his dives at the site thus far had corresponded with poor visibility. Based on the conditions Jeff opted not to dive the 5 th sump so I pressed on with my backup plan to finish the survey of this section of the cave. With my 10 watt AUL HID hanging over my left shoulder providing illumination I picked up where I had left off a few weeks ago surveying from a depth of 25 feet up the sloping passage to the surface. I was pleasantly surprised to discover that the vis in sump 5 was a decent 10 feet. After surfacing I continued the survey to the end point of the line on a mud bank on the left through about 120 feet of air filled passage. Beyond the point where you leave the over head environment behind is a wide passage with a high ceiling with 6 inches to three feet of water covering the floor. The easiest way to traverse this is to float and crawl. After 200 feet you reach dry land, a mud bank where I dropped my sidemounts. I planted a Disler Spike in this bank and used this to secure the end of a tape reel and surveyed from this point back to the line tie off point. I was now wading through the shallow passage stirring up a vast amount of silt that was flowing downstream into the sump. There was no way to avoid this and by conducting this part of the survey solo I would not subject another team member to the challenging visibility conditions I was generating for my outbound dive. With this part of the survey completed I headed up stream to enjoy Montgomery Falls and give the heavier silt time to settle. This water fall or cascade is over 100 feet long and 20 feet high and is one of the most surprising and beautiful features of the cave. For my exploration efforts today I was wearing a DUI CF 200 front entry dry suit. This is the standard configuration for NEST and has excellent abrasion resistance, a must considering the abuse we subject our suits to. The dry suit was equipped with two large Velcro closed bellows pockets on either side, military length Kevlar knee pads and elbow pads, zipper guard and warm neck collar. I was also wearing a pair of Halcyon Gaiters and a pair of hard plastic knee pads with Velcro attachments. The Velcro holds the pads reasonable secure but also allows them to be striped off if they become wedged passing a restriction. My gloves were contoured ice fishing gloves from Wallmart with the fingers cut off and the over board dump valve was a stainless steel urinator from Dive Rite. The suit was also equipped with rock boots. I have seen a number of less than positive remarks regarding rock boots on various lists. For our environment they are an absolute must since at most of our dry suit sites we are traversing dry cave wearing over 120 pounds of gear. There is no comparison between the rock boots and standard dry suit boots in this application. Standard dry suit boots are like wearing a kids pajamas with attached feet that flop all over the place. I can make this comparison since I have used both standard wet suit boots and rock boots in the same cave, the performance advantages I experienced first hand leave no doubt in my mind regarding this. I now use them for all of my dry suit diving including some limited wreck and recreational diving and love them. Having made this statement it also important to realize that using rock boots takes some getting used to as well as proper technique. Proper sizing is vital in that the sock material should be large enough to accept the foot and insulation but not too large so that the excess becomes uncomfortable by being bunched up in the boot.. I wear a pair of wool socks and thinsulate lined Seal Skinz socks over these for insulation. When donning the boot you need to develop a technique to seat the excess fabric correctly, not hard but it takes some practice. It is also vital that the boot laces be snug but not overly tightened. The proper fin size is also vital, I am fortunate in that my size 10 Rock Boots fit perfectly in my extra large Jet fins with spring straps. Although it took me about four dives to refine my technique to make effective use of my rock boots it was well worth the effort. After a look at the falls I headed back and donned my gear for the exit swim. I was encouraged to discover that most of silt I had stirred up during my survey had not fully migrated into the 5 th sump and I could actually see the line, from about 4 inches that is. I rejoined Jeff and after unpacking supplies, stocking the first base camp, and reballasting our stages we exited. Another excellent day for the team with the 5th sump survey completed and more supplies positioned for a future push. 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.
