by ·Comments Off on Perkins Cave Re-Survey Trip 4/8/2023

Back in the 1960s, Perkins Cave was surveyed using carbide lamps to mark stations and trying to extend the cave in many directions at once. The 1972 map shows blobby walls and no passage detail over in the U Survey section. Naturally there must be some leads going north that they missed. 


The blobby northern section is mostly a massive wall of breakdown. Our March trip tried to survey a way over or to the right of the massive breakdown pile. We met only dead ends too small for humans. On April 8, Emily Graham, Piotr Suder, and I headed to the lower section and to the left of the breakdown pile. We still hoped that the breakdown pile could be surveyed over/under/around/through.


The previous day’s deluge left the breakdown drain area wet and slippery. Piotr and Emily pursued the slippery lead into a hole that quickly became too tight for humans. Off to the left we scaled and surveyed our way up into a room of pickup truck-sized breakdown. Off in one corner we found a dead bat clinging to the ceiling and covered in white nose fungus.  Behind that Piotr squeezed past other fungus on the floor and into a breakdown-choked passage.

Alas, no good leads. Piotr did a great job leading us out of the cave without ever consulting the old map. And I fastened the lock on the cave gate in under thirty seconds.

At the February TriTrogs meeting, we had enough members interested in a survey trip. It’s great when a trip gets mostly planned at a meeting. Matthew Weiss, Maria Droujkova, Emily Graham, and I stayed at Tanya’s house in Marion before the trip Saturday morning. We had no trouble finding our way back to the Perkins Cave survey lead, but Matthew and Maria photo-documented the trail to be sure we’d get back.


The stooping lead in the U Survey section took Emily (and the rest of us) beneath a massive breakdown pile and then turned into a low crawlway. It opened into a pantry-sized room and then into another crawlway. That one ended in a larger room with no human-sized exits.


We spent time trying to find another route past the breakdown pile but had no luck. It was still better luck than Maria’s boot had had, so we exited the cave with less survey footage than I would have liked. Fortunately Matthew was eventually able to re-lock the cave gate when we exited.

It had been a few months since the last TriTrog sport caving trip, so I offered up the traditional Hancock Cave Bat Count trip for New Year’s Eve. I don’t think we had had a bat count since pre-Covid, and a warm chili dinner at Tanya McLaughlin’s house seemed like a good idea in the frigid winter temperatures.
But it wasn’t actually cold New Years weekend. The mountain road was fine despite the icy waterfalls that still decorated the mountainside. We discovered that the stream outside the cave entrance was still frozen that morning around 11 AM when we crossed.
Laura Young and Emily Graham rigged a handline at the entrance. Laura’s exuberance during the trip was outweighed only by her cave pack. We were treated to bats in the Entrance Room and several other locations. Emily seemed best at spotting all six bats we found, and Laura’s experience with the Virginia Natural Heritage Program helped us identify the likely species from a distance. Emily’s Zebra Light made that possible. Laura appreciated that I hold out hope that some year we’ll find many more bats wintering in Hancock Cave. But not yet.
We took a side trip up into the Vertical Maze because Emily hadn’t explored that part of the cave before, but nothing up there looked very familiar to me. We traversed the passage where Tanya had led her first survey trip, but I think we needed to descend about twenty feet just to be near the top of the Breakdown Staircase.
As we spent five hours exploring the cave, the icy waterfalls and streams outside had thawed in the rain, so the Entrance Room greeted us with heavy waterfalls and a very slick trip up the handline and out of the cave. I found myself rolling from side to side to make any progress as I reached up for the handline used to haul out the cave packs. Near the top I tried again rolling my legs from side to side to fit out the entrance from my crouched position, with my knees catching on the ceiling by just an inch.
A great trip overall, but the new trail to the cave entrance is still mighty slick during a winter thaw.

Emily Graham and I accepted Vardell Smyth’s invitation to use his home in Boone, North Carolina as a launching point for a survey trip into Perkins Cave (Washington County, Virginia). Jason Lachniet trusted me to find my way back to the leads I left beyond the Second Discovery area of the cave.


Emily had to correct the routes I tried three times on the way in, but Emily, Vardell, and I made good progress toward the survey lead for the day. Our second survey station brought us up into the Gypsum Pancake Room, three-to-four-foot high and roughly thirty feet across. Side passages of varying sizes abound along this passage. The floor is composed of crumbling thin slabs of ceiling, but typical stalagmites and soda straws populate the indeterminate walls.


Surveying crawling and walking passages around the perimeter led to some dead ends and to one huge room (yet to be surveyed). Our original one lead left us with 468 feet of survey and roughly five new leads that all appear somewhat substantial. When finishing the last survey station, Emily was welcomed by nocturnal cave residents in what we’re calling Nibblers Way. Field mice gathered round her while I finished the sketching and even seemed to follow Emily as we exited the cave. With the mice to guide her, we exited with no wrong turns.

I’ve cleaned up lots of cave graffiti on conservation trips in the past, but the VAR Spring Restoration was my first foray into cleaning lampenflora from the cave walls. Slightly paraphrased (by Meredith Hall Weberg from Hildreth-Werker, Val, and Werker, Jim ed. Cave Conservation and Restoration, C 2006, pp.343-344):

“… Lampenflora is a collection of photosynthetic organisms (blue-green algae or cyanobacteria, algae, mosses, and other plants) that grow near artificial lights in the cool, humid cave environment.  Lampenflora are not ‘natural’ or “native”; they are brought into the cave on visitor’s shoes and clothing.  Lampenflora found along cave tour trails are considered opportunistic in cave ecosystems.”

Twenty-four VAR cavers, including six from the TriTrogs, came out to Endless Caverns to help fight off the lampenflora that hadn’t had serious attention in ten years. It turned out that the staff had likely been doing spot cleanings, but I noticed green formations as I left the Oriental Palace. I was assigned a resupply role and a heavy water sprayer; Dave Socky and I followed the scrubbers into the cave.

Scrubbers were cleaning the Mitten Room, Vista, Hindu Temple, Sky Land, and Grand Canyon as we walked along, but they didn’t need our help. The ceiling got high when we reached the Marine Corridor, so Dave and I tried to devise ways to reach the ceiling lampenflora twelve feet off the floor (with limited success). Emily Graham chose lamps closer to the floor and spent the next hour there with Dave de-greening the walls and formations.

I followed Stephan Francke and Taylor Orr into the Oriental Palace and helped them spot green patches on the formations. They pulled out their toothbrushes and began spraying with hydrogen peroxide. I headed back to the entrance for more supplies and encountered Chris Flannagan and his son on their mission to replace burnt-out light bulbs. We encountered many scrubbers who thought that they were heading out of the cave for lunch, but they were actually headed back in.

After VAR sponsored a free lunch, we expected that everyone would be cleaning graffiti beyond the front maze. Dave and I spotted some lampenflora for a group with weaker headlamps. I noticed it’s even easier to spot the green fuzzies from other people’s lamps. In Alexandra’s Ball Room, we found more high lampenflora, so I started to exit the cave in search of a ladder. After a few turnarounds initiated by the people we encountered, I found myself heading into the cave in search of a ladder stored in a side passage.

I never found that ladder. Chris and his son helped Tommy Carpenter and I look, and we passed Emily and Stephan scrubbing in a lower passage. Eventually we reached the back of the tourist trail and helped the Flannagans replace old light bulbs. I’m afraid we missed the turnoff to Fairyland.

Emily, Dave, Tommy, and I exited the cave very slowly, stopping to scrub many times. Emily spent a good amount of time converting the Snow Drift from green to white while we whitened up the formations in the adjoining hallway. Boulder Canyon had a single lamp at the top lighting lampenflora on the walls, ceiling, and floor. When we completed scrubbing there, we headed out (after sharing the Cathedral’s beauty with Emily).

Wonderful veggie pizza dinner from VAR that evening (with the cave manager) and a beautiful night for camping.

In attendance: Ken W., Emily G., Zeke VF, Martin G., Mike B., Ann O’N., Arthur, Louis L, Hannah S. and Luke, Stephan F., Ellen S., Joe J. Michael E., Pete H., Taylor T., and April N.

Arthur asked about sharing some photos from a possible cave and agreed to set up a time to meet at a coffeehouse to share.

Mike Broome shared a draft of the Treasurers Annual Report and answered questions about the computations. In 2021 the grotto paid $95 for web hosting services and $200 for the donation to West Virginia Cave Conservancy. Mike will post the Treasurers Annual Report.

Stephan claimed his pullover that was left at Ken’s on December 5, making his meeting attendance fully worthwhile.

The upcoming trips list was very abbreviated and only included the April 19 VAR conservation trip and the May 20-22 MAR/VAR regional events. Members were encouraged to add their upcoming trips to the TriTrogs Google calendar.

Pete H. agreed to share a PowerPoint presentation about his trip to Mexico at an upcoming meeting.

Pete described his trips to vertical caves in Alabama. He stayed in the lap of luxury at a lake house. His trip began at Balcony Sinks Cave with a 200-300 foot drop. At the base of the pit, the group climbed a fixed rope into a cave passage that eventually dropped into a stream. This led upstream into a sixty-foot wide room filled with flowstone.

Pete’s second day of caving took him to Natural Well Cave in a residential community with a small 15-foot-by-15-foot entrance and no water running in. He rappelled onto a bunch of fallen trees and travelled downslope from there. It led to a small crawling passage that eventually opened to a tall room (over 150 feet high) with a small waterfall. Pete offered a safety note about the trip out.

Pete’s final caving day led him to Stephen’s Gap Cave, a cave with a key-coded parking area. As Pete’s team hiked to enter the cave, they passed a stream plunging into a cave entrance. A little old lady could walk into the second entrance, but Pete’s team took the time to rig and rappel into the entrance down through the heavy spray of a waterfall. Through a series of rope pulldowns, the team descended into a fast-moving stream passage and soaked the cavers. They exited through the first cave entrance.

Zeke then led the TriTrog officer nomination process, and only a single person was nominated for each position. The entire slate was accepted by acclimation, and the other members offered congratulations to the new TriTrog officers:

Chair: Zeke Van Fossen

Vice Chair: Louis Le

Webmaster: Taylor Tibbs

Treasurer: Mike Broome

Secretary: Emily Graham

Zeke mentioned his plans to deliver a program about scenarios in the future.

Discussion turned to the cat formation in southwest Virginia before the meeting closed.

In virtual attendance: Carlin Kartchner, Taylor Tibbs, Stephan Francke, Louis Le, April Nieuwkoop, Mark Daughtridge, Mike Broome, Diana Gietl, Pete Hertl, Lisa Lorenzin, Zeke Van Fossen, Jackson Lemons, Ken Walsh, Martin Groenwegen, Zafir, and Emily Graham

Peter parked at the fairgrounds to witness the eclipse.

When introducing themselves, attendees were asked to name underground cave-adapted creatures they had seen (in real life or on television [no sci fi/fantasy]). The list included crawfish, a translucent salamander in Rehoboth Church Cave, fish in a pool losing pigment, insects with long antenna, bats, swifts, blind fish, Florida cave life (fish and salamanders), jumping teens, troglophile, albino exauto, grotto sculpins, and crayfish too small to eat.

Peter discussed his upcoming trip to Golondrinas Cave in Mexico.

Officers conducted a Zoom poll, and the meeting attendees chose to donate to West Virginia Cave Conservancy again this year as a charity.

The grotto currently has four helmets and lights for loan to members. Mike will take recommendations from members about what replacements should be bought and will later focus on possible purchases for the grotto. Discussion of lamps commenced. The Black Diamond brand lamps (Icon) did not last long because the casings broke too easily. Let Diana know if you have recommendations for camping lanterns inside a tent. 

The recommendations included a discussion about eneloop rechargeable batteries that do not corrode.

We discussed the NCRC callout list, and Ken forwarded the email to the grotto members.

No one had trip reports to share, and the next upcoming trip announced will be the Spring Restoration field camp on April 23. Hopefully members will enjoy some caving camaraderie before then.

Zeke Van Fossenn shared a fascinating program entitled Troglomorphy and Cave Fishes. It sparked many questions and references to old musical bands (Dire Straits and Styx).

Zoom participants included Jess Keeley, Taylor T. (Vice Chair), Stephan Francke, Michael Ehmke, Louis Le, April Nieuwkoop, Mark D., Mike B. (Treasurer), Diana G., Alec Payne, Peter H., Zeke vF (Chair), Lisa L., Jack Anderson, Ken Walsh (Secretary), and Susan Hudson.

During the introductions, we spoke about what we did and didn’t know about bats. One person wanted to know how many species had not yet been discovered and another how many cave species we know that are in NC. Diana described her boot-deep experience with the guano in Devils Sinkhole Cave in Texas where the mound is stories high. Bats and humans both use echolocation. In flight (not diving), a bat species (freetail?) is faster than any modern bird. 

When visiting a cave with vampire bats, use lime juice beneath your nose to block out the blood curdling smell. Pete is an ideal person to study bat guano. Oilbirds in Venezuela may be one of the best species for spreading tree seeds in the rainforests.

Discussion turned to replacing some of the grotto’s loaner gear. Three quarters of the lamps work but have small cracks. No one has priced out new gear yet, and we expect that any new LED lamps may be better than the ones in our current collection. A suggestion was made to possibly include small cave packs in the grotto supplies.

The TriTrogs have also donated to charities in the past (Bat Conservational International and Southeastern Cave Conservancy were the last two). Officers are soliciting suggestions from members about which groups deserve our donation this year. We are not restricted from donating to the same sources as in the past.

Discussion turned to the NSS charter of the Vertical Training Commission. The idea wouldn’t be to certify cavers as vertically competent but set up guidelines that would be followed by the trainers. The idea is to avoid vertical training schools like the one in France and would be divided into different skill levels: basic rope techniques, rigging, advanced techniques, expedition-style caving, and self rescue. Inexperienced cavers have recently been having more vertical issues and involved in accidents, and the feedback points to them being undertrained to handle underground situations.

Reams and reams of training materials already exist, and multiple groups are already offering weeklong classes (that amount of information can almost overload some students). The NSS charter is set up to choose the team that will train the trainers, and one TriTrog member advocated that the best place to train is locally. The charter talks about finding people who are adequately qualified to train the trainers in different regions around the country but does not address how they will secure these trainers without compensation. An online town hall for NSS members was set for October 28.

Ken shared the results from the 173-foot survey course from the September meeting; he compared the teams that finished the course. Emily and Stefan were the fastest, Zeke and Taylor came in second for their horizontal closure (2.5 feet), Alec and Mark managed second place for their vertical closure (2.5 feet), and Louis and Carlin were the slowest (but managed a vertical closure of 0.5 feet and a horizontal closure of 1.4 feet).

Mark D., Jessica, Jack, Laurel, and Carlin went to Worley’s Cave in Tennessee for a sport trip, along with two children. The kids had a great time in this easy walking passage. Formation colors weren’t astounding but were massive, covering large walls and mostly free of graffiti. The stream water on the return trip was mostly shallow, and they saw a great horned owl perched inside near the entrance. 

Pete Hertl described a drop down Grapevine Pit into Lost World Caverns and another trip into Buckeye Creek Cave. In an area with significant breakdown, they hope to find a human-sized exit from Buckeye Creek someday directly onto Todd Handley’s land.

Zeke knew nothing about upcoming trips.

Because members had backed out on sharing programs, Taylor shared a portion of a YouTube video entitled Virginia’s Beautiful Bats (https://www.youtube.com/watch?app=desktop&v=eAeLY7TV0TI) by Leslie Sturges. Starting the video around the 12:30 mark, we learned a lot about the bat species in Virginia (of which many are found in NC as well). Sturges’s slides used gummy bears to represent the bat species weights and Twizzlers to represent the wing spans.

by ·Comments Off on TriTrogs General Meeting Minutes from September 28, 2021

Zeke began the meeting with a “Hear ye, hear ye!” For introductions he asked members to share their names (April, Louis, Mark, Mike, Taylor, Emily, Ken, Stephan, Alec, and Carlin) and who they’d like to join them caving. Answers ranged from family to fiction.

Stephan shared a trip report about his travel to the lava tube Ape Cave in Washington. He described that visitors now must reserve a two-hour time slot for the visit and that he didn’t have time to see all of the 1.2 miles of tube.

In the business section of the meeting, Ken called for suggestions about a grotto donation this year. Mark D. suggested that the grotto consider replacing some of the aging loaner headlamps.

In terms of upcoming trips, Carlin Kartchner is planning a horizontal sport trip Worley’s Cave in Tennessee (Oct. 16) and a survey trip into a small lead in Cold Sink Cave. Ken mentioned the Grand Caverns Restoration Camp in April. Mike Broome hopes to plan a vertical practice, perhaps at New River Gorge.

Ken then paired up experienced and less experienced cave surveyors (Alec and Mark, Louis and Carlin, Stefan and Emily, Zeke and Taylor, and Mike and April) to learn survey techniques. Four of the five pairs completed a circuit of four survey stations over 173 feet. Their horizontal closures (in ascending order) were 1.4, 2.5, 4.5, and 4.8 feet. Their vertical closures (in ascending order) were 0.5, 2.5, 2.8, and 3.7 feet. We’ll announce the team with the best closure at the October meeting.

In attendance: Arthur, Louis Le, Mike B., Zeke VF, Michael, Ann O’Neil, April N., Lee Olson, Taylor T., Emily G., Pete H., Carlin K., Andrew Kowalenko, Lisa L., AK, Ken W., Stephan, Ava Pope, Ben Burton, Skylar Hopkins, and Elise S. in attendance.

Zeke asked everyone to introduce themselves and then share why people go underground and their favorite fungus. The list below covers only the former:

  • to see the edge of the known
  • to escape being yelled at for getting muddy
  • to have fun
  • to explore
  • to have an adventure
  • to enjoy the fellowship
  • to keep doing what she did growing up
  • to see an upside down world
  • to feel connected to other times
  • to learn and be scared
  • to escape allergens
  • to hear perfect quiet
  • to feel awesome and satisfied
  • to feel the joy of discovery

Taylor discussed the survey responses regarding the grotto member comfort levels about meeting in person. Grotto members are comfortable meeting in person but would rather be outdoors. Some members said that they’d be willing to check vaccination status of members when we get together. A breakout room was set up after the meeting to discuss how hybrid meeting options might work. Ensuring some consistency in online options will be a goal, and hose interested should contact Taylor at vicechair@tritrogs.org.

Mark D. described a beginner’s trip to Hancock Cave with Michaela, Jan, and Tine. He reported that a massive rain storm took out the trail markers outside.

Louis Le described his trip to Crozet Tunnel in Virginia.

Mike and Lisa described a trip to the historic section of Butler Cave. They first enjoyed the Perseid meteor shower and finished the trip by discovering that the gate on the historic entrance cannot be unlocked.

The only upcoming trip listed was the VAR/MAR event in October.

Mark Daughtridge led an online lecture titled “What the Heck’s a Fungus Anyway?” and largely spared the puns.
