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.
