Lava Beds

At the last grotto meeting, I shared photos from my trip to Lava Beds National Monument and tried to discuss some of the geology. Needless to say, that doesn’t translate out as a trip report. Therefore, I thought I’d add a trip log here. I won’t bother with the names of the California caves because I don’t need Buford Pruitt summarizing this trip report in the NSS News. Interested parties should refer to the Cave Research Foundation (CRF) pages for official trip reports (cave-research.org), but I don't think you can do that online.

September 21 – Due to a prior commitment, I arrived at the fieldhouse three days after everyone else. Because they sent ME on a wild goose chase looking for cheese sticks in the wrong grocery, I arrived after dark but still found dinner waiting.  They liked my DSLR camera when I pulled it out to take a scorpion photo.

September 22 – My pretty camera got me nominated to join the team exploring a lava tube cave in Modoc National Forest that passed back under Lava Beds NM. In addition to the camera gear, I had to take along vertical gear for a 25-foot entrance drop. The rope landed atop a 150-foot high breakdown mountain with a 40-foot wide passage. While two party members explored down a narrow vertical lead, I traveled with Paul McMullen and Mark Jones along the main passage and collected some photo documentation of the cave. Pretty cool to be the first person to photograph this enormous lava tube and only be the eighth person to ever see it.

September 23 – A geology field trip taught me a lot about basalt, obsidian, pumice, andesite, a’a, and pahoehoe across the Medicine Lake shield-like caldera.

September 24 – One of the longest caves in the national monument still required a bit of mop up work to complete the map. At the first spot, Ed Klausner completed a complicated vertical sketch, and then we descended. I didn’t see any of the ice I heard about on the lower levels. I then supported the four pieces of a hunting stand while Ed climbed a lava fall only to find a dead end. The smaller folks then squirmed into a tight lead at the bottom of the cave while Paul and I looked for other leads and removed old survey marks. Dave Riggs, the park technician along with us that day, told us that the white crust on the walls in this windy cave was actually calcite.

September 25 – Mark Jones and I conducted some mop up survey in the Balcony flow. We were much too big for this passage, especially with me on lead tape. We were able to make visual connections to the surface and even see Paradise, but we were much too large to get to Paradise from our purgatory. We ended up abandoning one survey station near a cave entrance because the iron in the rocks was consistently throwing the compass off by FIFTY degrees.

September 26 – Back to a different cave in the same flow with Dave West and Karen Willmes. While surveying, I dragged my body over the loose volcanic cobble until the room where we looked up to a skylight twelve feet above my head. I prayed for a miraculous rope to drop from the hole, but ultimately we had to return through the cobbly area “where angels fear to tread.” When we put the surveys together, it was easy to locate the nondescript skylight (I’m not sure I’d fit wearing vertical gear) from the surface with compass and tape.

September 27 – As we began our journey back to Reno for the flight home, we took the scenic route through Lassen Volcanic National Park to check out the geothermal features (steam geysers and mud pots).

Pleasant Surprises

By Emily Graham, Joel Johnson, and Ken Walsh

The gate was locked. The landowner was not home, so we needed an alternate plan. I (Ken) was not too displeased with the forced change because my previous encounter with Rail Valley Cave was not enjoyable (see January 2015 trip report).  Joel Johnson, Emily Graham, and I ended up surveying Beaver Creek Cave on Saturday and saved Rail Valley Cave for Sunday, and that turned out to be the best possible solution.

Each of us had several pleasant surprises that we’d like to share as our trip report (attributions below do not reflect comments by one of us specifically because they were composed during the drive home).

Emily’s Pleasant Surprises:

• Learning how to survey afforded her time to hear the croaking sounds from the formations.
• She hadn’t been missing any great clothing buys when Joel’s knee-high waterproof sealskin socks turned out to be 100% water absorbent.
• The rimstone dams were quite pretty in the section of cave where she was looking for a light connection with Ken, even if she had missed the turn in the passage.
• The stream outside Beaver Creek Cave was a wonderful place to wash gear, and the intermittent pools in Rail Valley Cave were great for cleaning the tape measure.
• The distance between survey points in Rail Valley Cave progressed from an average of 7 feet in the first two shots to an average of 42 feet in the last two shots.
• The trains running overhead didn’t cause Rail Valley Cave to collapse.
• Baby salamanders swam in rimstone pools with colorful banding (the pools had colorful banding, not the salamanders).

 Joel’s Pleasant Surprises:

• Inner Mountain Outfitters sent his virgin cave suit and Swaygo pack by next day air in time for the trip.
• Though he couldn’t fit down the first lead where we began survey in Beaver Creek Cave, we found an alternate way to the bottom of the slide.
• Ken’s loaner wet suit was appreciated when he splashed down the slide into the stream.
• Swirling black reflections on the water’s surface were mesmerizing.
• Free ice.
• Bonnie hugged Joel for saving a crow stuck in a tree.
• Wet caving clothes dried to a damp level after being left out overnight, retaining enough moisture to slide on easily and keep us cool on Sunday’s hike through the jungle.
• It wasn’t a human skull; it was only a milk carton.

 Ken’s Pleasant Surprises:

• Emily had a seemingly endless supply of rocks that Ken could bang against the ceiling until the passage was large enough for him.
• When he was forced into doing splits crossing Sculpin Lake, the water remained below the waistline afforded by his neoprene pants.
• Joel was willing to drive his truck through the jungle to Rail Valley Cave.
• The entrance to Rail Valley Cave was dry (a disappointment to Emily until after she crawled inside).
• Two novice surveyors surveyed so fast that Ken had to make them stop so the sketching could catch up. Ken also didn’t have to erase any numbers on the Sunday survey.
• Ken remembered that his cell phone was lost along with his keys, wallet, and pants.
• Emily and Joel (wearing Ken’s wet suit) had been talking about how stream water was warming their feet in their wellies rather than about the other fluids mentioned in their previous day’s discussion.

 And, for the numerically inclined, we surveyed well over four hundred feet of cave. Joel and Emily might add more comments below.

FOAMHENGE! (and Spring VAR)

Our group of TriTrogs (Ken, Diana, Emily, and Rob) rolled into Natural Bridge, VA, on Friday night to find a cold, busy campground brimming with cavers. There were well over 300 registered for Spring VAR, hosted this year by the BATS. After verifying that Saturday's guided trips were full, we found Tanya and, eventually, our campsite. Many thanks to Lee for his intrepid campsite wrangling.

Ken got the dirt on a pair of nearby caves, namely Brady's and Brady's Hidden. The proximity allowed us the luxury of sleeping in on Saturday while those bound for farther reaches geared up in the cold early morning rain. After breakfast and canopy assembly the four of us were joined by cabin-dwellers Wendell and Joel.

What we saw of Brady's can be summed up as about two hundred feet of stagnant, foul-smelling cave that showed heavy signs of raccoon use. Two tri-colored bats were spotted. One obliged Rob by submitting to numerous tests of his various macro camera settings. We exited to a light, brief rain and sought out Brady's Hidden Cave. Rob found it a couple of sinkholes away, below a large triangle of exposed limestone that may as well have been a blinking neon sign. We navigated about a quarter mile of cave, which included a tiny spring, a small, pretty room filled with active formations, short, interesting climbs through large breakdown, and the welcome discovery of an alternative route that prevented my rib cage from suffering the same indignity twice.

That evening we gathered at the Natural Bridge Hotel for dinner, followed by Ernst Kastning's presentation on the history of Natural Bridge, followed by door prizes. A local band entertained the campground until 11pm. Sunday morning Front Royal Grotto offered an affordable pancake breakfast.

Ken attended the VAR business meeting. The new VAR website (var.caves.org) has a closed cave list that they are trying to keep current. Archived issues of the Region Record are also online, and hopes remain for an index to same. Various conservation projects were mentioned. Fundraising continues for New River Cave. And Walker Mountain Grotto became an official member of VAR and agreed to host Fall VAR this year! At least that's what we all heard.

Before leaving town we visited Foamhenge, a life-size Styrofoam model of Stonehenge. Only better, because it has most of a life-size model of Merlin the wizard presiding over it. It was totally worth the price of admission.

Grand Caverns Easter Restoration Camp 2015

Even though other TriTrogs all backed out, I elected to reroute myself a bit for this year’s Grand Caverns Easter Restoration Camp. I drove up Friday evening in time to catch dinner in Grottoes, Virginia. This solo effort left plenty of time to socialize with the other two dozen cavers before work began on Saturday.

I spent the morning hauling buckets of gravel through Grand Caverns’ majestic hallways while others painted doors and handled outdoor chores. We worked up sweats that were obvious to the tour groups we tried not to disturb. Before lunch the tour groups tended to be pretty small, but they grew to sizes over thirty in the afternoon.

After our free lunch provided by VAR, I shared a quick tour of the cave formations to some new volunteers. Then we returned to bucket hauling for a short while. I eventually peeled off to help spray clean algae growing on the formations; I was taller than the rest of the spray crew and could reach the high places that needed scrubbing. Some of the algae seemed so old that it’s below the flowstone surfaces now.

A few hours after the free dinner, I left to visit my family in Baltimore for a breakfast heavy on the Polish sausage. If you’re sorry that you missed this conservation effort, we’ll likely have more opportunities closer next winter as the VAR continues with on- and off-trail cave restoration efforts in Caverns of Natural Bridge next winter.

Hancock Cave with Walker Mountain Grotto

On March 8, Ken Walsh led a group through Hancock Cave. Four members of Walker Mountain Grotto were introduced to the cave during a thorough bat count. We tallied six bats on this trip. That's three fewer than were recorded last March, but five more than we spotted there in the fall. Bill Grose has posted a trip report with photos on Walker Mountain Grotto's website:

I tagged along and got the opportunity to revisit the graffiti cleanup sites that we worked on in November. Our efforts weren't wasted. The Grantham Room looks remarkably better. Our man-made mud still masks the writing on the sloping walls there. The more vertical areas that we had abraded with wire brushes look a little raw by comparison, but the overall result is gratifying. I didn't see any signs of new vandalism, unless you count the pack rat rubbish. A lot remains to be done. If you took part in the bat count last fall and you have any interest in a future cleanup trip, you'll be delighted to know that hauling giant buckets of water into the cave is entirely unnecessary; that was just for fun.

Over the River and Up the Cliff

The last day of February greeted us with warm temperatures and good road conditions. The snow had even been plowed from the Rich Valley road nearest the cave entrance, all piled up nicely along the edge of the road. Unfortunately the driveway down to the abandoned house wasn’t plowed. Eventually Dave and Rob found a way to get their vehicles off the road, and we headed straight up a snowy hillside. Best snow I had seen all year.

Ken squeezing into Beaver Creek

The entrance to Beaver Creek Cave was just the right size for me to squeeze in sideways, but I was less enamored by the snow melting into mud as I lay on my side. Dawson, Dave, and I formed the first survey team, and Matthew and Rob joined Carlin on a second. Dawson picked up instrument reading skills after just a few shots.

From the first real room, our survey led us into a bellycrawl (of course) that opened up into crawlway with nice formations. I was able to squeeze past the formations and continue all the way to a tight dead end at the back. As I waited for Dave and Dawson, I noticed that I was in a much colder room.

After regrouping, we headed into the big room that Carlin spent a good part of the day sketching. We set a station that Rob quickly coopted, so we just started our survey a little further down. We surveyed nicely decorated walking passage this time but had to step past the pits to a lower level. Around a bend Dawson found the Circus Bear Pit down a small hole in the wall.

Dawson tried to explore the pit, but his dad claimed dibs. As I belayed Dave down Circus Bear Pit, I noticed that this room also felt quite chilly. Apparently every lead I was finding led us closer to the snowy hillside. After completing our survey, Dave and Dawson learned how to use their camera while I poked down to the lower level. It should be fun to survey the interlocking passages down there.

More Rob, more Boxwork

Dave and I also looked up the passage where the other team would survey and heard serious running water. The other team told us that it led to a major pool of water that may have been twelve feet deep.

On Sunday we took a sport trip to Cave Ridge with Tanya McLaughlin. I went first into Boxwork Crystal Cave and showed everyone why the cave is misnamed. Cameras were pulled out, so we spent some time there. While everyone was exiting, I ran over to Radon Cave just far enough to find out that it still seems to be quite open and had not silted shut.

We then spent the rest of the time in Dead Air Cave. The horizontal entrance treated us to a good number of ice formations as far as twenty feet inside. However, I think everyone liked the big room with the spectacular formations, natural light from the pit entrance, salamander efts, and tiny crystals. Carlin and Dave promised they'd post photos to go along with this trip report, so be sure to check out the blog site directly.

New Years 2015: Another Perspective

Here's my $0.02 addition to Ken's trip report.

Rail Valley continues, but the real exciting potential comes after we complete the resurvey of the front of the cave. That hill has rather nice looking potential. I can promise some nice survey next trip, but the first two shots will be wet. Wet suits may be warranted. It's going to be a fun cave and has potential to be a rather long cave! It was fair of Ken to call the trip, but I was still pretty bummed about the early exit.

Saturday I was in the same cave as Ken, but party of a totally different group. I was privileged to survey with Brian and Stephanie who are always hilarious and fun to cave with. They continue to be a great help in surveying the occasionally awful but frequently rewarding Smyth county cave passage.

Our trip involved 3 different rope drops in different parts of the cave. The first was a nuisance drop of about 15’. After our survey of this area we left one lead with the sound of flowing water, but a rock hammer will be required to continue.

The second survey area already had three unsurveyed stations set from the last trip which really helped get things started. We started down this passage then eventually handed the horizontal leads to the other team so we could drop the pit. It measured ~40’ deep. There is large passage on one side of the drop which will require a bolt climb to access. Brian tried to free climb into it without success. He was on belay, but at one point fell about 5' directly onto Stephanie. Not one to give up, he kept trying until a large formation he'd slung easily broke off when he tried to weight it. Not good.

There is also a second stream that flows into this pit that also needs to be connected to surveyed cave.

Finally, the third area was a ~25’ rope drop. It took us a long time to figure out how we were going to rig. The top of the drop is narrow which initially made us nervous about getting suck on the climb, we exited without much effort. We surveyed a few stations to the bottom of the drop but will need to survey the room. There are a couple of bolt climbing leads here, and a going downstream lead. It was here that we found the best part of my weekend. A bunch of small clean rimstone pools filled with salamander larvae. There must have been at least 30 salamanders. So beautiful!

None of the remaining leads in this cave appear easy, but there is still a bunch of cave left to explore.

Rough current survey totals for SnoCone Cave:

Lenth: 3300’

Depth: 250’

Neither team got a ton of footage this weekend but we did add some good depth.

Than Sunday rolled around.

Dave and I wanted to continue caving. Everyone else either had to leave, or was still tired after what we'd done the last couple of days. We opted to start a new cave survey. With our main projects of the last year running out of easy work, we need to keep the survey queue filled. I’d prefer to avoid the shock we had after the Cold Sink survey finished at the same time as our other projects.

So, off to Beaver Creek Cave.

Not a lot to say yet. The survey Sunday was just Dave and myself, and we only had a few hours so it was a brief trip. Of everything we have going on, it’s probably the easiest to access, and the easiest to survey. The entrance is small, but I expect Ken will fit, and I also imagine Tanya will enjoy working this cave.
