[trip] Shovel Eater UpDog Survey

This past weekend was my return to Germany Valley after a 6 month hiatus; while our lead quickly died and we surveyed just under 90 feet, I was treated to a relaxing tour of several "new" parts of Shovel Eater Cave. Brian Masney and I drove from Morgantown on Saturday morning and met up with John Harman at his house, then grabbed a late breakfast - or rather, early lunch - at The Gateway. We stopped by the landowners' farm for permission to head in to Shovel Eater as well as to do some "landowner relations"; Brian presented them with a stack of glossy cave porn: some fantastic SEC photos that really impressed the family, the first that they'd seen of their cave.

After a lazy start, we managed to get underground at somewhere around 12:45. The trip in was uneventful; we stopped to snap a few photos for Brian and then dropped down the Ohio Bypass, which had only a trickle of water. At the HHA junction, we turned right and continued up the main passage until we ducked under a relict-flowstone shelf and rappelled a small pit with crumbly mud walls and some water raining down from the ceiling. From this point, the passages became a series of sinuous, tall, narrow canyon, where we continued to travel upstream and climbed up several of John Harman's bolt climbs to higher and higher levels, reaching the EFN survey, which had stopped at a 20 foot pit in the floor and a bolt traverse around the perimeter...

We finally began to survey, and as Brian snapped open a cyalume stick to use as a station light, it exploded, spraying his face and eyes with glow-in-the-dark chemical goo. Thankfully, he was able to stay calm and collected while standing blind, eyes burning at the top of a 20 foot pit; I did my best to flush his eyes out with an entire liter of water, and being the trooper that he is, he was then ready to shoot instruments. It was then that we noticed that this area of the cave has a jaw-dropping assortment of updog on the floors, walls, and ceiling, and it was obvious to us that this should be called the UDS, or "UpDog" Survey. Never before have I seen so much updog in one place!

Our survey shot across and over the pit, to a mud-and-breakdown slope which fed into a doubled-back canyon passage beyond. John had previously placed several bolts, and he rigged a traverse line to safely cross. The passage headed up to a wider canyon spot at mid-level, and up another 15 feet to the original phreatic tube in the ceiling. Sadly, this tube ended within 5 stations, choked with cemented mud and sandstone cobbles in the upstream direction, sealed by flowstone downstream. Unseen holes in the floor dropped rocks and mud balls down to the go-nowhere EFN canyon below. Without fanfare, our lead died, so we packed up and headed out. John derigged the traverse line and the two bolt climbs on the way back to HHA, which should be a big disappointment to all the "twenty footer" hounds.

After grabbing a bite to eat, we set off for some sight-seeing. We continued up the HHA trunk, ducked underneath the WVU bolt climb, and visited the Echo Dome(?) at end of the passage. I hit this beautiful dome with my disto and measured 101.4 feet to the top. We backtracked to see an area called Pristine, where John spied a potential bolt climb that he plans to do ASAP. Eventually, we made our way down to HHH so that Brian could meditate at the foot of the omnipresent "Buddha" in the Acoustic Persistence Chamber.

Eventually, we decided that we'd poked around long enough, and headed out of the cave. Again, the trip was uneventful, and we were on the surface by 1:30AM, with around 12.5 hours underground.

[trip] Return to SEC's Rushin' Rift

This GVKS weekend (2008-07-12), Nikki Green and I did a two-person "squeezefreak" trip to survey the upper passage at the top of the Rushin' Rift in Shovel Eater Cave. We were one of the last teams in cave, at around 10AM, and hit the tail-end of rope traffic in the entrance series of the cave. At HHA15 we picked up a 9mm rope, left a note for Mark Minton and Yvonne Droms (as a safety precaution for our two-person survey), and headed for the nearby Rushin' Rift. We found Bob Zimmerman's team before we found the Rift, and they stuck Nikki down two tiny leads which didn't go. They claimed to have checked out the Rift on the way in, and found it to be silent; we confirmed this ourselves, no sign at all of "The Devil's machinery", so apparently the water within this chasm is intermittent.

I rigged the 50 foot drop, though we did not rappel into it - rather we used the Y-hang as aid to go straight back into the upper rift passage. We shuffled back to the unlabeled calcite chunk cairn (CN1) which marked the end of the previous survey, located just before this passage goes from "small" to "tiny". Before we could mark our first station, the hungry rift ate our only roll of flagging tape; thus, all stations on this survey are marked with blue sharpie on rock.

This upper rift passage is capped by a fault plane, dipping about 20 degrees in a generally East direction, which frequently appears as a smoothly-sculpted calcite vein in the ceiling, and sometimes as oddly-shaped phreatic proto-passage formed within once-fractured rock. Freshly-broken crystal gives off a sulfur smell. An extremely narrow canyon is incised into the floor, usually too narrow to eat a body, but almost always the perfect size to eat the conveniently-placed foot or survey tape. At several places - notably near our first station and past our last station - rocks dropped down this canyon can be heard to tumble down quite an impressive distance, what I would estimate to be at or beyond 50 feet, though "tumbling rock" can be deceiving. At one point, we clearly heard hammering, which we later discovered to be the work of Bob Z's team. Airflow was never more than "slight", if that. Paleoflow direction is likely in the direction of our survey - away from the cave's main passage, and generally Northeast - at least in the upper rift.

We surveyed the entirety of what I "scooped" on the previous trip. I had estimated this to be on the order of 200 feet, but the miserable nature of the passage caused me to overestimate by 2X. At the end, the passage turns down the dip of the fault plane, losing around 15 feet of elevation, where the still-hungry rift devoured Nikki's digital camera (sorry, Nikki!). Finally a "room" is reached, which is comfortable enough for two people to stand and eat lunch; rocks dropped down here tumble down what sounds like a terrifyingly-deep chasm, an experiment that I repeated many times in the name of science. Beyond, the passage becomes too tight to follow, but the deep canyon may be accessible just beyond our last station, as the canyon widens in a sharp meander. Upon finishing, we de-rigged the unused rope and returned it to HHA15.

We surveyed 115 feet in a painful 10 shots. I do not consider the upper Rift lead to be killed yet. Rather, I believe that the only way to further explore the Rushin' Rift is to ignore the too-too-tight lower rift passage, and to rig rope from the top passage and enter the rift from one of these upper access points.

[trip] Shovel Eater Cave - Rushin' Rift

After heading down to Germany Valley late Friday night, through some of the thickest fog I've ever driven in, finding the field house dark and quiet upon arriving at 1:30AM, and getting a good night's sleep in my hammock underneath a torrential downpour, I met up with a large group of GVKS folks at The Gateway at 8AM Saturday morning. I was put on Bob Alderson's team with John Harman and Cullen Hencke, and our goal was to investigate a fascinating lead off of HHA, which was dubbed the Rushin' Rift upon its discovery on October 27, 2007. Mark Minton described it as:

Under one wall the canyon dropped down a deep, narrow pit which we named Rushin' Rift. A strange humming sound could be heard in the distance, unlike anything we had heard in a cave before. Air? Water? The Devil's machinery?


We arrived at the SEC entrance around 10:15AM and headed into the entrance series. After the third rappel, we ducked down under the water to a drippy, muddy room containing the new "Buckeye Bypass" (as we decided to call it). A short, uncomfortable, diagonal rappel to a rebelay drops you down to a series of traverses in a passage that looked vaguely familiar to me... the bypass seemingly teleports one all the way down and past Harper Canyon - wow! We were to HHA in no time at all, and were staring down into a complex intersection of narrow canyon passages off to the side of the "main" passage. Sure enough, when everyone was quiet, we could hear "The Devil's machinery" from the deep slot.

John and Bob cleaned the rock surface and set three bolts; a single bolt at the top for a traverse line down under the "lip" of the canyon, with two bolts for a free-hanging "Y" rig. We later taped this drop at 49.1 feet from the upper bolt. The rappel down is tight, with shoulders against the wall for most of the way, and should not be done while wearing a pack (oops!).

The lower canyon has a flat floor, is seldomly wider than 24 inches, and doesn't offer many (er, any?) opportunities to stand up. It is dry, with no sign of even a past stream, and with highly abrasive popcorn lining the walls and obscuring paleo-flow evidence. Upstream goes only 10 feet to a formation-obscured hole in the floor which was just a couple feet deep. Downstream the canyon twists in very tight meanders and appears to loop back on itself; when Bob pushed downstream I could hear him closely from the upstream hole. With extreme effort, Bob pushed downstream and had much difficulty returning. I followed and tried to "shave" popcorn from some of the squeezes for him to get back through. I did not attempt to push as far as he did, but I would guess that neither of us pushed farther than 40 feet from the rope.

In the lower canyon, we could definitely hear "The Devil's machinery", which sounded distinctly like a waterfall. I personally didn't think that it sounded louder after pushing in the downstream direction, but others in the party stated that they did. Having no luck pushing this tight, lower canyon, we decided instead to investigate the upper levels of the canyon. While Bob and I taped the drop, John and Cullen headed up and scouted it out.

The upper canyon, which is reached by traversing down to the Y-hang and going behind it, consists of an oval-shaped phreatic tube with a narrow canyon incised in its floor. It is bounded from above by a low-angle fault or fracture, which has been filled in with a band of calcite crystal. This calcite band has been solutionally sculpted in places to reveal a beautiful, "organic"-looking, flowing crystal ceiling. The upper passage follows the strike of this fault plane. It is very dry, showing small bits of gypsum in places, and is more comfortable to move in than the lower passage, though it is still relatively small passage. We were still able to hear the sound of water, off far in the distance somewhere but didn't seem to be any closer to it.

While Bob, John, and Cullen surveyed out of the upper canyon (from a point where the ceiling became quite low, marked by a cairn of calcite crystal), which yielded only around 50 feet of easy survey, I pushed in the upstream(?) direction, which seemed to correspond to what appeared to be downstream in the lower canyon. Confused yet? I pushed forward through alternating low-and-tight to narrow-and-tight to just-plain-tight tube with canyon or just canyon without floor (no actual exposure however), for what was probably 250 feet. At times I felt faint airflow coming up from the lower canyon, but it was never "blowing", even though I was in relatively constricted passage. After thoroughly shredding my cave suit on the dry, rough passage, it seemed to head down dip of the fault plane, going downhill (though I still believe upstream direction) approximately 10 feet. At this point, I could not hear the others, nor could I hear the sound of water at all. The passage isn't suitable for large cavers, but it does continue. I set a cairn here and turned back in time to run lead tape (read: get in the way) of the survey team.

We took a quick tourist trip to see Hellhole Hall, the Acoustic Persistence Chamber, and peer through the window at The Rubicon (WOW!). We were all stumped as to the origin of the sandstone cobbles in this wide, flat passage, and felt a sense of déjà vu as if this part of SEC belonged in some other Germany Valley cave...

The trip out was uneventful, and much shorter than my previous trip to this area thanks to the Buckeye Bypass. Even using the buckets to catch the dripping water, we still got a bit damp on the Bypass climb due to the large amount of rain this weekend, and also on the redirect climb above it. We exited the cave at 8:25PM, after a short 9.5 hour trip, to frigid 19 degree weather with a high wind; our cave suits froze on the walk to the vehicles, and several later teams reported that the locks on their cars had frozen solid!

I suppose that the lower canyon shouldn't be considered "dead", but it can probably go to the back burner unless no other route to the elusive "Devil's machinery" can be found. The upper canyon goes, but also requires "squeezefreaks" to map it, and doesn't appear to head closer to the sound. We surveyed approximately 50 feet, plus a 49 foot drop, but didn't solve the mystery of the Rushin' Rift. Thanks to my teammates for putting up with my sniffling and general slowness as I battled an annoying cold this weekend.
