How to Beat Down Surveyors (or How to Knock Off Fourteen Leads)

We had had a wonderfully productive survey trip last December in Hancock Cave, but then the rains and snow melt kept us from passing through the Funnel Tunnel for many months. On August 11, Dave Duguid and Will Summer joined me for another survey trip into Hancock Cave. This time we meant business. I knew that when Dave vigorously started widening the Funnel Tunnel to a size that allowed Will and me through (Tanya loaned us a great shovel).

I was really impressed that Dave and Will had their readings agree right from the start. There was a little bit of grumbling when I suggested they always choose passages to the right (because it was more likely to lead away from known cave), but they went along. The first right passage turned into a decorated stoopway but widened out before it joined in with a walking passage.

The end of the walking passage found us in several short domes, including the highest point beyond the Funnel Tunnel (almost 33 feet above the cave entrance). After surveying the domes, Dave discovered a survey marker we left in the 1990s. When I pulled out all of my notes, I realized that we had discovered the back way into the famed Noogah, closing a really big loop.

There were several leads in the Noogah area that we knocked off the map from there. One involved a climb up to a mouse nest with six mice surprised be Dave's visit. Another low lead was too small for me, but Dave pushed his body through and sketched the room. We looped up and down to close some other loops in that area. The remaining lead in the Noogah area involves a high step-across onto an iffy rock, and we chose to save that one for a fresher start.

Instead we went back near the beginning of our survey that day and surveyed down a long water-sculpted passage with at least one shot over forty feet long. Dave and Will liked these long shots, so I next to them to the other side of the main passage to mop up the dry stream leads. It was easy surveying for Will, but Dave was the one who had to drag tape from one station to the next. Will and I just walked around in the main passage.

Nearest the Funnel Tunnel the stream passage got extremely low. Dave couldn't even drag his body along the cobble after a certain point. Fortunately we could visually connect the stations from both sides, so I'll be able to sketch that to the final map.

It was late when we got out, so we were stuck with the Pizza Hut. One would think that the only customers in the restaurant could've been fed in less than 50 minutes, but the staff seemed to be in no hurry. Around 12:30 AM, we bedded down at Tanya's.

Dave, Will, and I managed to survey 760 feet of passage on that trip with more than fifty shots. Everyone knows that Hancock Cave is the longest surveyed cave in Smyth County, Virginia. The surveyed passage is now up to 2.33 miles in length (depth of 170.5 feet) for the survey we began in December 1996. This length means that Hancock is now longer than Patton Cave (2.040 mi), Buchanan Saltpeter Cave (2.060 mi), Clover Hollow (2.103), Cave of the Winds (2.147 mi), Cave Mountain Cave (2.200 mi), Kennamer (2.326 mi), and Sinnett-Thorn Mountain Cave (2.329 mi). It's approaching the lengths of Trout, Fletcher, Ape, and Low Moor Caves, but there are only about seven leads left to explore this fall.

The Deal, Survey Style

Anxious to continue sketching Rowland’s, Ken and I stuck a familiar deal. I would help him in Hancock if he helped me in Rowland’s. A date was selected; we set out to find others to assist; Will helped us on Saturday and Tanya and Robbie on Sunday.

Hancock

After a home cooked breakfast, thanks to Ken, we set out for Hancock. Ken had a plan already in place; the leads he was interested in were past the funnel tunnel. The funnel tunnel can only be passed when there hasn’t been, nor will there be, rain. Obvious to most all, the southeast is under near drought conditions.

Even though Hancock is currently over two miles in length, getting to our initial lead did not take long. The lead took us generally north and not into anything very tight. The lead eventually took us into a room that had been surveyed to via another direction; closing off another lead on Ken’s list.

While in the general area Ken had a few other leads. One high lead led into a formation choke; through the formations gray field mice could be seen milling around. One of the leads seemed very promising but in the end looped back to the room we had surveyed to earlier. There was one high lead, with a deep crag below, that I opted out of; it might be more appealing as the first lead on fresh legs.

Ken had one more lead to survey, a low stream passage; and the correct motivation, another home-prepared breakfast if we could break 750ft of surveyed passage. With 50ft to go, who could resist! I pushed in, however low meant really low. While lying on the bed of mud-glued coble stone, trying to dig it up, I simply called it quits. We surveyed what we could; fortunately it amounted to more than 50ft.

We exited the cave around 10:15 to a hot, humid, sound invested night. Receiving very low service at Pizza Hut landed us back at Tanya’s around 12:30. Keeping to his word, Ken made breakfast the following morning.

Rowland Spring

Pulling up to the owner’s house we were rewarded with a bit of information. On the last trip we found a signature in the cave; asking the owner if he knew any of the names, a gentleman standing next to him confessed to being one of the guilty party. The individual provided details of using a rope and climbing hand over hand through the known pit; all the wild speculation of how the signature got there came crashing to an end.

Rowland’s is not a large cave at this point, however to get back to the survey area takes some time. There’s a series of climbs and of course a pit to drop. There was no water in the stream and the mud exceptionally sticky.

The start of the survey immediately put us into a large room, which we never surveyed out of. I don’t think we surveyed but thirty percent of the room. The room is very impressive; it is difficult to define where the walls are, our lights where not bright enough to penetrate to the opposite side. The room has very large blocks of breakdown making traversing the room quite interesting.

The survey tally for the day was 416ft; the remainder of the room waits to be surveyed and any leads off of the room.
