Continuation of Rowland Spring Cave Survey

Diana and I left Durham around 2:30 on Saturday amidst one of the more beautiful sunny days we’ve had in some time; the weekend was to be so nice there was a brief right side / left side struggle in my brain. Perhaps the weekend would be better spent outside than underground. But the desire to connect the two entrances prevailed, even if we had to connect the two by a surface survey.

Getting into Marion around suppertime was a pleasant variation to most trips. It was nice to enjoy a relaxing dinner and conversation with Tanya, and still get to sleep before 11pm. I even got a chance to walk Tanya’s dog, Daisy, that evening before the sunset. Our start was a bit slow on Sunday, but after breakfast we rolled out toward Rowland Spring.

The plan was to continue to survey in the upper entrance. There were two leads to complete before trying to figure out how to navigate into the lower section. And, of course, to leave ample time to perform an overland survey should it be necessary.

We started the survey off of station C20 that lead us generally west for a few shots before ending. We proceeded to the lead off of station C12, leading general southeast. There were several deep rim stone dams along this passage, and a formation choke that was blowing copious amounts of air; I would guess air from outside based on the location.

The second lead brought us back to the hole in the floor that leads to the lower section. Since Diana and I brought our vertical gear we decided it would be better to drop the vertical section and determine the best route to safely get all cavers to the lower level.

As Diana prepared to drop the pit, the airflow passing though was clearly evident by Diana’s carbide flame curling in the direction of the pit regardless of which way she faced. The pit ended up being much deeper than expected, 48ft to be exact. I was going to drop the pit and help her look for the lower entrance climb; but she found the station left from survey B quickly. We opted to pass Diana the cable ladder and rig the other side. Tanya and myself cleaned up our gear and left for the lower entrance.

Upon getting to the climb, there awaited the cable ladder. Soon we were all in an enormous room. From this room we were able to detect the sound of the stream on the northwest side of the room. While taking a break; I checked out a possible lead to the north of the room and found continuing passage, and a dead possum.

Getting back to the survey, we had the task of trying to sketch the room. We started with the south end since it appears to have no going leads. It wasn’t long though before the continuous airflow in this room chilled us to the bone. We opted to connect the two entrances and call it a day.

We surveyed 292ft of passage, with only one set of instruments…that is another story. The surveyed passage is now over 1000ft and has a vertical drop of 116ft. The most significant statistic though, there is more cave to be surveyed!
