Carroll Cave Survey Trip: Oct. 5, 2002
by: Rodney Tennyson
Jeanna Tennyson, myself, Jeremy King and Paul Woods were the second of
two survey teams that entered the cave. Having the rope rigged straight
down the middle of the dug shaft, I learned that should not sling anything
over your shoulder, but should have it hanging beneath you while on rope.
We were all soon on bottom, sopping wet from the dribbling spray that
cascades down the walls of the shaft. We only went a couple of hundred feet
from the entrance before beginning our survey of the upstream Thunder River
Passage.
This began off the T-Junction as a 30 ft. tall wildly meandering canyon,
12-20 ft. wide on the bottom and somewhat wider up high. The floor was
commonly bare limestone under 2-3 ft. of water. Mud is on every surface
above the water line, laid there by the occasional mega flood that must back
up from far down the main river passage.
Formations occured throughout the passage, but were usually just vague
shadows way up high, one fine example of a Showerhead formation occured
about 500 ft. upstream; where water was streaming out from the center of a
large conical drapery feature, growing from the inside out it seems. Too
bad I had gotten so wet coming in, a cloud of fog was following me
everywhere I went, and sure wouldn't have helped me to take pictures!
We mapped about 1100 ft. before the cold got to us, it was easy going
stuff, not much detail in a water-floored canyon that barely even had ledges
worth noting. The crossections were interesting however, and show more
about the passage than the plan does.
Ours' was a short trip, Jeanna's and mine's first. Much to Paul and
Jeremy's disappointment, once we finished surveying, we just wanted to
leave.
In short, we came, we surveyed, we got the hell out while the sun was
still warm! The dinner that evening was quite tasty and very filling.
