[trip] New Deckers Creek Cave Survey

This Sunday, John Harman, John Cunningham, and I (Dave Riggs) surveyed the new cave near Deckers Creek. We spent about 3 hours surveying, shot 11 shots, including two surface shots in the entrance sink. The cave is 65 feet long and 27 feet deep; the total slope length of our in-cave survey was 99.5 feet. This was John C's first survey trip, and he did great - they didn't have to re-shoot a single shot. It was my first time doing a real sketch, and I can't say that I did as well as the instrument readers - I'm going back next Sunday with a lineplot to re-do my sketch properly!

John C. chimneyed up to the very top of the crevice passage and found that it goes to the very top of the limestone, there is literally topsoil at the ceiling. We moved a few rocks and opened up a second "entrance" to the cave, a 9 inch wide and high joint which intersects the top of the crevice passage. It was large enough to survey through for a single closed loop, but you'd have to be seriously determined to actually go into the cave that way.

Working names for the cave are "One Room Wonder" and "Three Turkeys", the latter name being a double-play on the three wild turkeys that tried to scoop our cave that afternoon, and on the "three turkeys" who surveyed it.
