1st Trip: On 4/13/2003, Rod Horrocks led Dan Wray and Tim Moreland to the Amphitheater in the Historic Section where they discovered some black filamental iron fixing bacterial strands.
Trip Report: We went to the CM2 survey off the Amphitheater to start surveying the numerous leads that we found on a previous survey to the area. Starting at CM2R, we surveyed south into a virgin crawl. However, it reconnected to the CM2 survey after seven shots. We then went up to CM12E and surveyed SW past a rock covered with specimens collected in the 1890's and connected to station CM9. After shooting a shot into a dead-end room from CM8, we surveyed NW from CM8 towards a large blank area on the map. A choked passage continued west, but the main passage turned NE. This virgin passage has some nice mud crack curl ups. We mapped up a couple of parallel passages with the CM survey, tying into the C' survey at C18. We noticed that the CM and the C' surveys are actually in the same passage. I'll have to deal with this latter. We then surveyed up into a dome, where we connected to NB27. We ran out of time at this point. We surveyed 461 feet and left numerous leads along most of our surveys. Needs another trip.
P.S: At CM8, we found some very strange things. There is a small patch of black needles hanging straight down, about 1/2" in length. They look like an upside down pin cushion. Some of the larger needles, 1 1/2", have some web-like filamental loops and connections between them. Very interesting looking.
