Geo 1095: March 1, Day 790: Drapery Regenesis

This spot is apparently called Angel Falls (page 22 of this PDF). The photographic tour doesn't mention it, so I'm speculating here, but that broken drape near the center, with the large, regrown, bright white stalactite, looks as if it might be more souvenir collecting, with the regrowth occurring in the past century or so. As we saw earlier, though, natural processes can also break these speleothems in the absence of human defacement, so that must be considered as another possibility. We're also getting close to the artificial addit of the exit tunnel, which means air flow patterns have changed in historical times. Sometime in the near future, I need to get on it and explain why airflow (among other issues) is so important. However, it feels like this entire year so far (that is, the last couple of months) has been a struggle to keep up: a Red Queen's race, where I have to run as fast as I can just to stay in place. It does not bode well for online stuff as the field season approaches...

Photo unmodified. May 9, 2013. FlashEarth Location. (Since we're underground, I have only a vague idea where this is with respect to the surface.)
