I have spent very little time in Caracas, Venezuela, but here is a pic.
On the tepui, we were landing helicopters with gear and people. A shot of Joyce Lundberg, a research leader, topside as the helicopters came in.
Set up a photo here, and water was calm. While waiting for my flash holder and model, the water started to rise. Water rising in a cave is not a good thing for those in the cave. We bolted for the entrance and were glad we did, as the water continued to rise and we would have been dead or trapped had we not exited promptly. But I have almost no really good cave photos as this was my one opportunity. You make the call, dead, trapped or some awesome shots of people nearly dead or trapped in a cave flood. I made the call that we get the heck out of there, and the others agreed. So a picture of a stream passage in Charles Brewer Cave as the water was rising. Side note, it rose many feet after we got out of the cave. We made the right decision at the right time.
This is a bizarre mix of formations coming off a giant breakdown block on the floor. There are formations coming off the breakdown block, with interesting detail, yet there is this large, unexplained white bit with a lot of formation growth on it as well. The ruler in the pic is six inches long for scale, but in general, still notes more research needs done on these caves to figure out the geology. These are silica formations, not calcite like in typical caves.
