In 1963, a core drilling team was taking samples for I-35. ; 40 feet underground their drill bit broke into a massive air space, surprising the team when the drill bit then dropped to the ground in the air space.... So the skinniest guy on the team was lowered through a hole less than 3 ft in diameter, and found Innerspace Caverns, apparently the 4th largest cavern in Texas. Usually around 72 degrees, 90% humidity. ; No tripods allowed, and portions of the cavern have flooded at times...and is also the home of prehistoric sinkholes - they have recovered the bones of many prehistoric animals here after they got trapped in the sinkhole, dropped into the cavern, pitch black, with no food.

Roger, woud you give us the Exif data on those shots and the lens you used? Thanks! ; The colors are beautiful and the formations very erie. ; I would not have wanted to be the guy that was first lowered down. ; Might have been a real Lost World down there. ;
Here's one from a "dig site" ; (not active, they left the setup there for show, they quit digging after they kept finding the same 50 animals' bones over and over....) A closer view at some soda straws:
That is amazing! This place seems so cool. Is it seriously cramped spaces or is there a lot of room to move around?
The main tour is designed for almost everybody...there are one or two places where the hallway is only about 5, 5.5 ft tall, so I had to duck. ; They do offer other tours of the cavern that isn't as easy to get to.
Few more: Right below this formation is a natural low spot in the cavern, which flooded enough to swim in 2 years ago during the high rains - so they had to shut down half the tour, and allowed employees to swim. Moon Lake: This is actually the end of the standard tour, where you have to turn around and go back.
