Recently there was long thread about the BCA. I can now post possible answers to some of the questions, such as "Why is the BCA still raising membership prices when there is a significant amount still left in its coffers?"
Yeh that's been on before, but that's rather cool. I guess the sandstone is more sandstone limestone as they say it dissolves, maybe it's glued together with limestone?
Looks like a big cave anyways, I would love to visit and explore the area.

Quartzite, actually. This is only marginally soluble, so the caves form over tens of million years, rather then tens of thousands years which is more typical of normal karst.
