Very nice read. Carlsbad was/is one of my favorite public caves because they let you wander through it at your own pace. The phreatic sponge work development is particularly spectacular. It also intrigues me that sulfuric acid speleogenesis may be microbially mediated. Do you think that is the case generally, including for Carlsbad?

Thanks for the heads up on the Engel et al paper...I missed it but am definitely going to take a look.
