As others have already intoned, amazing stuff.  What are Tufa layers?


A type of limestone which forms exclusively underwater. There's lots of tufa in the American Southwest (which was once mostly underwater in a vast inland sea) -- the Anasazi people used to burrow into cliff walls which were essentially tufa in order to create cliff-dwellings.

All the cliff dwellings I have seen are in sandstone. Not tufa which is calcium carbonate.
