Crevice Cave

Crevice Cave is not an archaeological site but rather a cave that penetrates up into the cliff along a fault breccia. A fossilized dune remnant that at one time completely sealed the cave is present within the cave and above on the cliff walls stretching to the cliff top. As at the other caves, the sealing of the cave by the dune likely triggered a rise in humidity, and the onset of speleothem formation, both of which are substantial. We have cut and sampled many of the flowstones and speleothems as well as the aeolianites to be used in paleoclimatic reconstruction.
