Day three was spent examining the sedimentology, structure and paleontology, and a bit of the wildlife biology at Owl Canyon. We even stopped at the Payless Shoestore in nearby Barstow (Dr. Wilson’s hometown).

Dr. Judge explains to the group how during a time of tectonic extension large-scale folding can develop. This was the last stop of the day at Calico Ghost Town.
