PBS-SEPM 2021 May Luncheon & Annual Meeting - Carol Hill




Presented by Carol A. Hill at the May Luncheon and Annual Meeting of the Permian Basin Section-SEPM

ABSTRACT:  There are three profound mysteries involving the origin of Grand Canyon:  (1) How old is Grand Canyon – is it old (~85 Ma) or young (~6 Ma)?;  (2) How did the Colorado River cross the topographic high of the Kaibab arch – water cannot flow uphill?;  and (3) How could the Colorado River have become “lost” through Glen Canyon and Grand Canyon – there is no trace of it from the Utah-Colorado border to the mouth of the canyon from ca. 11 Ma to 5.5 Ma.  This is the story of our 20+ year Grand Canyon project that has tried to solve these three mysteries from our knowledge of caves and karst.  It starts from the time of writing my Carlsbad Cavern book (1986) and my Geology of Delaware Basin book (1996), and it continues to the present.  It focuses on Grand Canyon caves, and you will see lots of beautiful Grand Canyon and Grand Canyon cave photos as I tell this story.
