We head back to Meteor Crater and dig into the definitive 1997 paper by David Kring on the effects of the blast wave from the central Arizona impact 50,000 years ago. Much was learned from the detonations of nuclear weapons during the 1950’s, with numerous craters blasted out in the Yucca Flats of Nevada. The estimates for a similar event every 1600 years are pondered, and we figure that those periods are considered to be even shorter now. Then we revisit a few other spots from our “Southwest Experience” in October, including a stop to see the distinct Black Mat at Murray Springs, petroglyphs at Chevelon Canyon, and Monument Valley – where the “Great Denudation” begs for questions about the erosional processes that shaped those landscapes, and the history of seismicity that should’ve toppled the fragile sandstone spires long ago. Unless of course, that those erosional processed occurred much more recently than previously imagined…   CBD RECOMMENDED - Listen to Randall’s experience with “CBD from the gods” after the mid-break at 48:43.
