Episode #052: Arizona's Meteor Crater and Monument Valley Erosion
5December 8, 2020
Summary
This episode explores the geological implications of the Meteor Crater impact in Arizona, referencing a pivotal 1997 paper by David Kring. The discussion extends to potential impacts from past cosmic events, with a focus on the Younger Dryas and its controversial theories. Field observations from previous trips highlight the dynamic erosional processes that may have shaped the landscapes we see today.
Key Takeaways
- 1David Kring's 1997 paper on the effects of the Meteor Crater blast wave.
- 2The estimated frequency of cosmic impacts occurring every 1600 years might be shorter.
- 3Discussion of Black Mat at Murray Springs and its significance.
- 4Petroglyphs at Chevelon Canyon explored for historical interpretations.
- 5Speculation over erosional processes in Monument Valley being more recent than believed.
