AAPG Total Solar Eclipse Seminar and K-T Boundary/Impact Crater Field Trip Guide, Casper, Wyoming – August 18-22, 2017

This Seminar and Field-Trip Guide was compiled by Doug Cook who gathered the materials discussed during this Seminar and Field Trip. The primary objective of the seminar was to observe the total solar eclipse that passed over the Casper, Wyoming area. Side field trips were also taken to observe impact craters and K-T boundary in outcrop.

Jack Schmitt and Jim Reilly, whose tireless participation and enthusiasm in AAPG’s Committee on Astrogeology, provided their professional perspectives and expertise on the subjects at hand.

Kent Sundell, Casper College, and staff and students contributed to the organizing, guiding, and operations of the field trips in this Seminar.

Don Clarke and Doug Cook, whose eclipse experience, ideas, and Casper connections were the catalyst for the AAPG Eclipse Seminar.

Karl Osvald provided contributions of knowledge on Wyoming astrogeology at the Douglas impact site and Linch/Sussex K/T Boundary sites (more).

Henry Wise and Michael Campbell have added subsequent work on the K-T and impact-crater samples that Wise obtained during the Field Trip. They conducted a preliminary thin-section analysis and literature search. They have attached a preliminary report to the end of the document, (here). Additional activities are anticipated.
