Speaker: Dr. Jon Harvey, Fort Lewis College
Talk: Repeat 3-D surveying of the Missionary Ridge Rockfall reveals dynamics of an evolving geohazard
The March 2020 Newsletter highlights Dr. Jon Harvey’s UAV surveys of the Missionary Ridge rockfall, which evolved through spring-driven scarp failure, debris buildup, and a 2019 dam break that sent major flows downslope. Prez Sabina Kraushaar reports the March meeting’s COVID 19 postponement, introduces President Elect candidate David Schiowitz, and thanks board and field trip volunteers. Upcoming field trips: Harding Pegmatite Mine and Cedar Mesa Sandstone.
