2016 Glaciers, Plutons and Geopolitics of Grayback
Instructor: John Roth
Date: Sunday, July 31, 2016
Location: Meet at SFI, Selma, OR
The Grayback is a stitching pluton, a granitic weld riveting together two great rock slabs that --with over a dozen other seafloors -- make up the Klamaths. Learn the latest research about how plutons evolve, and what this says about glaciers. (Find out why a “plutocracy” is the best government money can buy!) Participants will learn to identify twenty glacial features and types of plutonic rocks with simple methods as we visit Rattlesnake Creek and Bigelow Lake at the Oregon Caves National Monument and Preserve.
