Geologic Discovery Field Trip High Lava Plains
September 14 @ 7:45 am - 6:00 pm$50.00
In this day-long geology field trip Saturday, September 14, 2019, with geology professor Steve Carlson, students will engage in experiential learning at investigative sites to analyze specific features of Central Oregon’s high lava plains that tell the story of the geologic past. The West Coast of North America is an active Continental Margin. Large-Scale geological processes involving horizontal and vertical motions of the outmost layers of the earth cause earthquakes volcanic eruptions and the uplift of mountains. The rocks and landscapes that one sees while driving between The Dalles and Sunriver are nearly all related, in one fashion or another, to volcanism. At the end of this course, students will understand how the Miocene Lavas were produced, the development of the High Cascade volcanoes and associated Cascade platform of the western and central Cascade system, and will be able to apply volcanic theories explaining shape, explosiveness, and features to the high lava plains. This excursion begins in The Dalles and travels south through Cove Palisades and Smith Rock State Parks and several other points of interest before culminating at Criterion Summit and Sherars Falls.
Meet in front of the museum at 7:45 for the 8 a.m. departure. Return is estimated at 6 p.m. The $50 fee per person includes a boxed lunch and water. Please wear sturdy walking shoes.
For tickets or information, phone (541) 296-8600 x 201, or buy your ticket online. Please register by September 12.
