Columbia Gorge

Meet OMSI Outdoor Science Education instructors on location for the hands-on, interactive programming that makes our outdoor science schools so popular. Schools are responsible for transportation to and from sites, chaperones at a 1:8 ratio and lunch.

Hike the beautiful Columbia River Gorge with an OMSI naturalist. Learn geology basics like plate tectonics, rock cycle, erosion and deposition through magnificent geologic events in Pacific Northwest history. The class will focus on the formation of the Cascade Mountain range, the Columbia River basalts and the effects of the Missoula Floods on the Columbia River Gorge.

A minimum of 2 weeks' advance notice is required for all registration requests. If you have questions, please contact us at 503.797.4661 or
