Floods, Fish, and Formations: A Field Trip to the Columbia Gorge

Designed for school groups, homeschool students and pods, this field trip will take us to the Columbia Gorge to learn the fascinating story behind how lava and ice shaped what we see today, the life cycle of salmon, and more!


Choose a hike where we will have a closer look at the variety of plants and interpret the story held in the rocks we find. Learn about the natural history of salmon and what adaptations make these fish so unique as we observe migrating salmon. Visit Bonneville Fish Hatchery where we will discuss some of the challenges salmon face along with what we can do to help protect them, making sure to save time to say hi to the massive Herman the Sturgeon.

A skilled Portland Audubon Naturalist will take you on a 5-7 hour program leading a field day experience in the beautiful Columbia River Gorge that you and your students will never forget!
