Lewis & Clark Landscape Ecology

from Columbia Gorge Discovery Center and Museum

Program image

This program explores the intersection of the landscape ecology of the Columbia
River Gorge with the Corps of Discovery’s journey over 200 years ago. It
examines how geological processes laid the foundation for the diverse
ecosystems of the Gorge, and the resulting resources the Corps of Discovery
utilized for food and trade as well as the challenges it faced in navigating
through the Gorge’s inclement terrain and weather. As they learn the geologic
and ecological story of the landscape from Celilo Falls to Beacon Rock and 
the journal writings left by the expedition participants, students will gain
appreciation for both the power of nature and the fortitude of the Lewis &
Clark Expedition.

Program Details


1. This program begins with dramatic readings from the Journals of Lewis and Clark, followed by an exploration of geography and ecosystems of the Gorge.
2. We then imagine how The Corps traveled through this area (by tippie-canoe mainly)
3. The geologic formation of Celilo Falls is described, and the Corps challenges there explored
4. The Rock Fort site is described, and why they felt they needed a fort
5. Why was "Windy Camp" windy and rainy?
6. What caused Cascade Rapids?
7. Why was this area a cultural divide and how did that impact Lewis and Clark and the Corps of Discovery?


At the end of this program, students should be able to:
•Describe how Lewis and Clark and the Corps of Discovery were challenged by the landforms in the Columbia River Gorge between Celilo Falls and Cascade Rapids.
•Understand the geologic story that formed the Columbia Plateau, Cascade Mountains and Columbia River Gorge.
•Describe the challenging weather Lewis and Clark experienced in The Gorge and learn what caused it.
•Describe how Gorge geography impacted the Corp's relationships with local native peoples at this trading hub
