Tri-Cities Geology and Ice Age Floods

Wallula Gap

The geology of the Tri-Cities area is very unique in that it consists of a basalt and lava landscape carved by the great Ice Age Floods. During the largest floods the Tri-Cities lay under 900 feet of floodwater (i.e., Lake Lewis) that backed up behind the hydraulic constriction at Wallula Gap. During this time the tops of the local hills (e.g., Badger and Candy Mountains) were "islands" poking out above Lake Lewis. The floods also carved the basalt and lava landscape to create the Channeled Scablands in Eastern Washington.

You will find information about the Ice Age Floods on this page by two Tri-Citians, Bruce Bjornstad and Tom Foster, along with information about the Lake Lewis Chapter of the Ice Age Floods Institute, based in the Tri-Cities. Additional resources about the Ice Age Floods, Columbia River Basalt Group, and Channeled Scablands of Eastern Washington are also provided.

Ice Age Floods Institute & Lake Lewis Chapter

Ice Age Floods Institute

About the Ice Age Floods Institute

The Ice Age Floods Institute (IAFI) is a nonprofit, volunteer-based organization that is committed to the recognition and presentation of the Ice Age Floods as a significant part of the nation's, and the world's, natural heritage. You can find excellent resources (books, maps, videos, etc.) related to the Ice Age Floods.

IAFI is committed to working with Congress to support the National Park Service's effort to form the Ice Age Floods National Geologic Trail which would essentially be a network of marked touring routes extending across parts of Montana, Idaho, Washington, and Oregon, with several special interpretive centers located across the region.

Lake Lewis Chapter of the Ice Age Floods Institute - Tri-Cities

The Lake Lewis Chapter of the Ice Age Floods Institute represents the Tri-Cities area and south-central and southeastern Washington and the adjacent areas in Idaho and Oregon.

The Lake Lewis Chapter offers lectures and field trips in the Tri-Cities region that are open to the public. In addition, this chapter has published the Lake Lewis Floodscape Brochure that includes a map of the region and several short articles about not-to-be-missed Ice Age floods features.

Ice Age Floods Glossary of Technical Terms

A Glossary of Technical Terms Related to the Ice Age Floods was prepared by the Ice Age Floods Institute to help people of all backgrounds understand the geologic terms used to explain phenomena related to the Ice Age Floods.
