IAFI Events
Explore and Discover How Our Amazing Region was Formed!
Field Trips, Presentations and Other Events are designed to educate, entertain and leave you with a sense of “wow” along with providing fascinating information about the Ice Age Floods.







Ice Age Floods Institute Events Inspire, Encourage Exploration, Offer Friendship and Involvement
Field Trips and Hikes are led by amateur and professional Geologists with new and amazing information to share. They are fun, exciting and informative outdoor adventures for the entire Family to enjoy!
Visit our Activities Event Calendar below for IAFI Field Trips, Hikes and other activities in your area, and go have a great time!



We offer indoor Presentations, especially popular when heat or cold make outdoor Field Trips too uncertain or uncomfortable. Many Presentations are available via Zoom.
We also offer programs for schools, senior centers and similar organizations to educate and stimulate minds about the Ice Age Floods.



Other Events such as meetings, festivals, conventions and gatherings, with various public and private organizations, help us tell the story of the Ice Age Floods, Geology, Wildlife and History.
We often have our ‘Store in a Box‘ at these types of events where people can view and purchase IAFI merchandise.

There is considerable controversy regarding when humans first migrated into the Americas and whether they might have been in the local area during any of the Ice Age Floods.

On October 7th at Chief Timothy Park near Clarkston, WA at the latest Confluence Story Gathering, Thomas Morning Owl (Umatilla tribe) noted there are indigenous people’s stories of massive floods going back to 14,000 years ago. While he didn’t elaborate, it would be very interesting to have these stories shared as first-hand

Chris Goodell’s 1-hour video presentation of his Ice Age Flood hydraulic modeling is both enlightening and thought provoking. Chris is a hydraulic modeling professional for Kleinschmidt Group, whose personal interest in the Ice Age Floods phenomenon led him to privately undertake HEC-RAS modeling of a possible Ice Age Flood hydraulic

In September 2021 my wife and I took a trip to see what was new along the Ice Age Floods National Geologic Trail and visit some places we did not make it to in our very first trip in 2004. The IAFI chapter brochures were very helpful in learning what

Lake Missoula filled many times and emptied catastrophically in many Missoula Floods. Rhythmite sequences [a series of repeated beds of similar origin] at numerous localities provide this evidence: slack-water rhythmites in backflooded tributary valleys below the dam indicate multiple floods, and varved rhythmites in Lake Missoula attest to multiple fillings
