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.

This 1/2-hour video begins with the Ice Age Floods impact on the Palouse area, then goes on with a fascinating oral and pictorial history of the area. The video was produced by Mortimore Productions for the Whitman County Library with materials and information provided by a bevy of contributors, including

National Geographic has published an outstanding article, “Formed by Megafloods, This Place Fooled Scientists for Decades”, about J Harlan Bretz and his outrageous, fantastical theories of a landscape shaped by huge floods. Most Ice Age Floods aficionados are generally aware of the story, but this one is so detailed and

Bluefish Caves directly challenged mainstream scientific thinking. Evidence had long suggested that humans first reached the Americas around 13,000 years ago, when Asian hunters crossed a now submerged landmass known as Beringia, which joined Siberia to Alaska and Yukon during the last ice age. From there, the migrants seemed to

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

Have you ever thought about the how the weight of the ice-age Cordilleran ice sheet might affect the underlying Earth’s crust. There is strong evidence that the crust was depressed hundreds of feet beneath the ice, and since the crust is relatively thin and rigid over a plastic aesthenosphere, that

Geologists have been investigating a potential cycle in geological events for a long time. A recent analysis on the ages of 89 well-understood geological events from the past 260 million years show a catastrophic 27.5 million year pulse in eight clusters of world-changing geologic events over geologically small timespans.
