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.

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

This feature-filled video by Tom Foster and Nick Zentner explores the evidence for Glacial Lake Missoula, and provides a treasure trove of places to visit and sights to see when you plan your field trip to the area.

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

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. This 2016 video, produced by reputable sources, doesn’t answer that question, but it is an interesting and instructive visualization of human

Palagonite Maar Just west of Hood River is a distinctive, short (<500 m) section of stratified orangeish oxidized volcanic tephra and highly fractured lava bombs. This mixture of oxidized volcanic particles ranging down to sub-micrometer sizes mixed with the larger lava bombs is a palagonite tuff. This deposit is the result of a “phreatic” eruption when lava erupted explosively
