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.

Do you ever hear the Led Zepplin song “Kashmir” in your head when contemplating the Ice Age Floods? “I am a traveler of both time and space. To be where I have been” –Robert Plant, Led Zepplin’s Kashmir My 11-year old daughter and I are on a 5-day, 4-night raft

Analysis of how long erratics have been exposed on ice-free ground in the hypothesized “Late Pleistocene ice-free corridor migration route” suggests that route was not fully open until about 13,800 years ago, and the ice sheets “may have been 1,500 to 3,000 feet (455 to 910 m) high in the

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

“Beneath Our Feet: Mapping the World Below” plumbs the depths of the question, “What’s beneath our feet?” through maps, images and archaeological artifacts. The exhibition explores nearly 400 years of maps and objects in an attempt to find out why and how humans imagine subterranean landscapes including caves, mines and

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

The Columbia River Gorge is an incredibly popular area to visit, and that’s for good reason, the setting is uniquely spectacular. The Gorge encompasses: Easily accessible ecozones that range through boreal conifer forests, oak woodlands, high desert grasslands and alpine environments in only 40 miles, Dazzling viewpoints and scenery, including

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

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
