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.

Richard Waitt kindly shared his recent paper published June 2016 in Quaternary Research, titled “Megafloods and Clovis cache at Wenatchee, WA.” “It covers the reach mainly from Chelan Falls to below West Bar, tries to tell the story of sequential megafloods coming to Wenatchee area by different routes at different

In August, Scott David, a postdoctoral researcher and Karin Lehnigk, a 2nd year PhD candidate from the University of Massachusetts visited the scablands for a week to do field studies. Karin was in search of granite erratics. Samples of these were taken to be processed for Beryllium-10 exposure dating, a

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. This

The Washington Geological Survey (formerly the Division of Geology and Earth Resources) has just released an ESRI story map about the Ice Age Floods in Washington. The story map: “tells the story of cataclysmic outburst floods that shaped the landscape of the Pacific Northwest during the last ice age. With

“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

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

Spring may have been when a roughly seven-mile-wide asteroid struck the Earth, immediately triggering the mass extinction that would wipe out 76 percent of known species. That key piece of timing doesn’t come from dinosaurs, but from the fish that swam in the waters dinosaurs drank from. By studying the
