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.

I’ve found there is huge public interest and concern about the catastrophic effects of the Eagle Creek Fire on the Columbia River Gorge. Pictures of ridgeline after ridgeline enveloped in bright orange fire, trees bursting into towering flames, and the choking smoke that filled valleys throughout the Pacific Northwest are

Millions of people who visit and pass through the Gorge each year don’t realize the scope of the cataclysmic stories behind the stunning and tranquil beauty they are surrounded by. The Spring 2019 edition of The Gorge Magazine (page 50) attempts to address that premise with a feature article about

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

Washington State Geological Survey is collecting, analyzing, and publicly distributing detailed information about our state’s geology using the best available technology – LIDAR – an acronym for Light Detection And Ranging. The main focus of this new push for LIDAR collection is to map landslides, but there are innumerable additional benefits

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

The Washington Geological Survey (WGS) has released 50 high-resolution lidar-derived images of the State’s geology and geomorphology through the Washington State DNR’s Flickr page. The images are available in 16:9 format (7,200 x 4,050 pixels) and 4:3 format (7,200 x 5,400 pixels). Ten of the images are new (see below)

In March, while visiting San Diego, I went to the San Diego Museum of Natural History in Balboa Park and toured the remarkable Cerutti Mastodon Site exhibit. This controversial exhibit of a mastodon site is notable for its claim that the mastodon’s bones were broken by humans 130,000 years ago,

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
