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.

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

Balbas et. al. use cosmogenic beryllium-10 dating methods to further constrain the timing of ice sheet retreat, as well as the potential pathways for megafloods from both Lake Missoula and Lake Columbia. Read this fascinating Geology article summarizing their findings. Balbas2017 – Missoula Flood Chronology In summary, our new chronological

Robert Frost finished his poem “The Road Not Taken” with this verse: I shall be telling this with a sigh Somewhere ages and ages hence: Two roads diverged in a wood, and I— I took the one less traveled by, And that has made all the difference. As our President Gary Ford has

Check out this 2-Minute Geology expedition with Nick Zentner and Tom Foster exploring the Giant Current Ripples at West Bar and Camas Prairie. Ice age floodwater 650 feet deep – moving at 65 miles per hour – left Giant Current Ripples along the Columbia River at West Bar! The ripples

Check out Bruce Bjornstad’s Ice Age Floodscapes YouTube channel. A growing library of surreal aerial video and pics of other-worldly megaflood features.These drone videos and images that can only be achieved and appreiciated from close range in the air give a unique perspective on large landscape features, such as: Gardena Cliffs Rhythmites, Streamlined

Using detailed fossil comparison techniques, scientists have been able to identify a giant new saber-toothed cat species, Machairodus lahayishupup, which would have prowled around the open spaces of North America between 5 and 9 million years ago. One of the biggest cats ever discovered, M. lahayishupup is estimated in this new

New research reveals the ancient animals survived some 8,000 years later than previously thought Frozen soil samples collected around a decade ago are rewriting our understanding of iconic Ice Age animals like the woolly mammoth. The soil samples were pulled from Canada’s permafrost in the early 2010s, but no work

An ancient flood seems to have stalled the circulation of the oceans, plunging the Northern Hemisphere into a millennium of near-glacial conditions. Thirteen thousand years ago, an ice age was ending, the Earth was warming, the oceans were rising. Then something strange happened – the Northern Hemisphere suddenly became much
