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.

No one can ever say for sure what the future will bring, but this new video has summed up all the science-backed predictions that we can reasonably make about how Earth will change over the next 1 billion years. It’s highly unlikely that anyone will be around to see most
