Ice Age FloodFest 2025 – Sat. July 26th

Get ready for the Ice Age Floodfest 2025 on July 26th, an unparalleled celebration of the cataclysmic events that carved out the Pacific Northwest’s iconic channeled scablands! Dive deep into the geological story that spans millennia and reshaped the very landscape beneath our feet. From towering coulees to vast dry falls, the evidence of these ancient, colossal floods is everywhere, and this year’s Floodfest promises to raise your awareness and understanding of their incredible power and lasting impact.

Join us in the Lower Grand Coulee for a day of expert-led talks, fascinating field trips, and engaging exhibits that will transport you back to a time when mile-high ice dams burst, unleashing torrents of water that dwarfed any flood in human history. Whether you’re a seasoned geologist or simply curious about the natural wonders around you, the Ice Age Floodfest 2025 is an event you won’t want to miss! Presenters will share their knowledge and their appreciation of  Ice Age Floods Geology, the Channeled Scablands, Shrub  Steppe Ecosystems, Anthropology, Archeology, and History.
