COULEE CITY — Just about anything anyone could want to know about the Columbia Basin will be on display Saturday at the Ice Age Floodfest at Sun Lakes-Dry Falls State Park.

“Floodfest is a gathering of ‘ologists,’” said Washington State Parks Interpretive Specialist David McWalter. “We’ve got archaeologists, geologists, geomorphologists, biologists, historians.”

The lineup for Floodfest is like a who’s who of experts on the region, according to Washington State Parks’ schedule for the event. Cascadia Conservation District Archaeologist Mark Amara will have a booth to highlight the importance of historical artifacts, tools of the trade and hands-on activity. Two other conservation districts – Columbia Basin, based in Moses Lake, and Foster Creek, based in Waterville – will offer programs on shrub steppe ecology, soil, water and natural vegetation. Local authors Dan Bolyard and John M. Kemple will talk about European American history in the region, and Colville Confederated Tribes Historian Lucy Stanger will have historic photos and information about the tribes who have inhabited the area from time immemorial.

On the geological side, the Ice Age Floods Institute will have a 3-D map of Oregon, Idaho, Montana and Washington, and the National Park Service will bring the Ice Age Floods National Geologic Trail mobile visitor center. Retired educator Janice Elvidge will present the River Mile Network, demonstrating the importance of water ecology and healthy watersheds using crawdads, McWalter said.

There will be activities for younger visitors as well, McWalter said.

“(Amara) has a kiddie pool that we fill with different artifacts that kids can sift through and use the tools of the trade for archaeological digging,” McWalter said. “We are doing a thing called ‘Impressions of the Park’ where kids draw and do arts and crafts.”

The Coulee City Library will have children’s activities as well, according to the State Parks schedule.

For the people who want something a little more active, there will be a gentle guided hike to Umatilla Rock at Sun Lakes-Dry Falls State Park, with sweeping views of Dry Falls and the landscape carved by the retreating ice 15,000-18,000 years ago.

Because the Dry Falls Visitor Center is undergoing renovations, Floodfest has been relocated to the amphitheater at Sun Lakes-Dry Falls State Park, McWalter said.

Visitors won’t need to have a lot of knowledge ahead of time about the sciences and history at Floodfest, McWalter said.

“You can go as in-depth as you like or as superficially as you like,” he said. “My fellow interpreters and I are trained to do education programs from university level all the way down to kindergartners. The whole goal is to help people learn (about) and appreciate the places they call home.”
