Waucoma Bookstore and the Columbia Gorge chapter of the Ice Age Floods Institute are hosting author and geologist Bruce Bjornstad for a presentation on his new book On the Trail of the Ice Age Floods, Northern Reach: A Geological Field Guide to Northern Idaho and the Channeled Scabland.
The presentation will be on Sunday, Sept. 23, at 2 p.m. in the meeting room at the Hood River County Library (502 State St., Hood River).
Following up on his first volume, On the Trail of the Ice Age Floods: A geological field guide to the Mid-Columbia Basin, geologist Bruce Bjornstad joined forces with colleague Eugene Kiver to guide readers upstream -- northward into the Channeled Scabland and northern Idaho.
The authors explore numerous flood features and present dozens of trails and tours directing readers to experience, firsthand, the striking aftermath of the Ice Age floods.
The book includes: explanations of 19 types of landforms, guides to 65 flood-formed features, thirty-nine hiking and biking trails, and five driving tours and two aerial tours
A resident of Richland, Bjornstad is a licensed geologist/hydrogeologist who has studied the Ice Age floods since 1980. He is a senior research scientist at the Pacific Northwest National Laboratory.
