Ice Age Floods National Geographic Trail

5/27/2010 Lewis and Clark National Historic Trail.

5/28/2010 Lake Roosevelt National Recreation Area. Joined the Columbia and in Coulee Dam (the town) stopped at Grand Coulee Dam [on the Ice Age Floods NGT]. Now, a channel carved by the racing waters is called a coulee, and the huge one carved by the flood is the Grand Coulee. [Grand Coulee NNL - an ancient river bed stretching for about 60 miles, created by volcanic activity and land periodically uplifting and subsiding] At the very impressive, very large dam, stopped at the interpretive center and saw a good film about the flood, and some exhibits. Sun Lakes Dry Falls State Park.

9/20/2024 Multnomah Falls ... Crown Point State Scenic Corridor

9/21/2024 ... drove south to West Linn for a large pull-out on the NW side of the river. This site, on the Ice Age Floods National Geologic Trail, is for a view of Willamette Falls. These falls are the second largest, by volume, waterfall in the U.S., created as a receding waterfall during the outflow of the Ice Age Floods. The 42-foot-high and 1,500-foot-wide falls occurs 26 river miles upstream from the Willamette's confluence with the Columbia River. The view wasn’t that spectacular here, being a little high and far away. We circled around across the river into Oregon City and stopped at another roadside pullout for a view of the falls in the other direction. This view was much closer, and we could see the power generation and industrial infrastructure amazingly integrated into the falls.
