(These pictures are from Wednesday). We made a stop at Lake Lenore on Wednesday. Lake Lenore is a long, narrow lake (8 mi long, 15ft deep) formed by the Missoula Floods in the lower Coulee just north of the town of Soap Lake. There is a trail that leads up to caves in the basalt rock.
Driving further up north on Highway 17 brings one to Dry Falls, named for the massive waterfalls that existed there during the Pleistocene Epoch, when ice sheets and glaciers covered huge parts of Earth’s surface. This area was at the southern end of the Cordilleran ice sheet, and the melting of the glaciers carved out the coulees in the basalt rock that we see today.
