Good morning, my friends. It was a beautiful drive from Electric City to Quincy, Washington, yesterday. So much of the way, we were driving alongside Banks Lake. We’d driven through the little town to the state highway. As we passed through this canyon, we could see the lake on the other side.
Grand Coulee is a large geological feature, approximately 50 miles (81 kilometers) long and averages about 1 mile (6 kilometers) in width. It is designated a “National Natural Landmark.” Within the coulee there are illustrations of a series of geological events beginning with a low range of granite mountains through which the ancestral Columbia River flowed. Outpourings of lava built up the Columbia Plateau, diverting the course of the river. That was followed by deformation of the lava beds, advance and recession of glacial ice, the cutting of a new river course, the formation and retreat of waterfalls, and the return of the Columbia River to its present channel, leaving the Coulee high and dry until humans turned part of it into a huge reservoir by artificial damming.
In this next image, we were crossing the "dry dam" portion of the Columbia Basin Project. Banks Lake (mentioned above) covers nearly 27,000 acres within the northern portion of the Grand Coulee and was formed by building dams at both ends of the coulee channel. At the other end from here is the Grand Coulee Dam. To create a reservoir, dams are required at both ends. The reservoir is filled by pumping water uphill from Lake Roosevelt behind the Grand Coulee Dam to supply irrigation and power generation. The lake is named after Frank A. Banks, the construction supervisor for the Grand Coulee Dam.
I thought it might help to show this to you on a map. The red pin marks where Grand Coulee Dam is. The large circled area shows the extent of Banks Lake. The smaller circle in the lower left is where we are now.
Today’s hike is a loop, approximately 4 miles, and so you’ll want your most comfortable hiking boots. I recommend a good breakfast too. That’s what’s up next here. Scrambled eggs are sounding good. The weather is looking sunny, and I’ve read there’s not much shade on the trail. Hats are recommended.

So much interesting scenery. Your camp site is lovely. Hope the hike was enjoyable. I envy you the fall color. The heat index here was over 100 F yesterday. I'm not sure autumn is going to visit us this year.
I'd have been tempted to stop at Red Silo for coffee!
Hi Barb....you have some lovely photos there...nice to see that youre still here too
