There is a visitor center for the Grand Coulee dam. Sadly, as with a lot of similar things, it was closed while I was there due to the virus. While I couldn’t go in, I was rather taken with the structure itself. I’m not sure when it was built but it has a bit of a 70s space age feel about it. When in the park lower down the hill, it looks a little like a flying saucer has landed above you. I bet it looks interesting when lit up at night.
