Fish & Wildlife manages this stretch of the Columbia River, various highlands and a lake here. Supposedly the area is good for wildlife, including elk and various birds. I thought the area looked desolate and didn’t see any wildlife. There are a couple dams upstream, and the river takes a long curve around to the right above. There used to be a paddling rental & shuttle business here, but they closed during Covid and haven’t reopened. I considered bringing my folding kayak for this relatively easy part of the Columbia to paddle, but I decided against it and didn’t see any other boats. It would have been very windy and difficult to get back.
In 1943 the US military took over this area, evacuating everyone. In the background above right there’s a building with a smokestack. That is Reactor B, which processed weapons grade plutonium for the Manhattan Project, and much of the land around here is still restricted. There used to be a small city of workers on the secret project, but only a few buildings remain and none were open for tours when I visited. The river was critical for keeping the reactor cool. Tours of the reactor are scheduled to resume in late 2027.
Behind the reactor are White Bluffs, which were formed by deposits in the Ice Age floods, along with patterns of river sediments called rhythmites. I did a bit of hiking around here, but there are still many restrictions on where you can go. In theory, the decades of isolation benefited wildlife, but USFWS allows hunting, fishing and motorized vehicles in much of the monument. Looking for wildlife is much more challenging near hunting zones, so I was disappointed but not surprised that I didn’t see any.
