Well, yes. I'm not sure how a lake can be "dusty!" But that's what the map says. South fork of Potholes Coulee, Ancient Lakes wildlife area, Washington state. Looking southeasterly.

And one of the Ancient Lakes, in the wildlife area of the same name. Looking west out the coulee. Washington state, USA. The lakes are natural but their level has risen considerably since construction of the Columbia Basin irrigation project.

In the wildlife area of the same name, in Potholes Coulee, Washington state. The lake basins are natural but the water level has been raised considerably since the construction of the Columbia Basin irrigation project, on the plateau above, which has raised the water table. (Trees at a farmhouse in the irrigated area are visible on the skyline at the left.) So the area is not so remote as it appears! (And if you're wondering why the same area is a "plateau" and a "basin"--well, it's all in your perspective! ;)
