SE Idaho/Craters of the Moon
In Idaho, most of the historical markers aren't about what people have done there. They are about geologic events millions of years ago. The following are photos near highway 33 in SE Idaho, near Howe and Arco. The Centennial Mountains run along the north-south border of Montana/Idaho, and the plains at their feet are a mix of volcanic spew, sagebrush, and irrigated farms. Further to the west, by Craters of the Moon, it gives way to pure volcanic rock, remnants of a (very recent! only 2000 years old) volcanic rift zone. In spring it is beautiful and lonely; in winter it's very isolated and snowy.
