From Ennis we drove out of the lush Madison Valley and into the quite different landscape of the Idaho high desert to Arco. This area has two claims to fame, one natural and one very definitely manmade. The natural one is the surreal and starkly beautiful landscape that makes up the Craters of the Moon National Monument. Summer had finally arrived in full force which limited the time we were comfortable wandering around this crazy landscape but we returned several times in order to fully appreciate the forces that created this harsh environment. It really is other-worldly. Lava tubes, cinder cones, spatter cones; we learned about and saw them all. We walked/crawled through a lava tube “cave” and climbed to the top of a huge cinder cone. This place is unlike any other we’ve been to. Well worth the trip (and a strong NASA connection, too).

The second claim to fame in the area is atomic power. The large, and frankly mysterious, Idaho National Lab is just down the road. While it’s not exactly in the middle of nowhere, you can see it from there. Among other things, this is where the world’s first breeder reactor was brought on-line. Arco, Idaho is the first town to be totally powered by atomic energy. And this is where the technology, processes, and procedures were created to power the Navy’s submarines with nuclear reactors, thus explaining the conning tower rising out of the ground as you enter town. It’s more than a little strange.

We took some nice drives, toured the Experimental Breeder Reactor 1 (EHB-1), ate some good ribs and smoked baked potatoes, and generally enjoyed our time in Arco. Especially when Patti was able to enjoy horses right outside our window. Simple pleasures.
