As hoped with the adjusted schedule from yesterday, I was able to get rolling just after 7 this morning which got me to Craters of the Moon National Monument just after 9 in the morning which was at least two hours earlier than if I had camped in Mountain home as planned.
Craters of the Moon is an area of the Snake River Rift valley. This region was formed as the continental crust drifted over a hot spot in the mantle. Yellowstone is currently over this hot spot, hence all of the geological and geothermal activity there.
The entire region is covered with cinder cone volcanoes of various ages and sizes and lava, lots of lava. Everywhere you look there is lava of one sort or another. There are even lava tubes that have opened up and are now caves. A few of which you can get into and explore. I just went through the biggest (and quickest) as I didn’t want to spend the whole day here – though I easily could have. All in all it’s a pretty interesting place.
As this was really just a travel day and CotM happened to be along the way I wanted to stop. But after three hours it was noon and I had seen most of the highlights of the park, so it was time to roll again.
I got back on the road headed for West Yellowstone and my campground, but after only about 45 minutes I came across a sign advertising EBR-1 Historic site and since I had just entered an area designated as the Idaho National Laboratory, I was intrigued. I followed the sign down the road, only a mile out of my way, and found myself at EBR-1. That’s Experimental Breeder Reactor #1, the world’s first nuclear power reactor.
It first went online in 1951 and was decommisisoned in ’64 and is now a national historic site and you can tour the place. So I did. Pretty interesting stuff. The best factoid is that the word scram – as in to shut something (a nuclear reactor for instance) OFF quickly is an acronym. Seems the Manhatten project reactor had a sophisticated emergency system – a guy with an axe would cut a rope which would release a control rod into the nulear pile. Hence; Safety Control Rod Axe Man – or SCRAM.
I’m always amazed at what sort of things our government and military were willing to consider during the Cold War – especially the early years. Turns out there was serious investigation into developing nuclear powered…
wait for it…
They actually went so far as to build actual test engines. The idea never went too far, they realized advancements in conventional jet engines were surpassing their experiment. Not to mention the safety concerns about nuclear reactors flying around and possibly crashing or being shot down. Of course they did crash one or blow it up or something to prove that it would be safe. I feel safe, don’t you?
After about an hour there, I saw all there was to see and headed off for some lunch and the rest of my day’s drive. I made to West Yellowstone and one of the nicest KOA campgrounds yet. It would be perfect if the WiFi worked at my actual campsite, but that’s the only complaint. Not too bad since I’m supposed to be camping!
