Among the western states, Idaho’s got one of the more interesting shapes, the result of decades of negotiations, schemes and the arcane doings of Congress in the 19th century, which are summarized nicely in an article in Idaho magazine, though it could use a few more maps. Not every is happy with the current Oregon-Idaho border, though I’m not holding my breath waiting for a change.

Idaho’s flag is less interesting; another state seal.

At least the seal has some Latin: Esto perpetua, let it be forever; it is forever. I assume that’s a wish for the existence of Idaho, or Idaho’s status as a state, not the seal or flag itself. New state flag designs for Idaho are kicking around on the likes of Reddit, but nothing official seems to be in the works yet. Pocatello has had a new flag since 2017, however, and it did need one.

We headed east from Boise on September 3. The easy way is on I-84. We drove to Mountain Home and then turned off on US 20, as previously mentioned. Go that way and you’ll eventually come to Craters of the Moon National Monument and Preserve. It’s a big blob on the map (753,000 acres) that has long intrigued me.

The monument was originally created in 1924 by President Coolidge partly due to the publicizing efforts of an interesting Idahoan, Bob Limbert, who explored the area, previously ignored as a wasteland, and wrote about it. President Clinton expanded Craters of the Moon greatly in 2000 and I’ve read that the Idaho legislature has asked Congress to make it a national park.

I’d be against it. Not that anyone has asked me, but it’s time to stop national park bloat. Sixty-three is more than enough. Sixty is fine, for that matter, a nice round number with ancient resonance. There’s nothing wrong with a place being a national monument. It’s an honorable old designation, the brainchild that most conservation-minded president, TR. I need to visit more of them myself: only 21 out of 134 so far, counting Craters of the Moon and Devils Tower.

The part of Craters of the Moon accessible to casual tourists is only a sliver, but quite a sliver. One trail leads over the aftermath of ancient lava flows, and a road leads to cones.

The terrain just cries out for a monochromatic treatment.

The day was warm enough to wear a hat and carry water, but not blazing hot. A scattering of other tourists were around, but nothing like the more popular trails of the national parks.

The place looks barren, but it isn’t so, since life adapts.

Except where it doesn’t. Yet.

We decided not to climb the enormous black cone, but if you look carefully, you can see a fellow who did. Note the trail on one of the smaller cones. That we did climb, reaching a view of the maw of the cone, though it has a grate blocking the way, to limit the erosive effect of a constant trickle of people clambering down.

More monochrome.

“The craters of Craters of the Moon… are definitely of volcanic origin,” explains the NPS paper guide, noting also that the name dates from long before anyone knew what the actual craters of the Moon looked like, at least up close. I don’t think any of the Apollo astronauts were reminded of Idaho. No matter, the name’s got some panache.

“But where is the volcano? These vast volumes of lava issued not from one volcano but from a series of deep fissures – known collectively as the Great Rift – that crosses the Snake River Plain. Beginning 15,000 years ago, lava welled up from the Great Rift to produce this vast ocean of rock. The most recent eruption occurred a mere 2,000 years ago, and geologists believe that future events are likely.”

Not to be confused with the Great Rift Valley, over in East Africa. The Digital Atlas of Idaho calls it the Great Rift system, “a series of north-northwest trending fractures… The total rift system is 62 miles long and may be the longest known rift zone in the conterminous United States.”

In other places, life has returned more robustly. There’s an easy trail through that as well.

A difficult place for trees, looks like.

We spent longer than planned at Craters of the Moon, which meant that we didn’t get to Victor, Idaho, our next destination, until well after dark. No big deal, it was worth it, and the nighttime winding road was a smaller version of the twisty drive near Sheridan, Wyo., so not bad either.
