Between 15,000 and 2,000 years ago, the Craters of the Moon Lava fields formed during eight major eruptive periods and grew to almost 620 square miles. The region experiences basin and range faulting, which stretches or pulls apart the crust. The Lost River Range north of the town of Arco provides good evidence that these forces are still active. In 1983 there was a magnitude 6.9 earthquake, during which Mount Borah rose about 1 foot and the Lost River Valley in that vicinity dropped about 8 feet. And we think things rock and roll around the San Francisco Bay Area!
There are cinder cones and lava fields all round us; wild flowers, lichens and a few tenacious trees bring spring color to the immense sea of black in the high desert sagebrush. After a bite to eat, we check out the visitors center and some of the local history, but we have another 4 hours to reach our destination, so we're soon back on the road. Next time we're here we'll plan on some hiking. Had to have this postcard to frame. The creator is author Ilan Shamir.
Tomorrow we're headed to Yellowstone and the Tetons for a day trip in the Honda. In spite of our expensive learning curve, we're glad we brought it along. We have much more flexibility to explore now.
