I decide at the last moment not to go back to Yellowstone Park which our family spent a week exploring more than 30 years ago. I struck out instead from West Yellowstone, MT for Idaho Falls, then took in the Craters of the Moon National Monument and Preserves before landing in Idaho's capital Boise for the night. The drive through the lower comer of Montana into Idaho and the Gallatin and Targhee National Forests was another great scenic drive on the road to Idaho Falls where the town turned the Snake River into a power generating asset as well as creating a beautiful landscaped river front park. As I was driving through the sagebrush steppe called the Snake River Plain on my way to the Crater of the Moons National Monument & Preserve I got a call from Jack Lane who was on his return CRUIZ to Texas in his camper outside St. Louis and on his way to the Indianapolis Motor Speedway Museum. The other surprise on this long drive though sagebrush prairie were three giant Buttes rising out of the lava plain. A pit stop at the Big Lost River rest stop explained all the interesting and surprising geologic history of what I was seeing but wasn't understanding. The next stop was taking the 7 mile drive through the volcanic lava flows, a surreal landscape of over 1,000 square miles that U.S. Route 20 for runs alongside for more than 30 miles. After that, it was just get on to Boise, Idaho's state capital, and flop into a comfortable bed after this 377 mile CRUIZ. What was surprising to me though was that even 6 miles west of the capital, the landscape was still sagebrush prairie with no evidence of urban sprawl.
