great pictures, but never figured Idaho would have a dessert. Love waterfalls also. One summer we planned our camping (in Michigan) to find as many waterfalls as we could squeeze in in 10 days...that was 40 years ago and a few we had to hike back to find...those falls in your picture are great..couldn’t figure out at first if it was water or snow....
I explored the ice caves at remote Craters of the Moon with my dad when when I was 12 years old....I will never forget it.
