I'm looking out the window from our hotel room, 10th floor, at the mountains. Directly ahead of me, in the hills, I can see the streaky tendrils of distant rain, in four distinct bands. Just to the left is a taller mountain that just for a minute was haloed by all the light from a break in the clouds.
Now, maybe two minutes later, there is a wide streak of rainbow straight down onto the taller mountain. The arch vanishes into the clouds.
I love the high desert. It's the most beautiful scenery in the world.
