I really love the clouds in this picture of the great sand dune!
This is the end of the gravel road in Sand Dunes National Park. There is a trailhead here, and also a campground. People were clearing out - the wind was making it rather unpleasant. We didn't spend much time in this park. We had other places to explore, so we headed on down the road. Stormy weather was threatening, so we dipped down into New Mexico, where the weather promised to be nicer.
