I've been wanting to see the Kelso Dunes in the Mojave National Preserve for a long time and last weekend I finally made it out there. I was not disappointed. I arrived late in the afternoon as it started to cool down and made the 1 and 1/2 mile ascent to the top. I only ran into 5 other people on the dunes. The Mojave National Preserve is the least visited National Park in the United States. Fine by me.
