It wasn't until my second trip out to Death Valley that I made it out to Mesquite Sand Dunes. Truly a fantastic shooting experience. If you've got any water or weatherproofing gear use it! Blowing sand refreshes the landscape every day but will lodge in both gear and person in ways that will make your day uncomfortable. It should go without saying but it's hot and trudging up and down these dunes is more than a walk in the park.
