Haboob in Death Valley

While in Death Valley earlier in February, I looked out the window to see a huge wall of dust and sand (and likely some salt) approaching. I quickly grabbed my camera and began shooting. We got in the car and "followed" (in front)it down the valley for at least 10 miles, stopping to take photos until it caught up to us. We estimated it to be 2-3000 ft high and traveling at about 30-35 mph. It appeared to extend all across the valley to the Panamints (which are 30 mi away).

This photo was taken from the deck at Badwater. I took many different perspectives from close to far and enjoyed every minute:)
