Dust storm, Wonder Valley, July 19, 2015

I was standing in my driveway looking south toward Highway 62 and the Pinto Mountains, a half mile away, when I saw a strip of dust come up.

At first I thought it was an off roader, but the cloud of dust kept getting bigger and denser.

This all happened very fast - in a matter of minutes.

Ken, watching the storm form.

It keeps getting bigger and coming closer. It's hard to even see the Pintos now.

 At this point we went in the house because we couldn't be sure how fast it was traveling. It seemed pretty fast. You can no longer see the Pinto mountains at all.

We came out a few minutes later and the dust storm had crossed Amboy. You can see the plume in the center is taller than the mountain.
