My dad sent these to me. They were taken by a friend of the family that still lives down in my hometown of Yuma, AZ. The pics were taken just south of the CA-Mexico border. The dust on the moutains is caused from the loose rocks rolling around. For those not familiar with desert mountains, the moutain sides are primarily loose rocks and boulders, not a lot of solid material on the surface.
