The most dramatic cloud images usually result from unsettled weather conditions. It has been raining much of the day, and as we reached the point where the paved road ends near the tiny town of Arivaca, we stopped the car to marvel at the sight of storm clouds slowly lifting about twenty-five miles to the east over the Santa Rita Mountain range. I use a 400mm telephoto lens to move in on the clouds that hover around Mount Wrightson, the highest peak in the area.
