Monsoon from Sentinel Peak
When I stepped off the plane from Nepal in late June, it was about 110F (~40C) here in southern Arizona. Fortunately, the monsoon started soon after I arrived. After work one evening I drove up to the top of Sentinel Peak (near downtown Tucson) and shot a few panoramas of the lumbering monsoon storms as they approached from the south.
