San Francisco Mountains, Arizona, USA April 1998 The San Francisco Mountains (volcanic field), including snow capped Humphrey’s Peak (12,633 feet—3851 meters) the highest point in Arizona, is visible near the center of the picture. The city of Flagstaff (not distinctive in this wide view) is located immediately south of Humphrey’s Peak. The lighter colored, oval shaped feature southeast of Humphrey’s Peak is Mormon Lake. Southeast of Mormon Lake, part of the Mogollon Plateau can be seen as it extends in a general east-west direction. Northeast of Humphrey's Peak a section of the Painted Desert of north central Arizona is visible. The intermittently flowing Little Colorado River and its deeply incised stream channel can be traced across this arid environment as it heads northwest, eventually entering the Colorado River at the eastern end of the Grand Canyon (northern or lower right corner of the image)
