Mount Shasta, whose last known eruption was in 1786, is the large stratovolcano featured in this north-looking, low-oblique photograph. Located in northern California in the southern Cascade Range, the glacier-crowned peak of Mount Shasta at 14 162 feet (4319 meters) is actually two volcanic mountains grown together to become one of the world’s largest volcanoes. Shastina, the smaller of the two peaks at more than 12 000 feet (3660 meters), is located northwest of Shasta, the larger peak, at the summit. Other features visible in the photograph near Mount Shasta are the Klamath Mountains to the west and northwest and the wide Shasta River Valley to the north.
