Mount Shasta and Surrounding Volcanic Peaks, California USA41.3N 122.3W
A series of volcanoes are visible in this orthorectified image, the most prominent of which is Mount Shasta, in the top left corner. Mount Shasta is a stratovolcano and the second-highest peak in the Cascade Range, at 14,179 feet (4,322 m).
The mountain consists of four overlapping volcanic cones which have built a complex shape, including the main summit. What remains of the oldest of Shasta’s four cones is exposed at Sargents Ridge on the south side of the mountain. Lava from the Sargents Ridge vent covers the Everitt Hill shield at Shasta’s southern foot.
The newest and highest cone is called the Hotlum Cone, named after the Hotlum glacier on its northern face; its longest lava flow, the 500 feet (150 m) thick Military Pass flow, extends 5.5 miles (8.9 km) down its northwest face.
One prominent cone, Shastina, is a 12,330-foot (3,760 m) high satellite cone. The fourth and final cone is exposed south of Shasta’s current summit and is called Misery Hill.
