Mayon is a classic stratovolcano with a small central summit crater. The cone is considered the world's most perfectly formed volcano for its symmetry, which was formed through layers of lava flows and pyroclastic surges from past eruptions and erosion. The upper slopes of the basaltic-andesitic stratovolcano are steep, averaging 35â40 degrees.
Water partially fills a phreatic crater formed on the northern flank of Mammoth Mountain, the snow-covered peak in the background. This and other nearby craters were formed by explosive eruptions about 700 years ago that were distinct from nearby eruptions at the southern end of the Inyo Craters.eological Summary. Mammoth Mountain, a trachydacitic lava-dome complex, lies on the SW topographic rim of Long Valley caldera. The 3369-m-high volcano lies west of the structural rim of the caldera and is considered to represent a magmatic system distinct from Long Valley caldera and the Inyo Craters (Hildreth, 2004).
