Mammoth Mountain is a lava dome complex partially located in the town of Mammoth Lakes, California, in the Inyo National Forest of Madera and Mono counties. It is home to a large ski area primarily on the Mono County side.
Mammoth Mountain was formed in a series of eruptions that ended 57,000 years ago. Mammoth still produces hazardous volcanic gases that kill trees.
