Red Cones
Overview
The Red Cones are twin volcanic cinder cones south of Mammoth Mountain and among the most recent eruptive events along the Mono-Inyo volcanic chain. Formed roughly 8,000 to 9,500 years ago, gas-rich basaltic magma erupted explosively through north-south fractures in the Earth's crust, sending glowing fragments skyward that cooled midair and accumulated into two steep-sided cones. Their vivid red and rust-brown coloration comes from iron in the volcanic rock oxidizing as it cooled and weathered. Rising above dense Jeffrey pine forest, they stand as a striking reminder that the landscapes around Mammoth Lakes sit atop a still-active volcanic field.
