Cauldron Dome is a volcanic mountain in British Columbia, Canada, within the Mount Cayley volcanic field. It is a tuya, a flat-topped, steep-sided volcano formed by lava erupting beneath ice, and part of the Garibaldi Volcanic Belt within the Canadian Cascade Arc. The mountain is made of coarsely plagioclase-orthopyroxene-phyric andesite lava flows. Its most recent eruption occurred in the Holocene, placing it within the relatively young volcanic history of southwestern British Columbia. Cauldron Dome is one feature in a larger volcanic landscape shaped by both eruptions and glaciation.
