Ring Mountain, also called Crucible Dome, is a tuya in the Mount Cayley volcanic field, British Columbia, Canada. It has a horseshoe shaped crater, located on the east side of the upper Squamish River. Outcrops on Ring Mountain's western side contain highly variable, fine-scale jointing and are locally broken down into many small spires and knobs. The age of Ring Mountain is unknown, but probably formed during the Fraser Glaciation like most tuyas in Canada.
