An extinct, horseshoe-shaped, volcanic crater located on the east side of the upper Squamish River. Three cairns separated by a few hundred meters are located on the flat summit plateau; the easternmost cairn marks the highest point on the mountain although the others cairns are only slightly lower. The summit is not technically difficult from most directions although a few steep rock bands exist along the crater rim. It's mostly scree up to 30 degrees. See also "Little Ring Peak".
