Mount Callaghan volcano

Mount Callaghan is a volcanic peak located east of the headwaters of the Squamish River, just northeast of the Powder Mountain Icefield and just south of the Pemberton Icefield in the Sea to Sky Country of southwestern British Columbia, Canada, about 20 km directly west of the Resort Municipality of Whistler. A crack was observed across Callaghan's summit in the spring of 1999. In 2000, a section of the summit collapsed.^[2] Callaghan Lake lies below the south face of the mountain.
