Capricorn Mountain is one of the several volcanic peaks of the Mount Meager massif in southwestern British Columbia, Canada. The slopes of Capricorn Mountain appear to be more gentle than other volcanic peaks of the massif. The mountain consists of a boomerang-shaped ridge, with one summit on each end of the boomerang and the main summit in the centre.
On August 6, 2010, a large debris flow started in the vicinity of the Capricorn Mountain. The dam created by the debris flow, on Meager Creek, lasted about one day and was about 30 m (98 ft) high, and impounded water in a temporary lake about 4 km (2.5 mi) long. The debris flow also crossed the Lillooet River downstream and wiped out a forestry road on the opposite bank of the Lillooet River. The response of emergency personnel, fearing a sudden failure of the dam on Meager Creek, was to direct residents on the Lillooet River floodplain, in the village of Pemberton 55 km (34 mi) downstream and in the Lil'wat community at Mount Currie to evacuate the area.
