The mountain was the source of the 2010 Mount Meager landslide. On August 6, the southern peak of Meager collapsed in a series of major rockfalls. The rockfalls transformed into a large debris flow that dammed Meager Creek for about one day. The landslide dam was about high and impounded water in a temporary lake about 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 downstream and in the Lil'wat community at Mount Currie to evacuate the area.
