|Located 4 km south of Lightning Lake. Frosty Mountain is the highest summit in Manning Provincial Park. The peak has two summits: the lower east summit (2410m/7900') and less than 1 km away, a higher west summit (7950' on map). On the 1:50K map, the point labelled "Frosty Mountain" is 7900', but 1 km to the northwest is a higher peak labelled 7950'. For purposes of this encyclopedia, we designate the highest point to be the "true" Mount Frosty, and the east peak to be a sub summit.|
From the east summit, a loose and steep climb leads to the higher west summit about 60 minutes further on. The entire mountain consists of vertical, thrust-up metasedimentary rock from the ancient Methow Ocean. The main summit ridge offers a striking view of this region-wide rock formation, juxtaposing perfectly vertical beds with its jagged, kilometer-long ridgeline. The rock produces fine piles of rubble.
The east peak is badly windblown so skiing off the summit ridge is hazardous to skis and skier.
