Cascade Mountains, BC, are the north end of largely volcanic mountain ranges extending to California, 180-260 km east of the Pacific Ocean. There are no active volcanoes in BC like the US Cascades' Mount St Helens and others. The highest point is Lakeview Mountain (2628 m) in Cathedral Provincial Park. The BC Cascades show a transition from the wet coastal forest of the rugged Skagit Range to the drier interior vegetation of the Okanagan Range and of the ridge east of the Fraser River and south of LYTTON. Eastward they merge with the Thompson Plateau, an important mining district.
Granite quarries operate in the Hope area. Hwy 3 crosses the range via Allison Pass (elev 1352 m) between Hope and Princeton; the COQUIHALLA HIGHWAY between Hope and Merritt uses Coquihalla Pass (elev 1244 m). Popular outdoor recreation areas are at Cultus Lake, near Chilliwack, the Skagit Valley and Manning Provincial Park.
