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.
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.
