North Cascades

The North Cascades are a section of the Cascade Range of western North America. They span the border between the Canadian province of British Columbia and the U.S. state of Washington and are officially named in Canada as the Cascade Mountains. They are predominantly non-volcanic, but include the stratovolcanoes Mount Baker, Glacier Peak and Coquihalla Mountain, which are part of the Cascade Volcanic Arc. The portion in Canada is known as the Canadian Cascades, a designation that also includes the mountains above the east bank of the Fraser Canyon as far north as the town of Lytton, at the confluence of the Thompson and Fraser Rivers.

The US portion of the North Cascades and the adjoining Skagit Range in British Columbia are most notable for their dramatic scenery and challenging mountaineering, both resulting from their steep, rugged topography. While most of the peaks are under 10,000 feet (3,000 m) in elevation, the low valleys provide great local relief, often over 6,000 feet (1,800 m). The summits of the rest of the Canadian Cascades are not glaciated in the same way and feature rock "horns" rising from plateau-like uplands, with the Manning Park and Cathedral Park areas known for their extensive alpine meadows, as is also the case with the eastern flank of the US portion of the range. Portions of the US side of the range are protected as part of North Cascades National Park.
