<P> The U.S. section 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 . </P>
