Skagit Range
The Skagit Range is a subrange of the Cascade Range in southwestern British Columbia, Canada and northwestern Washington, United States, which are known in Canada as the Canadian Cascades or, officially, the Cascade Mountains. The Skagit Range lies to the west of the Skagit River and east and north of the Chilliwack River and flanks the Upper Fraser Valley region of British Columbia's Lower Mainland.
Of the three subranges of the Canadian Cascades—the Skagit, Hozameen, and Okanagan ranges—the Skagit is the most mountainous. It continues north to the Fraser River, sometimes using different local names. The Hope Mountains, and the "Anderson River Group" are separated from the main Skagit Range by distinct natural boundaries, but are otherwise similar in character.
Geography
According to Fred Beckey there are differences of opinion about the names and locations of the subranges of the northern Cascades, especially between Canadian and American geographers. Nervertheless early geologists and topographers had a fundamental agreement about the location and names of the subranges. The Skagit Range was seen as the mountainous area from the Skagit River northwest to the Fraser River. More recent Canadian maps show the Skagit Range as bounded to the west by the Sumallo-Nicolum valley and extending north along the east side of the Coquihalla River.
