 Cheam is the farthest northerly peak of a small group of peaks forming a local subrange, the Cheam Range, a small group of peaks forming a local subrange of the Skagit Range of the Canadian Cascades mountains (which are the Canadian extension of the North Cascades of Washington).It dominates the eastern Fraser Valley, rising above Bridal Falls and Agassiz just east of Chilliwack, British Columbia.It and three sister peaks form a group known as the Four Sisters or Four Brothers, which are part of the mountain wall framing the Lower Mainland; though visible from as far away as Vancouver Island on a clear day, like Cheam does for the Eastern Valley, they are a dominant part of the mountain skyline of Mission and the communities of Hatzic, Dewdney and Deroche.
