Sumas Mountain (British Columbia)

Sumas Mountain, aka referred to as Canadian Sumas to distinguish it from an identically-named mountain just south in Washington state, is a relatively large mountain rising from the floodplain of the Fraser River in the Lower Mainland of southwestern British Columbia, Canada. Its western end is in the urban area of Abbotsford and is home to a number of suburban areas of that city, notably Clayburn. Its higher eastern reaches tower over Greendale, a community within the City of Chilliwack and is mostly wilderness; the mountain's summit, Sumas Peak, is located in this area, along with Chadsey Lake. The mountain is separated from the Cascade Mountains by the drained lake now called Sumas Prairie, south of which is its American sister, Sumas Mountain, and which is part of the greater floodplain of the Fraser River (the Fraser Lowland). West of the mountain is Matsqui Prairie, another floodplain, and north of the Fraser, which lies along hte mountain's north flank, are similar floodplains - Nicomen Island and Hatzic Prairie.

Sumas Mountain Provincial Park is located in the higher, northern reaches of the mountain. Some mining has taken place in the mountain, notably brick-clay, which gave rise to the mining community of Clayburn. Located on the mountain's north foot, adjacent to the Fraser, is a Canadian Forces base naval station. On its south side is the reserve of the Sumas First Nation.

Name

"Sumas" is a Halqemeylem word meaning "a big level opening", referring to the Sumas Prairie area south of the mountain, formerly Sumas Lake. A common 19th Century spelling of Sumas was "Smess"; Simon Fraser's journal recorded the name as "shemotch".
