Pre-emptor’s map Tête Jaune 3H 1919 [Raush (Raushuswap) River]
According to British Columbia Geographical Names, the original name was “Rivière au Shuswap,” abbreviated as “R. au Shuswap” on Trutch’s 1871 map of British Columbia [the text is compressed, and could easily be misinterpreted as RauShuswap.] Labelled “RauShuswap River” on Jorgensen’s 1895 map of B.C. Labelled “Raush (Raushuswap) River” on BC map 3H, 1914, 1915, 1919, and 1923, following the Geographic Board of Canada suggestion that Raush be adopted, being an abbreviation for Rivière AU SHuswap, in place of Raushuswap, in itself a corrupted abbreviation and too long a name for such a small river.
“The local name of the Big Shuswap conflicts with the Shuswap River further south and appears on recent government maps as Raushwap or Rausch River (from Riviere au Shuswap),” wrote Munday in 1925. The government maps that Munday mentions, using the spellings Raushwap and/or Rausch, are not identified.
The Raush Valley post office operated from 1915 to 1923; there are no known examples of the cancellation mark.
