High Quality Content by WIKIPEDIA articles! The Rainbow Range, formerly known as the Rainbow Mountains, is a mountain range in British Columbia, Canada, located 40 kilometres (25 mi) northwest of Anahim Lake. Named Tsitsutl, which now is the name of its highest peak and meaning "rainbow mountains" in the Ulkatcho dialect of the Carrier language, is on the western edge of the Chilcotin Plateau, adjoining the Pacific Ranges of the Coast Mountains to the south, and the Kitimat Ranges of the Coast Mountains to the north. In some classification systems it is considered part of the Coast Mountains and has been assigned here in Wikipedia to the Pacific Ranges although it is not formally part of that range-complex.
