 The route then went west from there down the Thompson River either to the lower gold-bearing bars of the Fraser River between what is now Lytton, British Columbia and Yale, British Columbia, or via Hat Creek and Marble Canyon to the upper Fraser goldfields around present-day Lillooet, British Columbia.A shorter branch-route to the lower Thompson and lower Fraser Canyon diverged from the main route at the confluence of the Similkameen River and the Okanogan (at present-day Oroville, Washington).Cayoosh and The Fountains are today's Lillooet, British Columbia and environs.
