The Thompson Country, also referred to as The Thompson and in some ways as the Thompson Valley and historically known as the Couteau Country or Couteau District, is a historic geographic region of the Southern Interior of British Columbia, more or less defined by the basin of the Thompson River, a tributary of the Fraser and focused on the city ofKamloops.
The Thompson Country is semi-arid and desert-like, except in the upper reaches of the North Thompson and in the higher areas of the plateaus to the north and south of the river. Because of the low elevation of the valley's floor, winter temperatures are not too severe, and with the region in the immediate rainshadow or the Coast Mountains and Cascade Range, summer temperatures are among the hottest in Canada. The main image of the region is sagebrush and rangeland, with benchlands flanking the Thompson's deepening canyon from Savona downstream, and desert and, higher up, pine-covered mountains and hillsides flanking the river and Kamloops Lake, which lies at the heart of the region. Lytton vies with nearby Lillooet for the title of "Canada's Hot Spot", with summer temperatures regularly above. Ranching is the historic core of the economy in the South Thompson and the adjoining Nicola and Bonaparte Countries, and also northeast of Kamloops in the Shuswap Highland country towards Adams Lake and the rest of the Shuswap Country. Logging and tourism are other traditionally-important industries, especially in the North Thompson.
History
Most of the Thompson Country is the territory of the Secwepemc people. From Spences Bridge downstream the Thompson as well as the Nicola is the territory of the various Nlaka'pamux nations. The Thompson Country, the South Thompson in particular, was one of the first areas of the Colony of British Columbia which were opened up to land alienation and active settlement. Originally traversed by fur traders using what was known as the Brigade Trail, which ran from the Okanagan via Kamloops northwestward to Green Lake, by the last leg of the Okanagan Trail from Washington Territory to the Fraser Canyon, and its western extremity was the key section of the Cariboo Road connecting the Fraser Canyon to the Cariboo Plateau and its distant goldfields, it has been the scene of many important episodes in the history of British Columbia. Many of the earliest ranches in the Interior remain today, with the Douglas Lake Ranch, based in the Nicola Country but spanning the Thompson and including some of the Shuswap, one of the world's largest. Near Cache Creek, the historic Ashcroft Manor and Semlin Ranch and others were British military land-grants, the Ashcroft and Semlin Ranches home respectively to a Lieutenant-Governor and a Premier. The Thompson's settlement and history and economy have been dominated by the presence of both transcontinental rail lines flanking the Thompson, with the Canadian National Railway coming down the North Thompson, the Canadian Pacific Railway along the South Thompson.
