The South Cariboo historic roots go back to the fur trading days before the gold strike. By 1860, thousands of gold seekers thronged to the Cariboo to seek the precious metal. Between 1862 and 1870, over 100,000 people traveled the Cariboo Wagon Road from Lillooet, making their way north into Cariboo country.
Throughout this gold fever, certain roadhouses, because of their favourable locations along the Cariboo Wagon Road from Lillooet to Soda Creek, grew to be supply points for the gold seekers and the surrounding district. 100 Mile House, South Cariboo's dominant community, was originally one of these stopping points along the gold rush trail. 100 Mile House was so named because it was located 100 Miles from Lillooet (Mile 0) of the Cariboo Wagon Road. As the gold rush subsided, ranchers began to settle the surrounding area.
Today, the South Cariboo consists of a number of small unincorporated communities in the outlying area surrounding the District of 100 Mile House and has a population greater than 20,000.
Geographically, the South Cariboo is found in southcentral British Columbia nestled on the Fraser Plateau between the heights of the Coastal and Rocky mountain ranges. The Fraser River cuts through the middle of this rolling plateau dividing the Cariboo from the wilds of the Chilcotin. To the south is the lower, drier hills of the Thompson-Okanagan, and to the north is the central Cariboo, extending into the vast forests of Northern BC.
