Princeton is located in the Similkameen valley at the confluence of the Tulameen and Similkameen rivers in the foothills of the Cascade Mountains.
The rainshadow effect produced by this wall of mountains that stand sharply outlined on the western horizon makes for a dry climate. The Similkameen is one of the few east-west oriented valleys in British Columbia.
Topography and Terrain
Rolling dry grassland, which is ideal rangeland for cattle and horse ranching, rises from the valley to the forested highlands of the Thompson Plateau where myriad small lakes attract trout fishers and outdoor enthusiasts. Lower elevation forests are composed of aspen, ponderosa pine and Douglas fir, while Englemann spruce, lodgepole pine and sub-alpine fir thrive at higher elevations where heavy winter snowpacks provide additional moisture.

Ochre Bluff and Hoodoos
Mountainsides striped with ochre have been mined for thousands of years by the Similkameen First Nation, who used the red pigment to paint pictographs on rock walls around the region. The ochre was also a valuable trade good with other Aboriginal peoples. Ochre Bluff is located in a deep canyon where the Tulameen River has eroded the rock, exposing the ochre and also creating towering hoodoos.
Princeton Waterways
The Tulameen River flows in from the northwest and joins the east-west oriented Similkameen River in Princeton. Both rivers carry large deposits of gravel coming down from the mountains each spring, bearing gold and platinum. The Tulameen is one of only two rivers in the world known to carry the two metals together.
Gold Panning
Prospectors began panning these waterways in the 1800s, staking claims all along the shorelines. Some panners still find precious metals today.
Cascade Mountains
Clearly visible from hillsides around Princeton, the snow-covered, sawtooth peaks of the North Cascades present a variety of different ecosystems for outdoor enthusiasts to explore. Manning Provincial Park is the gateway to this natural resource.
