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.
