The Pacific Coast Ranges are a series of mountain ranges located along the western coast of North America. They extend from southern California to northern British Columbia, Canada. This region includes notable ranges such as the Sierra Nevada, the Coast Ranges, and the Cascade Range. The mountains are characterized by their rugged terrain, diverse ecosystems, and significant geological features. These ranges are shaped by tectonic activity, including the movement of the Pacific Plate and the North American Plate. The Pacific Coast Ranges are home to various climates, from Mediterranean in the south to temperate rainforests in the north. They also support a wide range of wildlife and plant species, making them an important area for conservation.
