The Oregon Coast Range is a mountain range located along the coast of Oregon, stretching approximately 200 miles from the Columbia River in the north to the California border in the south. This range is characterized by its lush forests, diverse wildlife, and rugged terrain, making it a popular destination for outdoor activities such as hiking, camping, and birdwatching. The range is primarily composed of sedimentary and volcanic rock, shaped by millions of years of geological activity. It plays a crucial role in the region's climate, influencing rainfall patterns and providing vital watersheds for rivers like the Willamette River and Rogue River.
