The Cascade Mountains run parallel to the Pacific Coast in the Pacific Northwest, extending through Washington, Oregon, and parts of Northern California.

The Cascade Range is a major mountain range in the western United States that runs roughly parallel to the Pacific Coast. Known for its volcanic peaks, such as Mount Rainier, Mount St. Helens, and Mount Hood, the Cascades are part of the Pacific Ring of Fire. While the Sierra Nevada Mountains also run close to the Pacific Coast, they are primarily located in California and run more inland. The Cascades are distinctive for their role in shaping the climate and geography of the Pacific Northwest.
