The Pacific Northwest Mountains include the Cascade and Klamath Mountains.
The Cascades stretch from the Southern British Columbia through Central Washington and Oregon and includes a separate area in Northern California.They have a mild to severe climate, varying by elevation, with mostly dry, warm summers and relatively mild to cool, very wet winters. Large areas are in public lands and there is little agriculture in this region. Larger towns include Stevenson, Cascade Locks, and Oakridge.
The Klamath Mountains are between the Cascades and the Coast Range in Southwestern Oregon and Northwestern California. Winters are moderately cold with very heavy snowfall and summers are warm and very dry, especially in the south. There is some farming in the valleys. Larger cities and towns include Roseburg, Grants Pass, Medford, Ashland, Yreka, and Weaverville.
