The Klamath Mountains are a rugged and lightly populated mountain range in northwestern California and southwestern Oregon in the western United States. They have a varied geology, with substantial areas of serpentinite and marble, and a climate characterized by moderately cold winters with very heavy snowfall and warm, very dry summers with limited rainfall, especially in the south.[2][3] As a consequence of the geology and soil types, the mountains harbor several endemic or near-endemic trees, forming one of the largest collections of conifers in the world. The mountains are also home to a diverse array of fish and animal species, including black bears, large cats, owls, eagles, and several species of Pacific salmon. Millions of acres in the mountains are managed by the United States Forest Service.[3][4] The northernmost and largest sub-range of the Klamath Mountains are the Siskiyou Mountains.[1]


Mount Ashland, the highest point of the Siskiyou Mountains

Physiographically, the Klamath Mountains include the Siskiyou Mountains, the Marble Mountains, the Scott Mountains, the Trinity Mountains, the Trinity Alps, the Salmon Mountains, and the northern Yolla-Bolly Mountains.[5] They are a section of the larger Pacific Border province, which in turn is part of the Pacific Mountain System (Pacific Coast Ranges) physiographic division.[6]

Protected areas

A large portion of the Klamath Mountains is managed by the United States Forest Service. Several national forests lie in the Klamath Mountains region, including the Shasta-Trinity National Forest, Siskiyou National Forest, Klamath National Forest, Six Rivers National Forest, and Mendocino National Forest.[7][8]

The Klamath Mountains contain 11 wilderness areas in both Oregon and California:[9][10]
