All of the wilderness is in Northern California and is managed by the U.S. Forest Service. The wilderness spans three national forests: the Rogue River–Siskiyou, the Klamath, and the Six Rivers. The Siskiyou Mountains form one of the longest continuous crests in the Klamath Mountains region. Elevations range from to the summit of Preston Peak at above sea level. Trending in a north–south direction from the Oregon border down to near the town of Weitchpec and inland from the Pacific Ocean, the Siskiyous are dotted by rocky peaks rising over from the surrounding lowlands. == Flora and fauna == The Siskiyou Wilderness contains a diverse collection of conifer species including rarities such as Alaska cedar, Port Orford cedar, and the Klamath Mountains-endemic Brewer spruce.〔 〕 It is notable for the vast amounts of old-growth forests and many endemic species of wildflowers, shrubs and trees, as well as one of the world's largest concentrations of lilies. The wilderness is home to several rare species, including wolverine, martin, fisher, northern spotted owl and Roosevelt elk. There is also black bear, black-tailed deer, and many varieties of birds. The clear streams provide spawning grounds for steelhead, coho and Chinook salmon. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Siskiyou Wilderness」の詳細全文を読む スポンサード リンク
