The South Warner Wilderness is a federally designated wilderness area east of Alturas, California, USA. It encompasses more than of the Warner Mountains. It is within the Modoc National Forest and managed by the US Forest Service. Elevations range from to 9,895 feet〔 at Eagle Peak. The highest parts of the Warner Mountains were set aside in 1931 as a primitive area. In 1964, the Wilderness Act created the South Warner Wilderness. In 1984, were added to the wilderness with the passage of the California Wilderness Act.〔(California Wilderness Act 0f 1984 text, National Park Service website ) retrieved 3/5/2008〕 The Warner crest divides waters that flow west into the Sacramento/Pit River drainage, and east into the Great Basin Alkali lakes of Surprise Valley. Much of the crest is a narrow ridgeline with notable peaks such as Emerson Peak and Squaw Peak. The eastern side of the wilderness is a steep, abrupt escarpment of volcanic terrain of cliff bands and terraces. Very different from the east side are the western slopes. Heavily forested, steadily rising slopes furrowed by several drainages such as Mill Creek. The west side also includes a portion of a state game refuge. == Landscape == The Warner Mountain Range is a fault block range, with the Surprise Valley Fault on the east and the Likely Fault to the west. The steep escarpment on the east side of the range is the exposed side of the Surprise Valley fault.〔Hinds, Norman E. A. ''Evolution of the California Landscape'' Division of Mines Bulletin 158, 1960, p. 80〕 Geologists estimate that basalt lava flows occurred 15 to 30 million years ago, creating the Modoc Plateau which is a part of the larger Columbia Plateau. The breaking up of the crust occurred about 10 million years ago with large blocks moving and more volcanic lava flows, which created the mountains and block fault valleys of recent time.〔Alt, David D. and Hyndman,Donald W., ''Roadside Geology of Northern California'', Mountain Press Publishing, 1975, pp. 210-213〕 The landscape of today is not from mountain building but from the forces of erosion such as wind, water, and past glaciation. 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「South Warner Wilderness」の詳細全文を読む スポンサード リンク
