The entire length of the river is protected National Wild and Scenic River, the only such river in the contiguous 48 states of the United States.〔(BLM Oregon: Wildwood Recreation Site - html version )〕 Several portions are in protected wilderness. It is affluent to the Sandy River. ==Course== The overall course is sickle-shaped with the point facing north at Mount Hood and the handle facing west. The headwaters are on the Mount Hood's south face at the foot of Palmer Glacier east of Silcox Hut. The canyon is visible most of the year—when not snowfilled—where it crosses the Pacific Crest Trail at . The river continues directly southward for a few miles and remains east of Timberline Road. As it descends below , it turns southwest, and continues under Oregon Route 35, elevation , just east of the junction with U.S. Route 26, and crosses under Route 26 as well. The West Fork begins in the Timberline Lodge ski area under the Pucci chairlift. It flows south-southwest and is joined by natural cold springs at the level, continues south-southwest and crosses under Highway 26 just west of the Highway 35 junction. Just after they cross Highway 26, the West Fork and Salmon River join, and a half mile (1 km) later, the Salmon is joined by the East Fork Salmon River which comes out of a steep valley just north of, and below, Barlow Pass. The combined river flows directly south through Red Top Meadow for about and begins meandering slightly through Salmon River Meadows, elevation . At the south end, the river is joined by Ghost Creek and turns west-southwest for about before meeting Mud Creek, which flows from Trillium Lake. About downstream from Mud Creek, it enters the eastern boundary of Salmon–Huckleberry Wilderness A steep east–west gorge captures the Salmon River and collects several creeks—Inch, Draw String, Linney—which join it from the south. It turns northwest, flows over a series of waterfalls ranging from high: Stein Falls and Split Falls, and turns directly north to go 90 degrees counter clockwise around a volcanic prominence. South of the Salmon River, Iron Creek merges with Tumbling Creek and flows over Hideaway Falls a quarter mile south of the junction between Tumbling, Swift, and Kinzel Creeks and the Salmon River, at elevation . Just after joining with Goat Creek it turns northwest and flows over three closely spaced falls: Vanishing Falls, Frustration (60 ft), and Final Falls, which are at the foot of cliffs to the south. A half mile later, Copper Creek joins from the south and, a mile later, Bighorn Creek joins from the south and the river leaves the wilderness area. About later, the South Fork Salmon River—which drains about of rugged mountains northeast of Squaw Mountain—joins a mile above Green Canyon Campground, and enters the last on a comparatively level grade with occasional short rapids. It meanders through several areas with houses near Welches and Wemme, then goes through Wildwood Recreation Site which provides educational and recreational experiences. It crosses (again) under Highway 26 and merges with the Sandy River near the community of Brightwood. 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「Salmon River (Clackamas County, Oregon)」の詳細全文を読む スポンサード リンク
