The American River (''Río de los Americanos'' during the Mexican-ruled period before 1846) is a California river which runs from the crest of the Sierra Nevada mountain range to its confluence with the Sacramento River in Sacramento, California. The Sacramento River continues to eventually empty into the San Francisco Bay and the Pacific Ocean at San Francisco, California. The American River flows entirely within California. ==Course== The American River is divided into the North, Middle, and South forks, which are located in El Dorado County, Placer County, and Sacramento County. The river's three forks originate in the Tahoe and Eldorado National Forests. The American River's section of the Sierra Crest extends ~ between the north triple watershed point (South Yuba, North Fork American, and Truckee rivers) at Mount Lincoln () to the Winnemucca Lake triple point (Sacramento, San Joaquin, and central Lahontan hydrologic subregions). From the confluence at Auburn, the combined North and Middle Forks river flows at an elevation of in a forested canyon deep and is called the North Fork. It meanders through additional canyons past the site of the abandoned Auburn Dam to where it meets the South Fork at Folsom Lake. All three forks are known for their verdant canyons, forested ridges, massive rock formations, trails, backcountry winter adventuring among snowy peaks, fishing and white water rafting. Below Folsom Lake, the river passes through an urbanized area but is buffered by a riparian park, the American River Parkway. Containing fishing and family-oriented rafting, and paved bicycling and multi-use trails, it runs 〔 from Folsom Lake to the river's confluence with the Sacramento River. The American River Parkway incorporates Historic Leidesdorff Ranch, a cattle and wheat agribusiness owned by the "African Founding Father of California." Jedediah Smith Memorial Trail, a meandering, uninterrupted cycle path, hugs the river bank from Old Sacramento to Folsom Lake. 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「American River」の詳細全文を読む スポンサード リンク
