Savage Mountain is an anticline extending from Bedford County, Pennsylvania southwest into Western Maryland.〔 Except when available at another wikiarticle or cited otherwise, Google Maps is the source for coordinates in this article: (Savage Mountain (MD) ), (Savage Mountain (PA) ), (Sand Patch Tunnel ), (Little Savage Mountain )〕 It is the western side of the Ridge-and-Valley Appalachians, and the eastern portion of the ridge forms the border of Garrett and Allegany Counties of Maryland. The anti-cline includes two component ridges in Maryland, Little Savage Mountain and Big Savage Mountain. Portions of Savage Mountain form the Eastern Continental Divide, separating watersheds draining to the Ohio River and those draining to the Potomac. To the northwest of Savage Mountain, waters drain to the Casselman River. The North Branch Potomac River watershed encompasses the southwestern and eastern portions of the ridge. ==History== After Nemacolin's Path and the first survey of the Potomac (1736-1737) had passed through the area, the Braddock Road over the ridge opened in 1757. By 1767, the Mason–Dixon line survey had placed milestones across the ridge〔(【引用サイトリンク】title=Maryland Inventory of Historic Properties: Allegany County )〕〔(【引用サイトリンク】title=Maryland Inventory of Historic Properties: Garrett County )〕 and the National Road was completed through the area by 1818. In 1911, construction began on the Borden and Big Savage Tunnels for the Connellsville subdivision of the Western Maryland Railway. In the 1930s, the Civilian Conservation Corps built a connection road that is now the 6.4 mile Monroe Run Trail.〔(【引用サイトリンク】title=New Germany, Casselman River Bridge & Big Run State Parks )〕 The Savage River Reservoir was constructed just southwest of the ridge in 1952 to provide a water supply for the Washington, D.C. area. On August 13, 1976, the freeway that would become Interstate 68 opened through the ridge. Due to severe fog conditions common along this stretch of highway, Maryland's first "fog warning system" was installed after a May 2003 crash that killed two and injured about 100 people.〔 〕 In 2001, the fire history and dendroecology of Savage Mountain oak stands were investigated. About 2,600 trees were later planted in the Savage Mountain Demonstration Plot #2 in 2007.〔(【引用サイトリンク】title=ARRI Arbor Day Events )〕 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「Savage Mountain」の詳細全文を読む スポンサード リンク
