:''This article is about the mountain in New Hampshire. For other mountains with similar names, see Monadnock (disambiguation)'' Mount Monadnock, or Grand Monadnock, is a mountain in the New England state of New Hampshire, known for its presence in the writings of Ralph Waldo Emerson and Henry David Thoreau. It is the most prominent mountain peak in southern New Hampshire and is the highest point in Cheshire County, New Hampshire. It has long been known as one of the most frequently climbed mountains in the world.〔(NH Division of Parks & Recreation: Monadnock State Park )〕 At , Mount Monadnock is nearly higher than any other mountain peak within and rises above the surrounding landscape. Mount Monadnock, northwest of Boston and southwest of Concord, is located within the towns of Jaffrey and Dublin, New Hampshire.〔 The term "monadnock" has come to be used by American geologists to describe any isolated mountain formed from the exposure of a harder rock as a result of the erosion of a softer rock that once surrounded it (a landform termed ''inselberg'' elsewhere in the world). Monadnock's bare, isolated, and rocky summit provides expansive views. A number of hiking trails ascend the mountain, including the Metacomet-Monadnock Trail and the Monadnock-Sunapee Greenway.〔DeLorme Topo USA 6.0. (2006). Mapping software. Yarmouth, Maine:DeLorme.〕 It remains clear largely because of fires set by early settlers. The first major fire, set in 1800 to clear the lower slopes for pasture, swept through the stands of virgin red spruce on the summit and flanks of the mountain. Between 1810 and 1820, local farmers, who believed that wolves were denning in the blowdowns, set fire to the mountain again. The conflagration raged for weeks, destroying the topsoil and denuding the mountain above .〔 ==Name== The word "monadnock" is an Abenaki-derived word used to describe a mountain. Loosely translated it means "mountain that stands alone",〔("Devonian Period." ) New Hampshire Geology Home Page. Web. 23 Jan. 2011.〕 although the exact meaning of the word (what ''kind'' of mountain) is uncertain. The term was adopted by early settlers of southern New Hampshire and later by American geologists as an alternative term for an inselberg or isolated mountain. Mount Monadnock is often called ''Grand Monadnock'', to differentiate it from other Vermont and New Hampshire peaks with "Monadnock" in their names.〔Baldwin, Henry I. (1989). ''Monadnock Guide'' 4th edition. Concord, New Hampshire: Society for the Protection of New Hampshire Forests.〕 Its official name on federal maps is "Monadnock Mountain".〔(http://geonames.usgs.gov/apex/f?p=gnispq:3:::NO::P3_FID:868516)〕 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「Mount Monadnock」の詳細全文を読む スポンサード リンク
