Geology Of New Hampshire
The geology of New Hampshire is similar to that of the rest of New England in comprising a series of metamorphosed sedimentary and volcanic rocks of Late Proterozoic to Devonian age, intruded by many plutons and dikes ranging in age from Late Proterozoic to early Cretaceous. New Hampshire is known as "the Granite State", but less than half is underlain by granite; much of it is schist or gneiss, both of which are metamorphic rocks. Geological structure The state straddles three composite tectonostratigraphic terranes. The larger part of the state lies on the Central Maine composite terrane, comprising the Central Maine trough in the east and the Bronson Hill mantled gneiss domes in the west. A small area of the first composite terrane belongs to the Hurricane Mountain belt and olistostrome belt. The northernmost corner of the state lies in the Connecticut Valley trough of the Boundary Mountains composite terrane. In the coastal region in the southeast is the Merrimack–Orringt ...

Terrane
In geology, a terrane (; in full, a tectonostratigraphic terrane) is a crust fragment formed on a tectonic plate (or broken off from it) and accreted or " sutured" to crust lying on another plate. The crustal block or fragment preserves its own distinctive geologic history, which is different from that of the surrounding areas—hence the term "exotic" terrane. The suture zone between a terrane and the crust it attaches to is usually identifiable as a fault. A sedimentary deposit that buries the contact of the terrane with adjacent rock is called an overlap formation. An igneous intrusion that has intruded and obscured the contact of a terrane with adjacent rock is called a stitching pluton. Older usage of ''terrane'' simply described a series of related rock formations or an area having a preponderance of a particular rock or rock groups. Overview A tectonostratigraphic terrane is not necessarily an independent microplate in origin, since it may not contain the full thickness ...

Old Man Of The Mountain
The Old Man of the Mountain, also called the Great Stone Face and the Profile, was a series of five granite cliff ledges on Cannon Mountain in Franconia, New Hampshire, United States, that appeared to be the jagged profile of a human face when viewed from the north. The rock formation, above Profile Lake, was tall and wide. The Old Man of the Mountain is called "Stone Face" by the Abenaki and is a symbol within their culture. It is also a symbol to the Mohawk people. The first written mention of the Old Man was in 1805. It became a landmark and a cultural icon for the state of New Hampshire. It collapsed on May 3, 2003.New Hampshire Division of Parks and Recreation: Old Man of the Mountain Historic Site

Monadnock Region
The Monadnock Region is a region in southwestern New Hampshire. It is named after Mount Monadnock, a 3,165 foot isolated mountain, which is the dominant geographic landmark in the region. Although it has no specific borders, the Monadnock Region is generally thought of comprising all of Cheshire County and the western portion of Hillsborough County. In addition to the frequently hiked Mount Monadnock, the region offers abundant opportunities for outdoor recreation, including four New Hampshire state parks. Pisgah State Park consists of of forest, seven protected ponds popular for fishing, and six trails that may be used for hiking, mountain biking, ATVs, and snowmobiles. The Monadnock Region also boasts four recreational rail trails, lakes with public swimming beaches, and three ski areas. The largest municipality, and only city, in the region is Keene with 23,409 residents. The nearby town of Peterborough is famous for the MacDowell Colony and for being the setting of the Th ...
