Belknap Mountain
Belknap Mountain is a mountain located in Belknap County, New Hampshire, United States, south of Lake Winnipesaukee. Like the county, the mountain and the associated surrounding Belknap Mountains are named after Jeremy Belknap (1744–1798), a renowned preacher, historian, and author of ''The History of New Hampshire''. The mountain is within Belknap Mountain State Forest. The peak of Belknap Mountain is the highest point in the county. Although of only modest elevation, the isolation of the Belknap Mountains gives Belknap Mountain of relative height above the low ground separating it from the White Mountains, making it one of the fifty most topographically prominent peaks in New England. Belknap Mountain is flanked to the northwest by Gunstock Mountain, the site of the Gunstock Mountain Resort ski area. The summit of Belknap Mountain features an active fire tower. Belknap Mountain stands within the watershed of the Merrimack River, which drains into the Gulf of Maine in M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New England Fifty Finest
The New England Fifty Finest is a list of mountains in New England, used in the mountaineering sport of peak bagging. The list comprises the 50 summits with the highest topographic prominence — a peak's height above the lowest contour which encloses that peak and no higher peak. The list includes 20 peaks in Maine, 15 in Vermont, 14 in New Hampshire, and one in Massachusetts. This list differs substantially from lists of peaks by elevation, such as the Four-thousand footers, New England 4000 Footers. For instance, only one peak in the Presidential Range is on this list because the others do not have a major prominence, being connected to Mount Washington (New Hampshire), Mount Washington by ridgelines that are nowhere below . Mount Washington has an elevation above sea level of but has a prominence of about because it stands that high above its key col — the lowest ground on the ridge line connecting Washington to the higher peaks of the southern Appalachian Mountains.

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metamorphic Rock
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and distorti ...

Transform Fault
A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly horizontal. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone. A transform fault is a special case of a ''strike-slip fault'' that also forms a plate boundary. Most such faults are found in oceanic crust, where they accommodate the lateral offset between segments of divergent boundaries, forming a zigzag pattern. This is a result of oblique seafloor spreading where the direction of motion is not perpendicular to the trend of the overall divergent boundary. A smaller number of such faults are found on land, although these are generally better-known, such as the San Andreas Fault and North Anatolian Fault. Nomenclature Transform boundaries are also known as conservative plate boundaries because they involve no addition or loss of lithosphere at the Earth's surface. Background Geophysicist ...

Year
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Igneous
Igneous rock (derived from the Latin word ''ignis'' meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust. Geological significance Igneous and metamorphic rocks make up 90–95% of the top ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Suncook River
The Suncook River is a river located in central New Hampshire in the United States. It is a tributary of the Merrimack River, which flows to the Gulf of Maine. Course The Suncook River begins at the outlet of Crystal Lake in the town of Gilmanton, New Hampshire. The village of Gilmanton Ironworks is located at the lake's outlet. The Suncook flows south two miles to the Suncook Lakes (Upper and Lower) in Barnstead. Below the lakes, the river passes through the village of Center Barnstead and enters the town of Pittsfield, whose village is centered on a 19th century dam on the river. The river continues south through the towns of Chichester and Epsom, and then forms the town boundary between Pembroke and Allenstown. Shortly before reaching the Merrimack River, the Suncook drops in , a natural waterpower site that led to the growth of the village of Suncook. 2006 flood On May 16, 2006, the Suncook River, responding to the highest rainfall amounts in at least 70 years (more ...
