Mianus River Gorge
The Mianus River Gorge is a nature preserve in Bedford, New York jointly owned by The Nature Conservancy and Mianus River Gorge, Inc.. The first were purchased by the Preserve, with help from the Conservancy, their first land preservation deal. It has grown over the years and is still managed by Mianus River Gorge, Inc. In March 1964, it was designated a National Natural Landmark for its old growth climax hemlock forest and the gorge of the Mianus River. History In 1954, Gloria and Anthony Anable reached out for help from The Nature Conservancy which pledged $7,500 to help purchase of land in the gorge, its first land preservation purchase. In 1990, were donated as part of a development deal. In 2007, The Nature Conservancy purchased of adjacent wetlands to protect the gorge and its watershed. Geology The gorge is a periglacial formation, carved by streams as the glacier retreated. It contains several types of bedrock including Bedford Augen Gneiss (an igneous int ...

Bedford (town), New York
Bedford is a town in Westchester County, New York. The population was 17,335 at the 2010 census. Bedford is located in the northeastern part of Westchester County and contains the three hamlets of Bedford Hills, Bedford, and Katonah. History The town of Bedford was founded on December 23, 1680, when 22 Puritans from Stamford, Connecticut, purchased a tract of land three miles square known as the "Hopp Ground" from Chief Katonah and several other Native Americans for coats, blankets, wampum and cloth. Bedford was made a part of Connecticut in 1697 when a patent fixed the boundaries as a six-mile square. Only when King William III of England issued a royal decree in 1700 settling a boundary dispute did Bedford become part of New York. The town served as the county seat of Westchester County during the American Revolutionary War after the Battle of White Plains, until Bedford was burned by the British in July 1779. British forces led by Lieutenant Colonel Banastre Tarleton burned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating al ...

Nature Conservancy Preserves In New York (state)
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

List Of National Natural Landmarks In New York
__NOTOC__ The National Natural Landmarks in New York include 28 of the almost 600 National Natural Landmarks (NNLs) in the United States. Twenty-six landmarks are contained entirely within New York; the two exceptions are the Palisades of the Hudson which extends along the Hudson River into New Jersey, and the Chazy Fossil Reef which spans several Lake Champlain islands belonging to both New York and Vermont. New York's NNLs cover unique fluvioglacial landform, landforms carved by glacial meltwater, a rare meromictic lake, several exposed fossil sites, and the largest open fault (geology), fault system in the United States. The state's first NNLs, Bergen-Byron Swamp and Mianus River Gorge, were designated in 1964 and are the oldest NNLs in the nation; New York's newest NNL is the Albany Pine Bush, designated in 2014. Owners include private individuals, non-governmental conservation organizations, and several municipal, state and federal agencies. Designation as a NNL does not guara ...

Rose Petal Hypothesis
A rose is either a woody perennial flowering plant of the genus ''Rosa'' (), in the family Rosaceae (), or the flower it bears. There are over three hundred species and tens of thousands of cultivars. They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp prickles. Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwestern Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses. Etymology The name ''rose'' comes from Lati ...

Bow Hunting
Bowhunting (or bow hunting) is the practice of hunting game animals by archery. Many indigenous peoples have employed the technique as their primary hunting method for thousands of years, and it has survived into contemporary use for sport and hunting. Modern history The last of the Yahi tribe, an indigenous man known as Ishi, came out of hiding in California in 1911. His doctor, Saxton Pope, learned many of Ishi's traditional archery skills, and popularized them. The Pope and Young Club, founded in 1961 and named in honor of Pope and his friend, Arthur Young, became one of North America's leading bowhunting and conservation organizations. Founded as a nonprofit scientific organization, the Club was patterned after the Boone and Crockett Club and advocated responsible bowhunting by promoting quality, fair chase hunting, and sound conservation practices. Modern game archery owes much of its success to Fred Bear, an American bow hunter and bow manufacturer. Equipment Arrows, bow ...

Deer
Deer or true deer are hoofed ruminant mammals forming the family Cervidae. The two main groups of deer are the Cervinae, including the muntjac, the elk (wapiti), the red deer, and the fallow deer; and the Capreolinae, including the reindeer (caribou), white-tailed deer, the roe deer, and the moose. Male deer of all species (except the water deer), as well as female reindeer, grow and shed new antlers each year. In this they differ from permanently horned antelope, which are part of a different family (Bovidae) within the same order of even-toed ungulates (Artiodactyla). The musk deer (Moschidae) of Asia and chevrotains (Tragulidae) of tropical African and Asian forests are separate families that are also in the ruminant clade Ruminantia; they are not especially closely related to Cervidae. Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology, religion, and literature throughout history, as well as in heraldry, such as ...

Pegmatite
A pegmatite is an igneous rock showing a very coarse texture, with large interlocking crystals usually greater in size than and sometimes greater than . Most pegmatites are composed of quartz, feldspar, and mica, having a similar silicic composition to granite. However, rarer intermediate composition and mafic pegmatites are known. Many of the world's largest crystals are found within pegmatites. These include crystals of microcline, quartz, mica, spodumene, beryl, and tourmaline. Some individual crystals are over long. Most pegmatites are thought to form from the last fluid fraction of a large crystallizing magma body. This residual fluid is highly enriched in volatiles and trace elements, and its very low viscosity allows molecules to migrate rapidly to join an existing crystal rather than coming together to form new crystals. This allows a few very large crystals to form. While most pegmatites have a simple composition of minerals common in ordinary igneous rock, a few ...

Cameron's Line
Cameron's Line is an Ordovician suture fault in the northeast United States which formed as part of the continental collision known as the Taconic orogeny around 450 mya. Named after Eugene N. Cameron, who first described it in the 1950s, it ties together the North American continental craton, the prehistoric Taconic Island volcanic arc, and the bottom of the ancient Iapetus Ocean. Location Cameron's Line winds southward out of New England through Western Connecticut. It has been identified in western Connecticut near Ridgefield before it heads into the Bronx, along the East River in Manhattan, through New York Bay, Staten Island and into New Jersey. Geology The basement rocks of the Manhattan Formation located on the western side of Cameron's line are metamorphosed sedimentary rocks and can be thought of as the remnants of the edge of the North American continent from 1 billion years ago. They were formed in roughly this location (autochthonous) and have been tectonically s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gneiss
Gneiss ( ) is a common and widely distributed type of metamorphic rock. It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks. Gneiss forms at higher temperatures and pressures than schist. Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands and without a distinct cleavage. Gneisses are common in the ancient crust of continental shields. Some of the oldest rocks on Earth are gneisses, such as the Acasta Gneiss. Description Orthogneiss from the Czech Republic In traditional English and North American usage, a gneiss is a coarse-grained metamorphic rock showing compositional banding (gneissic banding) but poorly developed schistosity and indistinct cleavage. In other words, it is a metamorphic rock composed of mineral grains easily seen with the unaided eye, which form obvious compositional layers, but which has only a weak tendency to fracture ...
