Marcy Group
The Marcy Group, or Marcy Massif is a subset of the Great Range of the Adirondack Mountains, near Keene Valley, New York, United States. It consists of the High Peaks near Mount Marcy at the southern end of the Great Range, Allen Mountain, Cliff Mountain, Mount Colden, Gray Peak, Mount Haystack, Mount Redfield, and Mount Skylight, and the lesser peaks McDonnel Mountain, North River Mountains Peak, and Rist Mountain. Geology The group is unique for its formation and composition of minerals, particularly for its composition of anorthosite rock. The Marcy massif includes two separate groups of plutons, an eastern and western range. The western range is situated near the St. Regis and Long Lake quadrangles and the eastern Marcy group is sited near Jay Jays are a paraphyletic grouping of passerine birds within the family Corvidae. Although the term "jay" carries no taxonomic weight, most or all of the birds referred to as jays share a few similarities: they are s ...

Adirondacks Mount Marcy From Mount Haystack
The Adirondack Mountains ( ) are a massif of mountains in Northeastern New York which form a circular dome approximately wide and covering about . The region contains more than 100 peaks, including Mount Marcy, which is the highest point in New York at . The Adirondack High Peaks, a traditional list of 46 peaks over , are popular hiking destinations. There are over 200 named lakes with the number of smaller lakes, ponds, and other bodies of water reaching over 3,000. Among the named lakes around the mountains are Lake George, Lake Placid, and Lake Tear of the Clouds. The region has over of river. Although the mountains are formed from ancient rocks more than 1 billion years old, geologically, the mountains are relatively young and were created during recent periods of glaciation. Because of this, the Adirondacks have been referred to as "new mountains from old rocks." It is theorized that there is a hotspot beneath the region, which causes continued uplift at the rate of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Redfield
Mount Redfield is a mountain in the Adirondacks in the U.S. state of New York. It is the 15th-highest peak in New York, with an elevation of , and one of the 46 High Peaks in Adirondack Park. It is located in the town of Keene in Essex County, near Cliff Mountain and Mount Skylight. Surveyor Verplanck Colvin named the mountain after William C. Redfield, organizer and member of an expedition to Mount Marcy in 1837, and the first to guess that Marcy was the highest peak in the Adirondacks, and therefore in New York. The earliest recorded ascent was made in 1894 by mountain guide Ed Phelps and a guest whose name has not been recorded. There is no maintained trail on the mountain, but an unmarked trail begins at the Uphill Lean-to along the Calamity Brook Trail, and proceeds along Uphill Brook and a tributary stream to the summit.

North Hudson, New York
North Hudson is a town in Essex County, New York, United States. The population was 240 at the 2010 census. The town derives its name by being near the northern end of the Hudson River. The town is in the south-central part of the county and is south of Plattsburgh. North Hudson is within the Adirondack Park. History The region was first settled ''circa'' 1800. Early pioneers chose the southeastern part of the town. The town was formed in 1848 from the town of Moriah. Early industry was based on tanning, owing to the presence of hemlock bark from the forests. Later, the trees were harvested for wood pulp. By the end of the 19th century, the tourist trade began to predominate, especially at Underwood and Elk Lake. The theme park Frontier Town, a Wild West themed family tourist attraction, operated here from 1952 to 1998. The closure of Frontier Town had a severe negative impact on the town's economy. In 2018, Frontier Town reopened as Adirondack campground and day-use area. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Mountain
Hurricane Mountain is a mountain near Keene in the north of the High Peaks region of the Adirondacks in New York, United States. It is considered to boast some of the most impressive views of any of the lesser peaks; this is due to its prominence, and because its summit was cleared by Verplanck Colvin in the course of his early survey of the Adirondacks.Goodwin, Tony, ed., ''Adirondack Trails, High Peaks Region'', Lake George, New York: Adirondack Mountain Club, 2004. On a clear day, the length of Lake Champlain and the Green Mountains of Vermont are visible to the east, and many of the High Peaks can be seen to the south through the northwest. There is a disused fire tower on the top. There are three trails to the summit, from the north (unmaintained), south and east. Atop the mountain is the Hurricane Mountain Fire Observation Station, added to the National Register of Historic Places The National Register of Historic Places (NRHP) is the Federal government of the ...

Jay, New York
Jay is a town in Essex County, New York, United States. The population was 2,506 at the 2010 census. The town is named after John Jay, governor of New York when the town was formed. The town is on the northern border of Essex County and is southwest of Plattsburgh, south of Montreal, and north of Albany. Jay is located inside the Adirondack Park. History The area was originally known as "Mallory's Bush", after the principal settlement, based on early settler Nathaniel Mallory, who arrived around 1797.. The town of Jay, named in honor of New York Governor John Jay, was formed in January 1798 from part of the town of Willsboro. Afterwards, part of Jay was used to form, in whole or part, the towns of Keene (1808), Elizabethtown and Wilmington (1821). In 1822, the town was increased by territory from the town of Chateaugay (now in Franklin County), and the town of Peru (now in Clinton County). Lumber production and iron ore extraction were important to the early economy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quadrangle (geography)
A "quadrangle" is a topographic map produced by the United States Geological Survey (USGS) covering the United States. The maps are usually named after local physiographic features. The shorthand "quad" is also used, especially with the name of the map; for example, "the Ranger Creek, Texas quad". A quadrangle is defined by north and south boundaries of Circle of latitude, constant latitude (which are not great circles so are curved), and by east and west boundaries of constant longitude. From approximately 1947–1992, the USGS produced the 7.5 minute series, with each map covering an area one-quarter of the older 15-minute quad series, which it replaced. A 7.5 minute quadrangle map covers an area of . Both map series were produced via photogrammetry, photogrammetric analysis of aerial photography using stereoplotters supplemented by field surveys. These maps employ the 1927 North American Datum (NAD27); conversion or a change in settings is necessary when using a GPS which by d ...

Plutons
In geology, an igneous intrusion (or intrusive body or simply intrusion) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. Intrusions have a wide variety of forms and compositions, illustrated by examples like the Palisades Sill of New York and New Jersey; the Henry Mountains of Utah; the Bushveld Igneous Complex of South Africa; Shiprock in New Mexico; the Ardnamurchan intrusion in Scotland; and the Sierra Nevada Batholith of California. Because the solid country rock into which magma intrudes is an excellent insulator, cooling of the magma is extremely slow, and intrusive igneous rock is coarse-grained (phaneritic). Intrusive igneous rocks are classified separately from extrusive igneous rocks, generally on the basis of their mineral content. The relative amounts of quartz, alkali feldspar, plagioclase, and feldspathoid is particularly important in classifying intrusive igneous rocks. Intrusions mu ...

Massif
A massif () is a principal mountain mass, such as a compact portion of a mountain range, containing one or more summits (e.g. France's Massif Central). In mountaineering literature, ''massif'' is frequently used to denote the main mass of an individual mountain. As a purely scientific term in geology, however, a "massif" is separately and more specifically defined as a section of a planet's crust (geology), crust that is demarcated by geologic fault, faults or lithospheric flexure, flexures. In the plate tectonics, movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. A massif is a smaller structural unit than a tectonic plate and is considered the fourth-largest driving force in geomorphology. The word "massif" originates from French (in which the word also means "massive"), where it is used to refer to a large mountain mass or compact group of connected mountains forming an independent portion of a range. The Cydonia (regi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anorthosite
Anorthosite () is a phaneritic, intrusive rock, intrusive igneous rock characterized by its composition: mostly plagioclase feldspar (90–100%), with a minimal mafic component (0–10%). Pyroxene, ilmenite, magnetite, and olivine are the mafic minerals most commonly present. Anorthosites are of enormous geologic interest, because it is still not fully understood how they form. Most models involve fractional crystallization (geology), separating plagioclase crystals based on their density. Plagioclase crystals are usually less dense than magma; so, as plagioclase crystallizes in a magma chamber, the plagioclase crystals float to the top, concentrating there. Anorthosite on Earth can be divided into five types: # Archean anorthosites # Proterozoic anorthosite (also known as massif or massif-type anorthosite) – the most abundant type of anorthosite on Earth # Layers within Layered intrusion, Layered Intrusions (e.g., Bushveld Igneous Complex, Bushveld and Stillwater igneous com ...

Mount Skylight
Mount Skylight is a mountain in the Adirondacks in the U.S. state of New York. Skylight is the fourth-highest peak in New York, with an elevation of , and one of the 46 High Peaks in Adirondack Park. It is located in the town of Keene in Essex County. The mountain was given its name by artist Frederick S. Perkins and guide Orson Schofield Phelps in 1857, due to a rock formation on the peak resembling a window. Phelps would later make the first known ascent of the peak with surveyor Verplanck Colvin and two others on August 28, 1873. Hiking trails A single trail goes up to the mountain's summit from the Four Corners junction between Skylight and Mount Marcy, its northern neighbor. Three other trails lead to the intersection. Most commonly, hikers approach from the west, via the Feldspar Brook Trail from the campsites at the Flowed Lands and climb the peak in conjunction with a visit to Lake Tear of the Clouds, and a climb up neighboring, trail-less Gray Peak. The distance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Haystack
Mount Haystack is a mountain in the Great Range of the Adirondack Mountains of New York. With an elevation of , it is the third-highest mountain in New York and one of the 46 High Peaks in Adirondack Park. It is located in the town of Keene in Essex County. The first recorded ascent of the mountain was made by mountain guide Orson Schofield Phelps in 1849, accompanied by Almeron Oliver and George Etsy. Phelps gave the mountain its current name based on its appearance to a haystack, and later cut the first trail to the summit in 1873. The summit is an alpine zone above the treeline, which offers a view of nearby Mount Marcy and Panther Gorge. Two trails can be used to access the summit of Haystack. The mountain can be approached from the north by following the Johns Brook Trail from the Garden parking area in Keene Valley to the Phelps Trail, passing the DEC Interior Outpost and Johns Brook Lodge, and then following the State Range Trail from a junction between the two.
