Breccia Peak (Wyoming)
Breccia Peak is a mountain in the southern Absaroka Range of the Rocky Mountains. It is located in Teton County in the U.S. state of Wyoming, close to the southwest border of the Teton Wilderness within the Bridger-Teton National Forest. Geography Breccia Peak is located about north of Togwotee Pass, part of the Great Continental Divide which connects Jackson Hole from the west to the Wind River valley in the east. The plateau-like summit contains the steep and rocky Breccia Cliffs on its west and north faces, while a mainly grassy face exists to the east and south. Breccia Peak is the most prominent mountain in the immediate area, topping Buffalo Fork Peak to its north by about 200 feet (61 m). Higher peaks can be found along the Teton Range, located more than 30 miles (48 km) to the west. About southwest of Breccia Peak lies Lost Lake, located at an elevation of about . This is a small but very scenic lake where the Breccia Cliffs reflect off the water during certain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Upper Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Teton County, Wyoming
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain ...

Survey Marker
Survey markers, also called survey marks, survey monuments, or geodetic marks, are objects placed to mark key survey points on the Earth's surface. They are used in geodetic and land surveying. A ''benchmark'' is a type of survey marker that indicates elevation (vertical position). Horizontal position markers used for triangulation are also known as ''triangulation stations''. '' Benchmarking'' is the hobby of "hunting" for these marks. Types All sorts of different objects, ranging from the familiar brass disks to liquor bottles, clay pots, and rock cairns, have been used over the years as survey markers. Some truly monumental markers have been used to designate tripoints, or the meeting points of three or more countries. In the 19th century, these marks were often drill holes in rock ledges, crosses or triangles chiselled in rock, or copper or brass bolts sunk into bedrock. Today in the United States, the most common geodetic survey marks are cast metal disks with stamped l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Moran
Mount Moran () is a mountain in Grand Teton National Park of western Wyoming, USA. The mountain is named for Thomas Moran, an American western frontier landscape artist. Mount Moran dominates the northern section of the Teton Range rising above Jackson Lake. Several active glaciers exist on the mountain with Skillet Glacier plainly visible on the monolithic east face. Like the Middle Teton in the same range, Mount Moran's face is marked by a distinctive basalt intrusion known as the Black Dike. Climbing Mount Moran is a massive and impressive mountain which would make it attractive to mountaineers. However, the comparative difficulty of the approach to the climbs makes it a much less popular climb than the Grand Teton and other peaks to the south. No trails to Mount Moran have been maintained for over twenty years, and any approach overland requires a great deal of bushwhacking through vegetation, deadfalls, and bogs along the perimeter of Leigh Lake. Instead, most climb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backcountry Skiing
Backcountry skiing ( US), also called off-piste (Europe), alpine touring, or out-of-area, is skiing in the backcountry on unmarked or unpatrolled areas either inside or outside a ski resort's boundaries. This contrasts with alpine skiing, which is typically done on groomed trails benefiting from a ski patrol. Unlike ski touring, backcountry skiing can include the use of ski lifts including snowcats and helicopters. Recent improvements in equipment have increased the popularity of the sport. Terminology The terms "backcountry" and "off-piste" refer to where the skiing is being done, while terms like ski touring, ski mountaineering, telemark, freeriding, and extreme skiing describe what type of skiing is being done. Terms for backcountry skiing exist according to how the terrain is accessed, and how close it is to services. Backcountry can include the following: * Frontcountry: off-trail within ski area boundaries where ski lifts and emergency services are close at hand. * Slackc ...

Greater Yellowstone Ecosystem
The Greater Yellowstone Ecosystem (GYE) is one of the last remaining large, nearly intact ecosystems in the northern temperate zone of the Earth. It is located within the northern Rocky Mountains, in areas of northwestern Wyoming, southwestern Montana, and eastern Idaho, and is about . Yellowstone National Park and the Yellowstone Caldera 'hotspot' are within it. The area is a flagship site among conservation groups that promote ecosystem management. The Greater Yellowstone Ecosystem (GYE) is one of the world's foremost natural laboratories in landscape ecology and Holocene geology, and is a world-renowned recreational destination. It is also home to the diverse native plants and animals of Yellowstone. History Yellowstone National Park boundaries were drawn in 1872 with the intent to include all the known geothermal basins in the region. As landscape ecology considerations were not incorporated into original boundary, revisions were suggested to conform more closely to natur ...

Mineral Alteration
Mineral alteration refers to the various natural processes that alter a mineral's chemical composition or crystallography. Mineral alteration is essentially governed by the laws of thermodynamics related to energy conservation, relevant to environmental conditions, often in presence of catalysts, the most common and influential being water (H2O). The degree and scales of time in which different minerals alter vary depending on the initial product and its physical properties and susceptibility to alteration. Some minerals such as quartz and zircon are highly resistant to alteration under normal weathering conditions. Yet quartz may alter to stishovite with intense pressure, and zircon to ''crytolite'' (a metamict zircon) with amount of radioactive components and time. In some circumstances, a mineral alters while maintaining its outer form known as a pseudomorph. Mineral alteration is distinctly different than the rock alteration process metamorphism. It also differs from weather ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porphyry (geology)
Porphyry ( ) is a textural term for an igneous rock consisting of coarse-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate-rich, generally aphanitic matrix or groundmass. The larger crystals are called phenocrysts. In its non-geologic, traditional use, the term ''porphyry'' refers to the purple-red form of this stone, valued for its appearance. The term ''porphyry'' is from the Ancient Greek (), meaning "purple". Purple was the color of royalty, and the "imperial porphyry" was a deep purple igneous rock with large crystals of plagioclase. Some authors claimed the rock was the hardest known in antiquity. Thus, "imperial"-grade porphyry was prized for monuments and building projects in Imperial Rome and thereafter. Subsequently, the name was given to any igneous rocks with large crystals. The adjective ''porphyritic'' now refers to a certain texture of igneous rock regardless of its chemical and mineralogical composition. Its chief characteris ...

Rhyodacite
Rhyodacite is a volcanic rock intermediate in composition between dacite and rhyolite. It is the extrusive equivalent of those plutonic rocks that are intermediate in composition between monzogranite and granodiorite. Rhyodacites form from rapid cooling of lava relatively rich in silica and low in alkali metal oxides. Description Under IUGS guidelines, rhyodacites are not formally defined in either the QAPF classification, used to classify igneous rocks by their mineral content, or the TAS classification, used to classify volcanic rocks chemically. However, the IUGS allows the use of the term to describe rocks close to the boundary between the rhyolite and dacite fields in each classification scheme. Rhyodacite then describes a fine-grained igneous rock containing between 20% and 60% quartz and in which plagioclase makes up about two-thirds of the total feldspar content. Such a rock will contain between 69% and 72% silica by weight. The U.S. Geological Survey defines rhyodacite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
