Ice Mountain
Ice Mountain is a mountain ridge and algific talus slope that is part of a preserve near the community of North River Mills in Hampshire County, West Virginia, United States. It was designated a National Natural Landmark in 2012. Ice Mountain is protected by The Nature Conservancy and open for visits by small groups of hikers. It is nicknamed "Nature's Ice Box" and "Nature's Refrigerator" owing to its ice vents that release cool air all year long. Refrigeration The accumulated rock detritus at Ice Mountain's base forms a talus that is thick in some places. It creates a refrigeration effect. As cold air sinks into the talus pile during the cooler months it forms masses of ice and ice vents inside it. The ice vents are in a section about in length along Ice Mountain's southern flank. Cool air is expelled from the ice in the warmer months. Vent air temperatures vary throughout the year, but the mean annual temperature can be as low as 2 °C (35 °F). Within th ...

Gymnocarpium Appalachianum
''Gymnocarpium'' is a small genus of ferns, called oak ferns. It was once placed with various other groups, including the dryopteroid ferns and the athyrioid ferns. Cladistic analysis has demonstrated that ''Gymnocarpium'' and ''Cystopteris'' form a natural but relatively primitive clade that is basal to the asplenioid, thelypterioid, and athyrioid ferns comprehensively. ''Gymnocarpium'' sori are small, round and naked. These ferns generally have a slender, creeping rhizome under the surface of the ground, and fairly thin-textured fronds.

Cornus Canadensis
''Cornus canadensis'' is a species of flowering plant in the dogwood family Cornaceae, native to eastern Asia and North America. Common names include Canadian dwarf cornel, Canadian bunchberry, quatre-temps, crackerberry, and creeping dogwood. Unlike its relatives, which are for the most part substantial trees and shrubs, ''C. canadensis'' is a creeping, rhizomatous perennial growing to about tall. Description ''Cornus canadensis'' is a slow-growing herbaceous perennial growing tall, generally forming a carpet-like mat. The above-ground shoots rise from slender creeping rhizomes that are placed deep in the soil, and form clonal colonies under trees. The vertically produced above-ground stems are slender and unbranched. Produced near the terminal node, the leaves are shiny dark green and arranged oppositely on the stem, clustered with six leaves that often seem to be in a whorl because the internodes are compressed. The leaves consist of two types: two larger and four smal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Above Mean Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Glacial Period
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period ...
