Mount Healy
Mount Healy, also known in Denaʼina language as ''Dlel Neelghu Nodaadlghunee'' (meaning "mountains that are joined together"), is a 5,716-foot (1,742 meter) elevation mountain summit located in the Alaska Range, in Denali National Park and Preserve, in Alaska, Alaska, United States. It is situated immediately northwest of park headquarters and south of Healy, Alaska, Healy. The George Parks Highway and Alaska Railroad traverse the eastern base of this mountain as each passes through the Nenana River Gorge. Mount Healy's nearest neighbor, Sugar Loaf Mountain (Alaska), Sugar Loaf Mountain, is set to the east across the gorge, and the nearest higher peak is Fang Mountain, to the south-southwest. Mount Healy is a nine-mile-long, east–west trending ridge system of mostly loose rock with jagged peaks and spires. Vegetation ranges from Taiga, boreal forest at the base all the way up to barren alpine ridges and snowfields at the top. This area is very popular for day hikes due to its ...

Fang Mountain
Fang Mountain is a summit located in the Alaska Range, in Denali National Park and Preserve, in Alaska, Alaska, United States. It is situated southwest of park headquarters and northwest of Cantwell, Alaska, Cantwell, near the headwaters of the Savage River. This peak's local descriptive name was published in 1952 by the United States Geological Survey. Rarely climbed, Fang Mountain is an unattractive climbing destination because of dangerous, loose, rotten rock and a long approach.Dow Scoggins, ''Discoverig Denali'', iUniverse, 2004, page 88. Climate Based on the Köppen climate classification, Fang Mountain is located in a subarctic climate zone with long, cold, snowy winters, and mild summers. Temperatures can drop below −20 °C with wind chill factors below −30 °C. The months May through June offer the most favorable weather for climbing or viewing. Precipitation Surface runoff, runoff from the mountain drains north into Savage River, east into Riley Creek, or west into ...

Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50° to 70°N, poleward of the humid continental climates. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'', ''Dwd'' and ''Dsd''. Description This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below and in summer, the temperature may exceed . However, the summers are short; no more than three months of the year (but at least one month) must have a 24-hour average temperature of at least to fall into this category of climate, and the coldest month should ave ...

Mountains Of Denali National Park And Preserve
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 ...

Geology Of Alaska
The geology of Alaska includes Precambrian igneous and metamorphic rocks formed in offshore terranes and added to the western margin of North America from the Paleozoic through modern times. The region was submerged for much of the Paleozoic and Mesozoic and formed extensive oil and gas reserves due to tectonic activity in the Arctic Ocean. Alaska was largely ice free during the Pleistocene, allowing humans to migrate into the Americas. Geologic History, Stratigraphy & Tectonics Compared with other areas of the North American continent, Alaska formed in the recent geologic past. Until 200 million years ago, western North America terminated at the Rocky Mountains, 120 miles further inland than the current shoreline, until the addition of the Yukon-Tanana Terrane. The Birch Creek Schist is the oldest rock in Alaska's interior and forms the core of the Yukon-Tanana Terrane with muscovite-quartz schist, mica quartzite and graphite schist. This intensely folded and rock unit extends f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Tanana River
The Tanana River (Lower Tanana: Tth'eetoo', Upper Tanana: ''Tth’iitu’ Niign'') is a tributary of the Yukon River in the U.S. state of Alaska. According to linguist and anthropologist William Bright, the name is from the Koyukon (Athabaskan) ''tene no'', ''tenene'', literally "trail river". The river's headwaters are located at the confluence of the Chisana and Nabesna rivers just north of Northway in eastern Alaska. The Tanana flows in a northwest direction from near the border with the Yukon Territory, and laterally along the northern slope of the Alaska Range, roughly paralleled by the Alaska Highway. In central Alaska, it emerges into a lowland marsh region known as the Tanana Valley and passes south of the city of Fairbanks. In the marsh regions it is joined by several large tributaries, including the Nenana (near the city of Nenana) and the Kantishna. It passes the village of Manley Hot Springs and empties into the Yukon near the town of Tanana. Ice on the riv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
