McGinnis Mountain
McGinnis Mountain, also known as Mount McGinnis, is a mountain summit located in the Boundary Ranges, in the U.S. state of Alaska. The peak is situated near the toe of the Mendenhall Glacier, within Tongass National Forest, north-northwest of Juneau, Alaska, and north of Juneau International Airport. Although modest in elevation, relief is significant since the mountain rises up from sea level at Auke Bay in less than five miles. McGinnis Mountain is often seen and photographed with Stroller White Mountain, a summit to the north because they are together in the background behind Mendenhall Lake, a popular tourist and recreation area. History The mountain's name was officially adopted in 1930 by the United States Geological Survey McGinnis Mountain takes its name from McGinnis Creek, which drains its northern slopes. McGinnis Creek in turn was originally named ''McInnis River'' in 1891 by John McInnis and Edward Brennan who had staked claims in the area. In 1903, the name was ...

Coast Mountains
The Coast Mountains (french: La chaîne Côtière) are a major mountain range in the Pacific Coast Ranges of western North America, extending from southwestern Yukon through the Alaska Panhandle and virtually all of the Coast of British Columbia south to the Fraser River. The mountain range's name derives from its proximity to the sea coast, and it is often referred to as the Coast Range. The range includes volcanic and non-volcanic mountains and the extensive ice fields of the Pacific and Boundary Ranges, and the northern end of the volcanic system known as the Cascade Volcanoes. The Coast Mountains are part of a larger mountain system called the Pacific Coast Ranges or the Pacific Mountain System, which includes the Cascade Range, the Insular Mountains, the Olympic Mountains, the Oregon Coast Range, the California Coast Ranges, the Saint Elias Mountains and the Chugach Mountains. The Coast Mountains are also part of the American Cordilleraa Spanish term for an extensive chain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topographic Relief
Terrain or relief (also topographical relief) involves the vertical and horizontal dimensions of land surface. The term bathymetry is used to describe underwater relief, while hypsometry studies terrain relative to sea level. The Latin word (the root of ''terrain'') means "earth." In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns. Importance The understanding of terrain is critical for many reasons: * The terrain of a region largely determines its suitability for human settlement: flatter alluvial plains tend to have better farming soils than steeper, rockier uplands. * In terms of environmental quality, agriculture, hydrology and other interdisciplinary sciences; understanding the terrain of an area assists the understanding of watershed boundaries, drai ...

Mountains Of Alaska
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 and ...

Mount Wrather (Alaska)
Mount Wrather is a mountain summit located in the Boundary Ranges, in the U.S. state of Alaska. The peak is situated within Tongass National Forest, immediately east of the Mendenhall Glacier, north of Juneau, Alaska, and north of Juneau International Airport. Although modest in elevation, relief is significant since the mountain rises up from sea-level at Auke Bay in less than nine miles. The mountain's name was officially adopted in 1968 by the USGS to honor William Embry Wrather (1883–1963), the 6th Director of the United States Geological Survey from 1943 to 1956. Climate Based on the Köppen climate classification, Mount Wrather is located in a subarctic climate zone with cold, snowy winters, and mild summers. Temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports the Mendenhall Glacier on its west aspect, and Juneau Icefield to the mountain's northeast. June and July are the best months for climbing in terms of catching fav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bullard Mountain
Bullard Mountain is a mountain summit located in the Boundary Ranges, in the U.S. state of Alaska. The peak is situated immediately east of the terminus of Mendenhall Glacier, within Tongass National Forest, north-northwest of Juneau, and northeast of Juneau International Airport. McGinnis Mountain lies on the opposite side of the glacier, and Heintzleman Ridge lies to the south. Bullard Mountain is often seen and photographed with Mount Wrather, a summit to the north because they are together in the background behind Mendenhall Lake, a popular tourist and recreation area. Although modest in elevation, relief is significant since the mountain rises from this nearly sea-level lake in less than two miles. Precipitation runoff from the mountain drains into the lake via Nugget Creek and Nugget Falls. Bullard Mountain is named for Benjamin Bullard (1848-1933), a mining engineer who, in 1907, began mining on Nugget Creek where he later built a hydroelectric power plant.''Dictiona ...

Geography Of Alaska
Alaska occupies the northwestern portion of the North American continent and is bordered only by Canada on the east. It is one of two U.S. states not bordered by another state; Hawaii is the other. Alaska has more ocean coastline than all of the other U.S. states combined. About of Canadian territory separate Alaska from Washington state. Alaska is thus an exclave of the United States that is part of the continental U.S. and the U.S. West Coast, but is not part of the contiguous U.S. Alaska is also the only state, other than Hawaii, whose capital city is accessible only via ship or air, because no roads connect Juneau to the rest of the continent. The state is bordered by Yukon and British Columbia, Canada to the east, the Gulf of Alaska and the Pacific Ocean to the south, Russia ( Chukotka Autonomous Okrug), Bering Sea, the Bering Strait, and Chukchi Sea to the west, and the Beaufort Sea and the Arctic Ocean to the north. Because it extends into the Eastern Hemisphere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Juneau International Airport
Juneau International Airport is a city-owned, public-use airport and seaplane base located seven nautical miles (8 mi, 13 km) northwest of the central business district of Juneau, a city and borough in the U.S. state of Alaska that has no direct road access to the outside world. The airport serves as a regional hub for all air travel, from bush carriers to major U.S. air carriers such as Alaska Airlines. The National Plan of Integrated Airport Systems for 2015-2019 categorized it as a ''primary commercial service (nonhub)'' airport based on 353,048 enplanements (boardings) in 2012. As per the Federal Aviation Administration, this airport had 378,741 passenger enplanements in calendar year 2008, 337,038 in 2009, and 344,057 in 2010. History During World War II, Juneau Airport was used by the United States Army Air Forces as a transport link between the combat bases being established in the Aleutians and airfields in the mainland United States. It was also used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boundary Ranges
The Boundary Ranges, also known in the singular and as the Alaska Boundary Range, are the largest and most northerly subrange of the Coast Mountains. They begin at the Nass River, near the southern end of the Alaska Panhandle in the Canadian province of British Columbia and run to the Kelsall River, near the Chilkoot Pass, beyond which are the Alsek Ranges of the Saint Elias Mountains, and northwards into the Yukon Territory flanking the west side of the Yukon River drainage as far as Champagne Pass, north of which being the Yukon Ranges. To their east are the Skeena Mountains and Stikine Plateau of the Interior Mountains complex that lies northwest of the Interior Plateau; the immediately adjoining subregion of the Stikine Plateau is the Tahltan Highland. To their northeast is the Tagish Highland, which is a subregion of the Yukon Plateau. Both highlands are considered in some descriptions as included in the Coast Mountains.
