Begich Peak
Begich Peak is a mountain summit located in the Chugach Mountains, in Anchorage Municipality in the U.S. state of Alaska. The peak is situated in Chugach National Forest, north of Portage Lake, northwest of Whittier, Alaska, east of Portage Peak, and southwest of Boggs Peak. The mountain's name was officially adopted in 1976 by the United States Geological Survey to commemorate Alaska Congressman Nick Begich (1932–1972), who was a member of the U.S. House of Representatives when he disappeared along with House majority leader Hale Boggs and two others on October 16, 1972, during an airplane flight from Anchorage to Juneau. Neither the plane's wreckage nor the pilot's and passengers' remains were ever found. The ''Begich, Boggs Visitor Center'' is located at Portage Lake. Climate Based on the Köppen climate classification, Begich Peak is located in a subarctic climate zone with cold, snowy winters, and mild summers. Temperatures can drop below −20 °C with wind chill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turnagain Arm
Turnagain Arm ( Dena'ina: ''Tutl'uh'') is a waterway into the northwestern part of the Gulf of Alaska. It is one of two narrow branches at the north end of Cook Inlet, the other being Knik Arm. Turnagain is subject to climate extremes and large tide ranges. Geography Turnagain extends in an east-west direction, and is between long. It forms part of the northern boundary of Kenai Peninsula, and reaches on the east to within of Passage Canal, a western branch of Prince William Sound. Turnagain is characterized by remarkably large tides of up to 40 feet (12 meters) which are the largest tides in the United States. The flood tide often begins with a tidal bore especially on large tides with a strong east wind, which has a height of at times, and runs in from the west at a speed of an hour. At low tide, the arm becomes a broad mud flat, cut by the stream channels. Historically small steamers entered and left on high water though the practice is rare at best since most if not all the ...

Majority Leader Of The United States House Of Representatives
Party leaders of the United States House of Representatives, also known as floor leaders, are congresspeople who coordinate legislative initiatives and serve as the chief spokespersons for their parties on the House floor. These leaders are elected every two years in secret balloting of their party caucuses or conferences: the House Democratic Caucus and the House Republican Conference. Depending on which party is in power, one party leader serves as majority leader and the other as minority leader. Unlike the Senate Majority Leader, the House Majority Leader is the second highest-ranking member of their party's House caucus, behind the Speaker of the House. The Majority Leader is responsible for setting the annual legislative agenda, scheduling legislation for consideration, and coordinating committee activity. The Minority Leader serves as floor leader of the opposition party, and is the minority counterpart to the Speaker. The Minority Leader also speaks for the minority p ...

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 ...

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] |

Twentymile River
The Twentymile River is a river near the Kenai Peninsula in Alaska. It rises in a remote valley from meltwater of several small glaciers in the Chugach Mountains and flows out into a large, wide valley where it receives the water of the Moraine and Glacier rivers. Eventually, the river empties into Turnagain Arm after flowing to a broad marshy delta alongside the deltas of Portage Creek Portage Creek is a census-designated place (CDP) in Dillingham Census Area, Alaska, United States.

Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...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] |
Hale Boggs
Thomas Hale Boggs Sr. (February 15, 1914 – disappeared October 16, 1972; declared dead December 29, 1972) was an American Democratic politician and a member of the U.S. House of Representatives from New Orleans, Louisiana. He was the House majority leader and a member of the Warren Commission. In 1972, while still majority leader, Boggs was on a fundraising drive in Alaska when the twin engine airplane he was travelling in (along with Alaska congressman Nick Begich and two others) disappeared en route from Anchorage to Juneau, Alaska. Early life and education Boggs was born in Long Beach in Harrison County on the Mississippi Gulf Coast, the son of Claire Josephine (Hale) and William Robertson "Will" Boggs. Boggs was educated at Tulane University where he received a bachelor's degree in journalism in 1934 and a law degree in 1937. He first practiced law in New Orleans but soon became a leader in the movement to break the power of the political machine of U.S. Senator Huey Pi ...

Chugach Mountains
The Chugach Mountains of southern Alaska are the northernmost of the several mountain ranges that make up the Pacific Coast Ranges of the western edge of North America. The range is about long and wide, and extends from the Knik and Turnagain Arms of the Cook Inlet on the west to Bering Glacier, Tana Glacier, and the Tana River on the east. It is bounded on the north by the Matanuska, Copper, and Chitina rivers. The highest point of the Chugach Mountains is Mount Marcus Baker, at , but with an average elevation of , most of its summits are not especially high. Even so, its position along the Gulf of Alaska ensures more snowfall in the Chugach than anywhere else in the world, an annual average of over 1500 cm (800 in).Steep, Freeskiing Documentary, 2007 The mountains are protected in the Chugach State Park and the Chugach National Forest. Near to Anchorage, they are a popular destination for outdoor activities. The Richardson Highway, Seward Highway, Portage G ...
