Kenai Peninsula
The Kenai Peninsula ( Dena'ina: ''Yaghenen'') is a large peninsula jutting from the coast of Southcentral Alaska. The name Kenai (, ) is derived from the word "Kenaitze" or "Kenaitze Indian Tribe", the name of the Native Athabascan Alaskan tribe, the Kahtnuht’ana Dena’ina ("People along the Kahtnu (Kenai River)"), who historically inhabited the area. They called the Kenai Peninsula ''Yaghanen'' ("the good land"). Geography The peninsula extends about southwest from the Chugach Mountains, south of Anchorage. It is separated from the mainland on the west by Cook Inlet and on the east by Prince William Sound. Most of the peninsula is part of the Kenai Peninsula Borough. Athabaskan and Alutiiq Native groups lived on the peninsula for thousands of years prior to Gerasim Izmailov becoming the first European to explore and map the area in 1789. The glacier-covered Kenai Mountains, rising , run along the southeast spine of the peninsula along the coast of the Gulf of Alaska. Much ...

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] |

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] |
Fourth Of July
Independence Day (colloquially the Fourth of July) is a federal holiday in the United States commemorating the Declaration of Independence, which was ratified by the Second Continental Congress on July 4, 1776, establishing the United States of America. The Founding Father delegates of the Second Continental Congress declared that the Thirteen Colonies were no longer subject (and subordinate) to the monarch of Britain, King George III, and were now united, free, and independent states. The Congress voted to approve independence by passing the Lee Resolution on July 2 and adopted the Declaration of Independence two days later, on July 4. Independence Day is commonly associated with fireworks, parades, barbecues, carnivals, fairs, picnics, concerts, baseball games, family reunions, political speeches, and ceremonies, in addition to various other public and private events celebrating the history, government, and traditions of the United States.

Resurrection Bay
Resurrection Bay, also known as Blying Sound, and Harding Gateway in its outer reaches, is a fjord on the Kenai Peninsula of Alaska, United States. Its main settlement is Seward, located at the head of the bay. The bay received its name from Alexandr Baranov, who was forced to retreat into the bay during a bad storm in the Gulf of Alaska. When the storm settled it was Easter Sunday, so the bay and nearby Resurrection River were named in honor of it. Harding Gateway refers to the passage between Rugged and Cheval Islands. Resurrection Bay is the location of Caines Head, at the summit of which Fort McGilvray is situated 650 feet (198 meters) above sea level. This fortification was constructed by the United States Armed Forces to defend against a possible invasion by the Imperial Japanese Army during World War II. The bay remains ice-free even in winter, making it easily navigable. It is the central theme of the song "Resurrection Bay" by John Craigie on his album '' Montana Tal ...

Chugach National Forest
The Chugach National Forest is a United States National Forest in south central Alaska. Covering portions of Prince William Sound, the Kenai Peninsula and the Copper River Delta, it was formed in 1907 from part of a larger forest reserve. The Chugach includes extensive shorelines, glaciers, forests and rivers, much of which is untouched by roads or trails. It hosts numerous bird, mammal and marine species, including extensive shorebird habitat and a bald eagle population larger than the contiguous 48 states combined. Human industry in the forest includes extensive tourism and some mining and oil and gas operations. History The area that is now Chugach was settled by the Alutiiq thousands of years ago. It was first visited by Europeans in the mid-1700s and soon settled by Russian fur traders, who trapped the native sea otters. In 1867, the US purchased Alaska from Russia and gold was found in 1888. In 1907, the Chugach National Forest was created from a portion of forest rese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
