Coastal Migration (Americas)
The coastal migration hypothesis is one of two leading hypotheses about the settlement of the Americas at the time of the Last Glacial Maximum. It proposes a migration route involving watercraft, via the Kurile island chain, along the coast of Beringia and the archipelagos off the Alaskan-British Columbian coast, continuing down the coast to Central and South America. The alternative is the "interior route hypothesis", which assumes migration along an ice-free corridor between the Laurentide and Cordilleran ice sheets during the Last Glacial Maximum. The coastal migration hypothesis has been bolstered by findings such as the report that the sediments in the Port Eliza caves on Vancouver Island indicate the possibility of a survivable climate as far back 16 ka (16,000 years) in the area, while the continental ice sheets were nearing their maximum extent. Despite such research, the hypothesis is still subject to considerable debate. Carlson, Erlandson, and others have argued for a ...

Settlement Of The Americas
The settlement of the Americas began when Paleolithic hunter-gatherers entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the Last Glacial Maximum (26,000 to 19,000 years ago). These populations expanded south of the Laurentide Ice Sheet and spread rapidly southward, occupying both North and South America, by 12,000 to 14,000 years ago. The earliest populations in the Americas, before roughly 10,000 years ago, are known as Paleo-Indians. Indigenous peoples of the Americas have been linked to Siberian populations by linguistic factors, the distribution of blood types, and in genetic composition as reflected by molecular data, such as DNA. While there is general agreement that the Americas were first settled from Asia, the pattern of migration and the place(s) of origin in Eurasia of the peoples who migrated to the Americas remain unclear ...

Oral History
Oral history is the collection and study of historical information about individuals, families, important events, or everyday life using audiotapes, videotapes, or transcriptions of planned interviews. These interviews are conducted with people who participated in or observed past events and whose memories and perceptions of these are to be preserved as an aural record for future generations. Oral history strives to obtain information from different perspectives and most of these cannot be found in written sources. ''Oral history'' also refers to information gathered in this manner and to a written work (published or unpublished) based on such data, often preserved in archives and large libraries.oral history.

Prince Of Wales Island (Alaska)
Prince of Wales Island (Tlingit: ''Taan'') is one of the islands of the Alexander Archipelago in the Alaska Panhandle. It is the fourth-largest island in the United States (after Hawaii, Kodiak Island, and Puerto Rico) and the 97th-largest island in the world. Geography and ecology The island is long, wide and has an area of , about one-tenth the size of Ireland and slightly larger than the state of Delaware. Approximately 6,000 people live on the island. Craig is the largest community; founded as a saltery in the early 20th century, it has a population of 1,500. Some 900 people live in Klawock, a long-established village that grew with the fishing industry. Hollis was a boom and bust mining town from 1900 to about 1915. Abandoned, it was re-established as a logging camp in the 1950s. It now has a population of 100 and is the location of the ferry terminal. Mountain peaks, all but the tallest of which were buried by Pleistocene glaciation, reach over . Fjords, steep-si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
On Your Knees Cave
On Your Knees Cave (49-PET-408) is an archaeological site located in southeastern Alaska ( Prince of Wales Island). Human remains were found at the site in 1996 that dated between 9,730 ±60 and 9,880±50 radiocarbon YBP (Years Before Present) or a calendrical date of 10,300 YBP. In addition to human skeletal remains, stone tools and animal bones were discovered. DNA analyses performed on the human skeletal remains document the presence of mitochondrial haplogroup D which occurs widely in the Americas. Isotopic analysis indicated that the individual had a primarily marine based diet. Location On Your Knees Cave is located on the northern tip of Prince of Wales Island within the Tongass National Forest. Its location is approximately one kilometer from the coast and 125 meters above sea level. Originally, the entrance of the cave was obstructed by large rocks and soil that had fallen from the cliff above, and covered with vegetation. After the obstructions were cleared, the sma ...

Sea Level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. Current sea level rise is mainly caused by human-induced climate change. When temperatures rise, Glacier, mountain glaciers and the Ice sheet, polar ice caps melt, increasing the amount of water in water bodies. Because most of human settlem ...

Alexander Archipelago
The Alexander Archipelago (russian: Архипелаг Александра) is a long archipelago (group of islands) in North America lying off the southeastern coast of Alaska. It contains about 1,100 islands, the tops of submerged coastal mountains that rise steeply from the Pacific Ocean. Deep channels and fjords separate the islands and cut them off from the mainland. The islands shelter the northern part of the Inside Passage as it winds its way among them. The islands have irregular, steep coasts and dense evergreen and temperate rain forests; most are accessible only by boat or by aeroplane. The vast majority of the islands are part of the Tongass National Forest. In order of land area, the largest islands are Prince of Wales Island, Chichagof Island, Admiralty Island, Baranof Island, Revillagigedo Island, Kupreanof Island, Kuiu Island, Etolin Island, Dall Island, Wrangell Island, Mitkof Island, Zarembo Island, Kosciusko Island, Kruzof Island, Annette Island, Gravin ...

Wrangell Island
Wrangell Island (russian: Остров Врангеля) is an island in the Alexander Archipelago in the Alaska Panhandle of southeastern Alaska. It is long and wide. It has a land area of , making it the 29th largest island in the United States. Wrangell is separated from the mainland by the narrow Blake Channel. The first European to sight the island was James Johnstone, one of George Vancouver’s officers during his 1791-1795 expedition, in 1793. He only charted its east coast, not realizing it was an island. It was occupied in 1834 by the Russians. It is named after Ferdinand Wrangel, a Baltic German explorer in Russian service, and government official. From 1867 to 1877 it was a U.S. military post; later it became an outfitting point for hunters and explorers, and for miners using the Stikine River route to the Yukon. The island contains the city of Wrangell, Alaska. Wrangell Island is heavily forested and contains an abundance of wildlife. The only other commun ...
