Aleutian Tradition
The Aleutian Tradition began around 2500 BC and ended in AD 1800. Aleutian artifacts are made out of chopped stone, unlike the more common slate tools. Objects were traditionally made using a concept called core and flake that uses bifacially carved projectile points. The Aleutian people lived in semi-subterranean winter houses made from driftwood, whale bone, and peat. They used kayaks, atlatl A spear-thrower, spear-throwing lever or ''atlatl'' (pronounced or ; Nahuatl ''ahtlatl'' ) is a tool that uses leverage to achieve greater velocity in dart or javelin-throwing, and includes a bearing surface which allows the user to store ene ...s and harpoons to kill sea mammals for sustenance. Around AD 1150 Aleutian houses increased considerably in size. Food was stored in special chambers inside the house and weaponry was becoming more common around these sites. The sustenance pattern changed from relying on sea mammals to eating mostly salmon. Long-distance trade also start ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aleut People
The Aleuts ( ; russian: Алеуты, Aleuty) are the indigenous people of the Aleutian Islands, which are located between the North Pacific Ocean and the Bering Sea. Both the Aleut people and the islands are politically divided between the US state of Alaska and the Russian administrative division of Kamchatka Krai. Etymology In the Aleut language they are known by the endonyms Unangan (eastern dialect) and Unangas (western dialect), both of which mean "people". The Russian term "Aleut" was a general term used for both the native population of the Aleutian Islands and their neighbors to the east in the Kodiak Archipelago, who were also referred to as "Pacific Eskimos". Language Aleut people speak Unangam Tunuu, the Aleut language, as well as English and Russian in the United States and Russia respectively. An estimated 150 people in the United States and five people in Russia speak Aleut. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock (geology)
In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its Chemical compound, chemical composition, and the way in which it is formed. Rocks form the Earth's outer solid layer, the Earth's crust, crust, and most of its interior, except for the liquid Earth's outer core, outer core and pockets of magma in the asthenosphere. The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy. It may be limited to rocks found on Earth, or it may include planetary geology that studies the rocks of other celestial objects. Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed. Sedimentary rocks are formed by diagenesis and lithification of sediments, which in turn are formed by the weathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slate
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called " slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates will display a property called fissility, forming smooth flat sheets of stone which have long been used for roofing, floor tiles, and other purposes. Slate is frequently grey in color, especially when seen, en masse, covering roofs. However, slate occurs in a variety of colors even from a single locality; f ...

Kayak
A kayak is a small, narrow watercraft which is typically propelled by means of a double-bladed paddle. The word kayak originates from the Greenlandic word '' qajaq'' (). The traditional kayak has a covered deck and one or more cockpits, each seating one paddler. The cockpit is sometimes covered by a spray deck that prevents the entry of water from waves or spray, differentiating the craft from a canoe. The spray deck makes it possible for suitably skilled kayakers to roll the kayak: that is, to capsize and right it without it filling with water or ejecting the paddler. ] Some modern boats vary considerably from a traditional design but still claim the title "kayak", for instance in eliminating the cockpit by seating the paddler on top of the boat ("sit-on-top" kayaks); having inflated air chambers surrounding the boat; replacing the single hull with twin hulls; and replacing paddles with other human-powered propulsion methods, such as foot-powered rotational propellers an ...

Atlatl
A spear-thrower, spear-throwing lever or ''atlatl'' (pronounced or ; Nahuatl ''ahtlatl'' ) is a tool that uses leverage to achieve greater velocity in dart or javelin-throwing, and includes a bearing surface which allows the user to store energy during the throw. It may consist of a shaft with a cup or a spur at the end that supports and propels the butt of the spear. It's usually about as long as the user's arm or forearm. The user holds the spear-thrower in one hand, gripping near the end farthest from the cup. The user puts the butt end of the spear, or dart, in the cup, or grabs the spur with the end of the spear. The spear is much longer than the thrower. The user holds the spear parallel to the spear-thrower and going in the other direction. The user can hold the spear, with the index and thumb, with the same hand as the thrower, with the other fingers. The user reaches back with the spear pointed at the target. Then they make an overhand throwing motion with the thrower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harpoons
A harpoon is a long spear-like instrument and tool used in fishing, whaling, sealing, and other marine hunting to catch and injure large fish or marine mammals such as seals and whales. It accomplishes this task by impaling the target animal and securing it with barb or toggling claws, allowing the fishermen to use a rope or chain attached to the projectile to catch the animal. A harpoon can also be used as a weapon. Certain harpoons are made with different builds to perform better with the type of target being aimed at. For example, the Inuit have short, fixed foreshaft harpoons for hunting seals at their breathing holes while loose shafted ones are made for attaching to the game thrown at. History In the 1990s, harpoon points, known as the Semliki harpoons or the Katanda harpoons, were found in the Katanda region in Zaire (called the Democratic Republic of the Congo today). As the earliest known harpoons, these weapons were made and used 90,000 years ago, most likely to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disturbance (archaeology)
A disturbance is any change to an archaeological site due to events which occurred after the site was laid down. Disturbances may be caused by natural events or human activity, and may result in loss of archaeological value. In some cases, it can be difficult to distinguish between features caused by human activity in the period of interest and features caused by later human activity, or by natural processes. Causes Natural causes The soil scientist Francis D. Hole identified nine natural processes resulting in soil disturbance, including the movements of animals and plants (especially burrowing, root growth and treefalls), freezing and thawing, movement under gravity (including earthflow and rockslides), swelling and shrinking of clays, the actions of wind and water, the growth and dissolution of salt crystals, and movement caused by earthquakes. Different sites are subject to different degrees, combinations, and interactions of these processes, and archaeologists wor ...
