Shell Mound
A midden is an old dump for domestic waste. It may consist of animal bones, human excrement, botanical material, mollusc shells, potsherds, lithics (especially debitage), and other artifacts and ecofacts associated with past human occupation. These features provide a useful resource for archaeologists who wish to study the diets and habits of past societies. Middens with damp, anaerobic conditions can even preserve organic remains in deposits as the debris of daily life are tossed on the pile. Each individual toss will contribute a different mix of materials depending upon the activity associated with that particular toss. During the course of deposition sedimentary material is deposited as well. Different mechanisms, from wind and water to animal digs, create a matrix which can also be analysed to provide seasonal and climatic information. In some middens individual dumps of material can be discerned and analysed. Shells A shell midden or shell mound is an archae ...

Whaleback Shell Midden Gully - 20070722 07986
A whaleback was a type of cargo steamship of unusual design, with a hull that continuously curved above the waterline from vertical to horizontal. When fully loaded, only the rounded portion of the hull (the "whaleback" proper) could be seen above the waterline. With sides curved in towards the ends, it had a spoon bow and a very convex upper deck. It was formerly used on the Great Lakes of Canada and the United States, notably for carrying grain or ore. The sole surviving ship of the "whaleback" design is the , which is docked in Superior, Wisconsin, as a museum ship. The term developed in common usage in response to the ship's appearance when fully loaded. A total of 44 such vessels were constructed from 1887 to 1898. All but two were built initially as lake freighters for service on the Great Lakes. Six were built at Duluth, Minnesota; 33 were built at West Superior, Wisconsin; 2 at Brooklyn, New York; one at Everett, Washington; and one at Sunderland, England. A number ...

Japanese Prehistory
The first human inhabitants of the Japanese archipelago have been traced to the Paleolithic, around 38–39,000 years ago. The Jōmon period, named after its cord-marked pottery, was followed by the Yayoi period in the first millennium BC when new inventions were introduced from Asia. During this period, the first known written reference to Japan was recorded in the Chinese ''Book of Han'' in the first century AD. Around the 3rd century BC, the Yayoi people from the continent immigrated to the Japanese archipelago and introduced iron technology and agricultural civilization. Because they had an agricultural civilization, the population of the Yayoi began to grow rapidly and ultimately overwhelmed the Jōmon people, natives of the Japanese archipelago who were hunter-gatherers. Between the fourth and ninth centuries, Japan's many kingdoms and tribes gradually came to be unified under a centralized government, nominally controlled by the Emperor of Japan. The imperial dynasty es ...

Jōmon Pottery
The is a type of ancient earthenware pottery which was made during the Jōmon period in Japan. The term "Jōmon" () means "rope-patterned" in Japanese, describing the patterns that are pressed into the clay. Outline Oldest pottery in Japan The pottery vessels crafted in Ancient Japan during the Jōmon period are generally accepted to be the oldest pottery in Japan and among the oldest in the world. Dating Odai Yamamoto I site in Aomori Prefecture currently has the oldest pottery in Japan. Excavations in 1998 uncovered forty-six earthenware fragments which have been dated as early as 14,500 BCE (ca 16,500 BP); this places them among the earliest pottery currently known. This appears to be plain, undecorated pottery. Such a date puts the development of pottery before the warming at the end of the Pleistocene. 'Linear-relief' pottery was also found at Fukui cave Layer III dating to 13,850–12,250 BCE. This site is located in Nagasaki Prefecture, Kyushu. Both line ...

Edward Sylvester Morse
Edward Sylvester Morse (June 18, 1838 – December 20, 1925) was an American zoologist, archaeologist, and orientalist. He is considered the "Father of Japanese archaeology." Early life Morse was born in Portland, Maine to Jonathan Kimball Morse and Jane Seymour (Becket) Morse. His father was a Congregationalist deacon who held strict Calvinist beliefs. His mother, who did not share her husband's religious beliefs, encouraged her son's interest in the sciences. An unruly student, Morse was expelled from all but one of the schools he attended in his youth — the Portland village school, the academy at Conway, New Hampshire, in 1851, and Bridgton Academy in 1854 (for carving on desks). He also attended Gould Academy in Bethel, Maine. At Gould Academy, Morse came under the influence of Dr. Nathaniel True who encouraged Morse to pursue his interest in the study of nature. He preferred to explore the Atlantic coast in search of shells and snails, or go to the field to st ...

Alkaline
In chemistry, an alkali (; from the Arabic word , ) is a basic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases. Etymology The word ''alkali'' is derived from Arabic ''al qalīy'' (or ''alkali''), meaning (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly of potassium carbonate, was mildly basic. After heating this substance with calcium hydroxide (''slaked lime''), a far more strongly basic substance known as ''caustic ...

Calcium Carbonate
Calcium carbonate is a chemical compound with the chemical formula . It is a common substance found in Rock (geology), rocks as the minerals calcite and aragonite, most notably in chalk and limestone, eggshells, gastropod shells, shellfish skeletons and pearls. Materials containing much calcium carbonate or resembling it are described as calcareous. Calcium carbonate is the active ingredient in agricultural lime and is produced when calcium ions in hard water react with carbonate ions to form limescale. It has medical use as a calcium supplement or as an antacid, but excessive consumption can be hazardous and cause hypercalcemia and digestive issues. Chemistry Calcium carbonate shares the typical properties of other carbonates. Notably, it: *reacts with acids, releasing carbonic acid which quickly disintegrates into carbon dioxide and water: : *releases carbon dioxide upon heating, called a thermal decomposition reaction, or calcination (to above 840 °C in the case of ), t ...

Stone Tools
Stone tools have been used throughout human history but are most closely associated with prehistoric cultures and in particular those of the Stone Age. Stone tools may be made of either ground stone or knapped stone, the latter fashioned by a craftsman called a flintknapper. Stone has been used to make a wide variety of tools throughout history, including arrowheads, spearheads, hand axes, and querns. Knapped stone tools are nearly ubiquitous in pre-metal-using societies because they are easily manufactured, the tool stone raw material is usually plentiful, and they are easy to transport and sharpen. The study of stone tools is a cornerstone of prehistoric archaeology because they are essentially indestructible and therefore a ubiquitous component of the archaeological record. Ethnoarchaeology is used to further the understanding and cultural implications of stone tool use and manufacture. Knapped stone tools are made from cryptocrystalline materials such as chert, flint ...
