Bedrock Mortar
A bedrock mortar (BRM) is an anthropogenic circular depression in a rock outcrop or naturally occurring slab, used by people in the past for grinding of grain, acorns or other food products. There are often a cluster of a considerable number of such holes in proximity indicating that people gathered in groups to conduct food grinding in prehistoric cultures. Correspondingly the alternative name gossip stone is sometimes applied, indicating the social context of the food grinding activity. Typical dimensions of the circular indentations are approximately 12 centimeters in diameter by 10 centimeters deep, although a considerable range of depths of the cavities have been documented . The bedrock mortar has been identified in a number of world regions, but has been particularly intensely documented in the Americas. An alternative term for the bedrock mortar site is bedrock milling station. Bedrock metate A bedrock mortar should not be confused with a bedrock metate, which is a fla ...

Bedrock Mortar In A Rock Shelter On The Upper Cumberland Plateau
In geology, bedrock is solid rock that lies under loose material (regolith) within the crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysical methods is an important task in most civil engineering projects. Superficial deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave it susceptible to erosion. Bedrock may also experience subsurface ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maidu People
The Maidu are a Native American people of northern California. They reside in the central Sierra Nevada, in the watershed area of the Feather and American rivers. They also reside in Humbug Valley. In Maiduan languages, ''Maidu'' means "man." Local division The Maidu people are geographically dispersed into many subgroups or bands who live among and identify with separate valleys, foothills, and mountains in Northeastern Central California. There are three subcategories of Maidu: * The Nisenan or Southern Maidu occupied the whole of the American, Bear, and Yuba River drainages. They live in lands that were previously home to the Martis. * The Northeastern or Mountain Maidu, also known as Yamani Maidu, lived on the upper North and Middle forks of the Feather River. * The Konkow (Koyom'kawi/Concow) occupied a valley between present-day Cherokee, and Pulga, along the north fork of the Feather River and its tributaries.

Mount Carmel
Mount Carmel ( he, הַר הַכַּרְמֶל, Har haKarmel; ar, جبل الكرمل, Jabal al-Karmil), also known in Arabic as Mount Mar Elias ( ar, link=no, جبل مار إلياس, Jabal Mār Ilyās, lit=Mount Saint Elias/Elijah), is a coastal mountain range in northern Israel stretching from the Mediterranean Sea towards the southeast. The range is a UNESCO biosphere reserve. A number of towns are situated there, most notably the city of Haifa, Israel's third largest city, located on the northern and western slopes. Etymology The word ''karmel'' means "garden-land" and is of uncertain origin. It is either a compound of ''kerem'' and ''el'', meaning "vineyard of El (deity), God" or a clipping of ''kar male,'' meaning "full kernel." Martin Jan Mulder suggested a third etymology, that of ''kerem + l'' with the lamed a wiktionary:sufformative, sufformative, but this is considered unlikely as evidence for the existence of a lamed sufformative is weak.

Natufian Culture
The Natufian culture () is a Late Epipaleolithic archaeological culture of the Levant, dating to around 15,000 to 11,500 years ago. The culture was unusual in that it supported a sedentary or semi-sedentary population even before the introduction of agriculture. The Natufian communities may be the ancestors of the builders of the first Neolithic settlements of the region, which may have been the earliest in the world. Some evidence suggests deliberate cultivation of cereals, specifically rye, by the Natufian culture, at Tell Abu Hureyra, the site of earliest evidence of agriculture in the world. The world's oldest known evidence of the production of bread-like foodstuff has been found at Shubayqa 1, a 14,400-year-old site in Jordan's northeastern desert, 4,000 years before the emergence of agriculture in Southwest Asia In addition, the oldest known evidence of possible beer-brewing, dating to approximately 13,000 BP, was found at the Raqefet Cave in Mount Carmel near Haifa in I ...

Cumberland Plateau
The Cumberland Plateau is the southern part of the Appalachian Plateau in the Appalachian Mountains of the United States. It includes much of eastern Kentucky and Tennessee, and portions of northern Alabama and northwest Georgia.

Two major rivers share the names of the plateaus, with the Allegheny River rising in the Allegheny Plateau and the Cumberland River rising in the Cumberland Plateau in Harlan County, Kentucky. Geography The Cumberland Plateau is a deeply dissected plateau, with topographic relief commonly of about , and frequent sandstone outcroppings and bluffs.
