Fire-cracked Rock
In archaeology, fire-cracked rock (FCR) or fire-affected rock (FAR), is rock of any type that has been altered and split as the result of deliberate heating. It is a feature of many archaeological sites. In many cases, fire-cracked rock results when stones were used to line hearths and earth ovens or were heated to provide a longer-lasting heat-source (similar to a modern hot water bottle). In other cases, fire-cracked rock results from stone being used to heat or boil water. The stones were heated and dropped directly into water held in containers made of skin or baskets and pottery. This use has led fire-cracked rocks to be called "pot-boilers" in Britain. Central Texas in the United States in particular is well-known archaeologically for its burned rock middens, which are piles of fire-cracked rock—often exceeding several tons of material. These represent the remains of earth ovens used in cooking sotol bulbs and other plants during prehistoric times. In Britain, these featur ...

Archaeology
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the adven ...

Archaeological Site
An archaeological site is a place (or group of physical sites) in which evidence of past activity is preserved (either prehistoric or historic or contemporary), and which has been, or may be, investigated using the discipline of archaeology and represents a part of the archaeological record. Sites may range from those with few or no remains visible above ground, to buildings and other structures still in use. Beyond this, the definition and geographical extent of a "site" can vary widely, depending on the period studied and the theoretical approach of the archaeologist. Geographical extent It is almost invariably difficult to delimit a site. It is sometimes taken to indicate a settlement of some sort although the archaeologist must also define the limits of human activity around the settlement. Any episode of deposition such as a hoard or burial can form a site as well. Development-led archaeology undertaken as cultural resources management has the disadvantage (or the ben ...

Hearth
A hearth () is the place in a home where a fire is or was traditionally kept for home heating and for cooking, usually constituted by at least a horizontal hearthstone and often enclosed to varying degrees by any combination of reredos (a low, partial wall behind a hearth), fireplace, oven, smoke hood, or chimney. Hearths are usually composed of masonry such as brick or stone. For centuries, the hearth was such an integral part of a home, usually its central and most important feature, that the concept has been generalized to refer to a homeplace or household, as in the terms "hearth and home" and "keep the home fires burning". In the modern era, since the advent of central heating, hearths are usually less central to most people's daily life because the heating of the home is instead done by a furnace or a heating stove, and cooking is instead done with a kitchen stove/range (combination cooktop and oven) alongside other home appliances; thus many homes built in the 20t ...

Earth Oven
An earth oven, ground oven or cooking pit is one of the simplest and most ancient cooking structures. At its most basic, an earth oven is a pit in the ground used to trap heat and bake, smoke, or steam food. Earth ovens have been used in many places and cultures in the past, and the presence of such cooking pits is a key sign of human settlement often sought by archaeologists. Earth ovens remain a common tool for cooking large quantities of food where no equipment is available. They have been used in various civilizations around the world and are still commonly found in the Pacific region to date. To bake food, the fire is built, then allowed to burn down to a smoulder. The food is then placed in the oven and covered. This covered area can be used to bake bread or other various items. Steaming food in an earth oven covers a similar process. Fire-heated rocks are put into a pit and are covered with green vegetation to add moisture and large quantities of food. More green vegetati ...

Pottery
Pottery is the process and the products of forming vessels and other objects with clay and other ceramic materials, which are fired at high temperatures to give them a hard and durable form. Major types include earthenware, stoneware and porcelain. The place where such wares are made by a ''potter'' is also called a ''pottery'' (plural "potteries"). The definition of ''pottery'', used by the ASTM International, is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products". In art history and archaeology, especially of ancient and prehistoric periods, "pottery" often means vessels only, and sculpted figurines of the same material are called "terracottas". Pottery is one of the oldest human inventions, originating before the Neolithic period, with ceramic objects like the Gravettian culture Venus of Dolní Věstonice figurine discovered in the Czech Republic dating back to 29,000–25,000 BC, and pottery vessels that were ...

Midden
A midden (also kitchen midden or shell heap) is an old dump for domestic waste which may consist of animal bone, 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 mi ...

Sotol
Sotol is a distilled spirit from the Chihuahuan desert northern Mexico, western Texas sourced from the family of Asparagaceae; the genus Dasylirion and several species, most commonly: ''Dasylirion wheeleri'', Dasylirion durangense, ''Dasylirion cedrosanum'', and ''Dasylirion leiophyllum'', less commonly with Dasylirion texanum and Dasylirion lucidum (commonly known as Desert Spoon or, in Spanish, ''sotol, sereque, cucharilla, or palmilla''), a plant that grows in the Chihuahua desert of northern Mexico, New Mexico, Arizona, and west and central Texas. Sotol liquor is a Mexican drink that is known as the state spirit of Chihuahua, Durango and Coahuila. Sotol has its own appellation of origin since 2002, and may be produced only in Chihuahua, Coahuila and Durango. There are dozens of commercial examples available. Production of sotol spirits exists outside the Sotol Denomination of Origin in several regions such as Sonora where it is known as Palmilla, Oaxaca (Cucharillo), and t ...

Burnt Mound
A burnt mound is an archaeological feature consisting of a mound of shattered stones and charcoal, normally with an adjacent hearth and trough. The trough could be rock-cut, wood-lined or clay-lined to ensure it was watertight. Radiocarbon dates vary quite widely, the earliest being late Neolithic, with clusters of dates between 1900 and 1500 BC and 1200–800 BC, with some outliers in the Iron Age. There are also some dates that go into the Early Middle Ages. The technology used at burnt mounds has much greater antiquity and is found from the Palaeolithic onwards. Description and creation The shattered rock fragments are thought to be the remains of stones heated in fires, which were used to heat water. The shattering of the rock appears to have been the result of thermal shock when the heated stones were dropped into liquid, normally believed to be water. The mound is assumed to result from the periodic clearing out of the trough, with the stone fragments and charcoal be ...
