Keyhole Sink
Keyhole Sink is a canyon in the shape of a keyhole near Williams, Arizona. The canyon is best known for its petroglyphs, which were created about 1,000 years ago by the ancient Cohonina people, and the seasonal waterfalls that flow into the canyon. Archaeology Keyhole Sink, formerly called Box Canyon, is a few miles east of Williams off Route 66 in Kaibab National Forest, and can be accessed on foot by a short, unpaved pathway known as Keyhole Sink Trail. Archaeological research suggests that not many people actually lived in Keyhole Sink, and that it was mainly used as a sort of sacred rest stop for hunters and as a place for clan initiations. Surrounding the site for a radius of fifteen miles are remnants of pit house foundations. The petroglyphs, which were carved into volcanic basalt, date from between 700 and 1100 CE. Design elements include snakes, lizards, deer, and amorphous images. The petroglyphs are considered to be heavily weathered, and in August 2010 vandals caused ...

Petroglyphs In Arizona
A petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. Outside North America, scholars often use terms such as "carving", "engraving", or other descriptions of the technique to refer to such images. Petroglyphs, estimated to be 20,000 years old are classified as protected monuments and have been added to the tentative list of UNESCO's World Heritage Sites. Petroglyphs are found worldwide, and are often associated with prehistoric peoples. The word comes from the Greek prefix , from meaning "stone", and meaning "carve", and was originally coined in French as . In scholarly texts, a ''petroglyph'' is a rock engraving, whereas a ''petrograph'' (or ''pictograph'') is a rock painting. In common usage, the words are sometimes used interchangeably. Both types of image belong to the wider and more general category of rock art or parietal art. Petroforms, or patterns and shapes made by many large ro ...

Archaeological Sites In Arizona
Archaeology or archeology is the 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. The discipline involves surveying, excavation, and eventually analysis of data collected, to learn more about the past. In broad scope, archaeology relies on cross-disciplinary research. 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 learn ...

Canyons And Gorges Of Arizona
A canyon (; archaic British English spelling: ''cañon''), gorge or chasm, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examples of mountain-type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sycamore Canyon (Yavapai County, Arizona)
Sycamore Canyon is the second largest canyon in the Arizona redrock country, after Oak Creek Canyon. The long scenic canyon reaches a maximum width of about . It is in North Central Arizona bordering and below the Mogollon Rim, and is located west and northwest of Sedona in Yavapai and Coconino counties. Description Sycamore Creek, a tributary of the Verde River, flows through the canyon. Sycamore Canyon enters the Verde River canyon north-northwest of Clarkdale. Located within three different U.S. National Forests, the Coconino, Kaibab, and Prescott National Forests, Sycamore Canyon is home to a variety of wildlife including black bear, deer, and mountain lion. Unlike the nearby and more heavily visited Oak Creek Canyon, much of Sycamore Canyon is protected by the Sycamore Canyon Wilderness, located at , and therefore roads and developed campgrounds are nonexistent. Hiking and horseback riding are the only ways to visit the canyon. The most popular access is via the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Pit House
A pit-house (or pit house, pithouse) is a house built in the ground and used for shelter. Besides providing shelter from the most extreme of weather conditions, this type of earth shelter may also be used to store food (just like a pantry, a larder, or a root cellar) and for cultural activities like the telling of stories, dancing, singing and celebrations. General dictionaries also describe a pit-house as a dugout, and it has similarities to a half-dugout. In archaeology, a pit-house is frequently called a sunken-featured building and occasionally (grub-) hut or grubhouse, after the German name ''Grubenhaus''. They are found in numerous cultures around the world, including the people of the Southwestern United States, the ancestral Pueblo, the ancient Fremont and Mogollon cultures, the Cherokee, the Inuit, the people of the Plateau, and archaic residents of Wyoming (Smith 2003) in North America; Archaic residents of the Lake Titicaca Basin (Craig 2005) in South America; An ...

Waterfall
A waterfall is any point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling onto softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls since prehistory, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century, they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Cohonina
The Cohonina peoples inhabited the north-western area of Arizona, to the west of the Grand Canyon in the United States. First identified in 1937 by Lyndon Hargrave, surveying pottery for the Museum of Northern Arizona, they are named for the Hopi term for the Yuman, Havasupai, and Walapai peoples who inhabited the area and are thought to be descended from the Cohonina. They in turn have lent their name to Coconino County, Arizona. They are thought to have lived between 500 and 1200, evolving alongside the Ancestral Puebloans (Anasazi) and enjoying a period of fertility, producing "significant" amounts of pottery, before worsening weather conditions – arid soils and rain erosion – forced them from their homelands. Several lines of evidence led to a theory that a climate change episode caused a severe drought A drought is a period of drier-than-normal conditions.Douville, H., K. Raghavan, J. Renwick, R.P.
