Bradshaw Mountains
The Bradshaw Mountains ( yuf-x-yav, Wi:kañacha, "rough, black range of rocks") are a mountain range in central Arizona, United States, named for brothers Isaac and William D. Bradshaw after their deaths, having been formerly known in English as the Silver Mountain Range. History The first known settlements in the Bradshaws were a group of Yavapai people, called the Kwevkapaya who built forts and mined copper from around AD 1100 to 1600. The Walker party found gold, and within a few years, the Bradshaws were filling up with settlers mining for gold, silver, and copper. In the early part of the 20th century, most of the towns that had sprung up were little more than ghost towns. Geography Located approximately 5 miles (8 km) south of Prescott, Arizona, between the Agua Fria River on the east, and the Hassayampa River on the west, the range is 40 miles (64 km) long, and almost 25 miles (40 km) wide.

Yavapai County, Arizona
Yavapai County is near the center of the U.S. state of Arizona. As of the 2020 United States census, 2020 census, its population was 236,209, making it the fourth-most populous county in Arizona. The county seat is Prescott, Arizona, Prescott. Yavapai County comprises the Prescott, AZ Metropolitan statistical area, Metropolitan Statistical Area as well as the northern portions of Peoria, Arizona, Peoria and Wickenburg, Arizona, Wickenburg, the balance of which are in the Phoenix Metropolitan Area. History Yavapai County was one of the four original Arizona counties created by the 1st Arizona Territorial Legislature. The county territory was defined as being east of longitude 113° 20' and north of the Gila River. Soon thereafter, the counties of Apache County, Arizona, Apache, Coconino County, Arizona, Coconino, Maricopa County, Arizona, Maricopa, and Navajo County, Arizona, Navajo were carved from the original Yavapai County. Yavapai County's present boundaries were establish ...

Mount Union (Arizona)
Mount Union is a mountain located in the Prescott National Forest in central Yavapai County, Arizona. The mountain's summit is the highest point of the Bradshaw Mountains, and of Yavapai County. Mount Union is flanked to the northeast by Mount Davis. A lookout tower built by the CCC is on top of Mount Union, and exceeds 8,000 foot elevation. A service road for the communication towers allows easy access to the summit of Mount Union. However, the road goes through private property and is closed to motorized vehicles. Walk to the top for great 360 degree views. See also * List of mountains in Arizona The following is a list of the mountains and hills of Arizona, ordered by height.

Chaparral
Chaparral ( ) is a shrubland plant community and geographical feature found primarily in the U.S. state of California, in southern Oregon, and in the northern portion of the Baja California Peninsula in Mexico. It is shaped by a Mediterranean climate (mild wet winters and hot dry summers) and infrequent, high-intensity crown fires. Chaparral features summer-drought-tolerant plants with hard sclerophyllous evergreen leaves, as contrasted with the associated soft-leaved, drought-deciduous, scrub community of coastal sage scrub, found often on drier, southern facing slopes within the chaparral biome. Three other closely related chaparral shrubland systems occur in central Arizona, western Texas, and along the eastern side of central Mexico's mountain chains (mexical), all having summer rains in contrast to the Mediterranean climate of other chaparral formations. Chaparral comprises 9% of California's wildland vegetation and contains 20% of its plant species. The name comes from th ...

Schist
Schist ( ) is a medium-grained metamorphic rock showing pronounced schistosity. This means that the rock is composed of mineral grains easily seen with a low-power hand lens, oriented in such a way that the rock is easily split into thin flakes or plates. This texture (geology), texture reflects a high content of platy minerals, such as micas, talc, chlorite group, chlorite, or graphite. These are often interleaved with more granular minerals, such as feldspar or quartz. Schist typically forms during regional metamorphism accompanying the process of mountain building (orogeny) and usually reflects a medium Metamorphism#Metamorphic grades, grade of metamorphism. Schist can form from many different kinds of rocks, including sedimentary rocks such as mudstones and igneous rocks such as tuffs. Schist metamorphosed from mudstone is particularly common and is often very rich in mica (a ''mica schist''). Where the type of the original rock (the protolith) is discernible, the schist is us ...

Gneiss
Gneiss ( ) is a common and widely distributed type of metamorphic rock. It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks. Gneiss forms at higher temperatures and pressures than schist. Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands and without a distinct cleavage. Gneisses are common in the ancient crust of continental shields. Some of the oldest rocks on Earth are gneisses, such as the Acasta Gneiss. Description Orthogneiss from the Czech Republic In traditional English and North American usage, a gneiss is a coarse-grained metamorphic rock showing compositional banding (gneissic banding) but poorly developed schistosity and indistinct cleavage. In other words, it is a metamorphic rock composed of mineral grains easily seen with the unaided eye, which form obvious compositional layers, but which has only a weak tendency to fracture ...

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards. The Precambrian fossil ...

Towers Mountain
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean language, ...
