Two Nuns
Two Nuns are summits in Coconino County, Arizona, United States. Description Two Nuns is located south of Sedona and one-half mile (0.8 km) east of Chapel of the Holy Cross, on land managed by Coconino National Forest. Precipitation runoff from this landform drains to Oak Creek which is part of the Verde River watershed. Topographic relief is significant as the summit rises above Little Horse Park in 0.2 mile (0.32 km). Two Nuns is composed of reddish sandstone of the Schnebly Hill Formation. The landform's Two Nuns toponym has not been officially adopted by the United States Board on Geographic Names, so various names exist such as "The Nuns", "Twin Nuns", "Christianity Spire", "Streaker Spire" and "The Four Nuns." North Nun North Nun is also known as Christianity Spire. It is sometimes also called Beckey's Spire for Fred Beckey who made the first ascent in 1970. The rock-climbing route called ''Blast from the Past'' was first climbed by Tom Isaac and Jeff Bowma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coconino National Forest
The Coconino National Forest is a 1.856-million acre (751,000 ha) United States National Forest located in northern Arizona in the vicinity of Flagstaff, with elevations ranging from 2,600 feet to the highest point in Arizona at 12,633 feet (Humphrey's Peak). Originally established in 1898 as the "San Francisco Mountains National Forest Reserve", the area was designated a U.S. National Forest by Pres. Theodore Roosevelt on July 2, 1908, when the San Francisco Mountains National Forest Reserve was merged with lands from other surrounding forest reserves to create the Coconino National Forest. Today, the Coconino National Forest contains diverse landscapes, including deserts, ponderosa pine forests, flatlands, mesas, alpine tundra, and ancient volcanic peaks. The forest surrounds the towns of Sedona and Flagstaff and borders four other national forests; the Kaibab National Forest to the west and northwest, the Prescott National Forest to the southwest, the Tonto National Forest ...

Verde River
The Verde River ( Yavapai: Haka'he:la) is a major tributary of the Salt River in the U.S. state of Arizona. It is about long and carries a mean flow of at its mouth. It is one of the largest perennial streams in Arizona. Description The river begins below the dam at Sullivan Lake, fed by Big Chino Wash and Williamson Valley Wash in Yavapai County. The Verde flows freely for through private, state, tribal and United States Forest Service lands, specifically the Prescott National Forest, Coconino National Forest and Tonto National Forest, before encountering the first of two dams that make Horseshoe Lake and Bartlett Lake. The cities of Camp Verde, Clarkdale and Cottonwood are the main population centers along the river. The Verde River and the Salt River converge on the Salt River Pima-Maricopa Indian Community. The Salt River flows into the Gila River west of Phoenix. In 1984, the United States Congress designated of the Verde River as Wild and Scenic through the ...

Buttes Of Arizona
In geomorphology, a butte ( ) is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller landforms than mesas, plateaus, and tablelands. The word ''butte'' comes from the French word , meaning 'knoll' (of any size); its use is prevalent in the Western United States, including the southwest where (Spanish for 'table') is used for the larger landform. Due to their distinctive shapes, buttes are frequently landmarks in plains and mountainous areas. To differentiate the two landforms, geographers use the rule of thumb that a mesa has a top that is wider than its height, while a butte has a top that is narrower than its height. Formation Buttes form by weathering and erosion when hard caprock overlies a layer of less resistant rock that is eventually worn away. The harder rock on top of the butte resists erosion. The caprock provides protection for the less resistant rock below from wind abrasion which leaves it standing isolated. As ...

Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSh'' and ''BSk'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as they usually cannot support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): * ...

Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...

First Ascent
In mountaineering and climbing, a first ascent (abbreviated to FA in climbing guidebook, guide books), is the first successful documented climb to the top of a mountain or the top of a particular climbing route. Early 20th-century mountaineers and climbers focused on reaching the tops of iconic mountains (e.g. the eight-thousanders) and climbing routes (e.g. the great north faces of the Alps) by whatever means possible, often using considerable amounts of aid climbing, and/or with large expedition style support teams that laid "siege" to the climb. As all the key tops were summited, the manner in which each top was reached became important, particularly the ability to complete the ascent without artificial aid, which is called free climbing. In free climbing, the term first free ascent (abbreviated FFA) is used where a mountain or climbing route is ascended without any artificial aid (devices for climbing protection, protection in the event of a fall could be used as long as the ...

Schnebly Hill Formation
The Schnebly Hill Formation is a section of red bed deposits found at the Colorado Plateau, near Sedona, Arizona. It is a dark red sandstone, from to thick. It lies between Coconino Sandstone and the older Hermit Formation. It is near the Supai Group. The source of the name "Schnebly" is Sedona Schnebly, after whom the city of Sedona, Arizona, was named. Geology The formation traces to the Permian Age. The formation is the most prominent layer of the red rocks of the Sedona area due the presence of hematite – iron-oxide (rust) – giving the sandstone a red color. The Schnebly Hill Sandstone formation comprises three sections: * the Bell Rock member, * the Fort Apache member, and * the Sycamore Pass member. See also Sedona-area rocks * Bell Rock * Capitol Butte * Cathedral Rock * Courthouse Butte * Red Rock State Park * Slide Rock State Park * Two Nuns Local geology * Colorado Plateau * Mogollon Rim * Supai Group Local interest * Cottonwood, ...

Topographic Relief
Terrain (), alternatively relief or topographical relief, is the dimension and shape of a given surface of land. In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns. Bathymetry is the study of underwater relief, while hypsometry studies terrain relative to sea level. Importance The understanding of terrain is critical for many reasons: * The terrain of a region largely determines its suitability for human settlement: flatter alluvial plains tend to have better farming soils than steeper, rockier uplands. * In terms of environmental quality, agriculture, hydrology and other interdisciplinary sciences; understanding the terrain of an area assists the understanding of watershed boundaries, drainage characteristics, drainage systems, groundwater systems, water ...

Oak Creek (Arizona)
Oak Creek Canyon is a river gorge located in northern Arizona between the cities of Flagstaff and Sedona. The canyon is often described as a smaller cousin of the Grand Canyon because of its scenic beauty. State Route 89A enters the canyon on its north end via a series of hairpin turns before traversing the bottom of the canyon for about until the highway enters the town of Sedona. Geography Oak Creek Canyon is about long, ranging in width from . The depth of the canyon ranges from . However, due to the faulting that played a major role in its formation, the west rim of the canyon is higher than the east rim. The average elevation of the west rim is while the east rim elevation is . Oak Creek Oak Creek, a tributary of the Verde River, flows along the bottom of the canyon, and is one of the few perennial streams in the high desert region of northern Arizona. Oak Creek is largely responsible for carving the modern Oak Creek Canyon, although movement along the Oak Creek Fau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
