Natural Bridges National Monument
Natural Bridges National Monument is a U.S. National Monument located about northwest of the Four Corners boundary of southeast Utah, in the western United States, at the junction of White Canyon and Armstrong Canyon, part of the Colorado River drainage. It features the thirteenth largest natural bridge in the world, carved from the white Permian sandstone of the Cedar Mesa Formation that gives White Canyon its name. The three bridges in the park are named ''Kachina'', ''Owachomo'', and ''Sipapu'' (the largest), which are all Hopi names. A natural bridge is formed through erosion by water flowing in the stream bed of the canyon. During periods of flash floods, particularly, the stream undercuts the walls of rock that separate the meanders (or "goosenecks") of the stream until the rock wall within the meander is undercut and the meander is cut off and the new stream bed then flows underneath the bridge. Eventually, as erosion and gravity enlarge the bridge's opening, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Natural Bridge
A natural arch, natural bridge, or (less commonly) rock arch is a natural landform where an arch has formed with an opening underneath. Natural arches commonly form where inland cliffs, coastal cliffs, fins or stacks are subject to erosion from the sea, rivers or weathering ( subaerial processes). Most natural arches are formed from narrow fins and sea stacks composed of sandstone or limestone with steep, often vertical, cliff faces. The formations become narrower due to erosion over geologic time scales. The softer rock stratum erodes away creating rock shelters, or alcoves, on opposite sides of the formation beneath the relatively harder stratum, or caprock, above it. The alcoves erode further into the formation eventually meeting underneath the harder caprock layer, thus creating an arch. The erosional processes exploit weaknesses in the softer rock layers making cracks larger and removing material more quickly than the caprock; however, the caprock itself continues to erod ...

Night Sky
The night sky is the nighttime appearance of celestial objects like stars, planets, and the Moon, which are visible in a clear sky between sunset and sunrise, when the Sun is below the horizon. Natural light sources in a night sky include moonlight, starlight, and airglow, depending on location and timing. Aurorae light up the skies above the polar circles. Occasionally, a large coronal mass ejection from the Sun or simply high levels of solar wind may extend the phenomenon toward the Equator. The night sky and studies of it have a historical place in both ancient and modern cultures. In the past, for instance, farmers have used the status of the night sky as a calendar to determine when to plant crops. Many cultures have drawn constellations between stars in the sky, using them in association with legends and mythology about their deities. The anciently developed belief of astrology is generally based on the belief that relationships between heavenly bodies infl ...

International Dark-Sky Association
The International Dark-Sky Association (IDA) is a United States-based non-profit organization incorporated in 1988 by founders David Crawford, a professional astronomer, and Tim Hunter, a physician/amateur astronomer. The mission of the IDA is "to preserve and protect the night time environment and our heritage of dark skies through quality outdoor lighting." Light pollution is the result of outdoor lighting that is not properly shielded, allowing light shine into the eyes and night sky. Direct light that shines into the eyes is called glare, and light directed into the night sky above the horizon causes skyglow. Lighting can also cause light trespass when it enters areas where unwanted (e.g. a neighbor's yard and windows). IDA was the first organization in the dark-sky movement, and is currently the largest. Principal approach IDA's principal approach is to raise awareness about the value of dark, star-filled night skies and encourage their protection and restoration through e ...

Natural Bridges National Monument Solar Power System
Natural Bridges National Monument Solar Power System is an experimental electrical power plant at the Natural Bridges National Monument in the southeastern portion of the U.S. state of Utah. It consists of 256,812 solar cells arranged in 12 rows, each measuring long. Direct current energy from the array is converted to alternating current at an equipment building, then supplied to the park's staff buildings and visitor center. Excess energy is stored in a bank of batteries that is used on cloudy days. The system is controlled by computers and creates fewer emissions than the diesel generators that it replaced. When it was dedicated in June 1980 by the Utah Governor, it was the world's largest solar plant at 100 kW. The solar power station was later downsized to 50 kW and supplemented with a diesel generator backup system which allowed the solar array to operate more efficiently. History The electrical power plant, located in Natural Bridges National Monument, is a jo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sipapu Bridge 2
A (a Hopi word) was a small hole or indentation in the floor of a (pithouse). Kivas were used by the Ancestral Puebloans and continue to be used by modern-day Puebloans. The symbolizes the portal through which their ancient ancestors first emerged to enter the present world. Hopi mythology (and similar traditions in other Pueblo cultures such as the Zuni and Acoma Acoma may refer to: * ''Acoma'' (beetle), a scarab beetle genus of subfamily Melolonthinae * Acoma Pueblo, a Native American pueblo * Acoma, Nevada, a ghost town * Acoma Township, McLeod County, Minnesota, US * , more than one ship of the US Navy ...) states that this is the hole from which the first peoples of this world entered. As they stepped outside of the , they changed from lizard-like beings into human form. It is from this point that the "First Peoples" of the Earth began to divide and separate, becoming tribes. The original sipapu is said to be located in the Grand Canyon. References Citations W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptobiotic Soil
Biological soil crusts are communities of living organisms on the soil surface in arid and semi-arid ecosystems. They are found throughout the world with varying species composition and cover depending on topography, soil characteristics, climate, plant community, microhabitats, and disturbance regimes. Biological soil crusts perform important ecological roles including carbon fixation, nitrogen fixation and soil stabilization; they alter soil albedo and water relations and affect germination and nutrient levels in vascular plants. They can be damaged by fire, recreational activity, grazing and other disturbances and can require long time periods to recover composition and function. Biological soil crusts are also known as ''biocrusts'' or as ''cryptogamic'', ''microbiotic'', ''microphytic'', or ''cryptobiotic'' soils. Natural history Biology and composition Biological soil crusts are most often composed of fungi, lichens, cyanobacteria, bryophytes, and algae in varying proportions ...

Colorado Plateau
The Colorado Plateau, also known as the Colorado Plateau Province, is a physiographic and desert region of the Intermontane Plateaus, roughly centered on the Four Corners region of the southwestern United States. This province covers an area of 336,700 km2 (130,000 mi2) within western Colorado, northwestern New Mexico, southern and eastern Utah, northern Arizona, and a tiny fraction in the extreme southeast of Nevada. About 90% of the area is drained by the Colorado River and its main tributaries: the Green, San Juan, and Little Colorado. Most of the remainder of the plateau is drained by the Rio Grande and its tributaries. The Colorado Plateau is largely made up of high desert, with scattered areas of forests. In the south-west corner of the Colorado Plateau lies the Grand Canyon of the Colorado River. Much of the Plateau's landscape is related to the Grand Canyon in both appearance and geologic history. The nickname "Red Rock Country" suggests the brightly colored ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
