Eagle Crags (California)
Eagle Crags is a elevation summit located in the Canaan Mountain Wilderness of Washington County in southwest Utah, United States. Description Eagle Crags is situated southeast of Rockville and 2.5 miles south of Zion National Park, and can be seen from Utah State Route 9. Topographic relief is significant as it rises in two miles on its north side above the Virgin River which drains precipitation runoff from this mountain. Its nearest higher neighbor is Lower Mountain, to the south, Shunesburg Mountain is four miles to the northeast, and Smithsonian Butte is four miles to the west-southwest. The uppermost part of this mountain is composed of light-colored Jurassic Navajo Sandstone which overlays the deep-red sandstone of the Kayenta Formation. Access is via the 2.8 mile Eagle Crags Trail which passes through pinyon–juniper woodland, sagebrush, blackbrush, yucca, and cacti as it gains 900 feet of elevation to the base of the sandstone pinnacles, spires, and crags.

Mountains Of Washington County, Utah
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Geology Of The Zion And Kolob Canyons Area
The geology of the Zion and Kolob canyons area includes nine known exposed formations, all visible in Zion National Park in the U.S. state of Utah. Together, these formations represent about 150 million years of mostly Mesozoic-aged sedimentation in that part of North America. Part of a super-sequence of rock units called the Grand Staircase, the formations exposed in the Zion and Kolob area were deposited in several different environments that range from the warm shallow seas of the Kaibab and Moenkopi formations, streams and lakes of the Chinle, Moenave, and Kayenta formations to the large deserts of the Navajo and Temple Cap formations and dry near shore environments of the Carmel Formation. Subsequent uplift of the Colorado Plateau slowly raised these formations much higher than where they were deposited. This steepened the stream gradient of the ancestral rivers and other streams on the plateau. The faster-moving streams took advantage of uplift-created joints in the rock ...

Cold 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 (''BSk'' and ''BSh'') 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 it usually can't 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): *multiply ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. 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'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johnson Mountain (Utah)
Johnson Mountain is a Navajo Sandstone summit located in Zion National Park, in Washington County of southwest Utah, United States. Description Johnson Mountain is located immediately southeast of Springdale, towering above the town and the floor of Zion Canyon. It is wedged between the North and East Forks of the Virgin River which drain precipitation runoff from this mountain. Its nearest higher neighbor is The Watchman, to the north-northeast, and Mount Kinesava is positioned directly across the canyon to the northwest. Shunesburg Mountain is set to the southeast, directly across the mouth of Parunuweap Canyon. This feature's name was officially adopted in 1934 by the U.S. Board on Geographic Names. It is named for Nephi Johnson (1833–1919), a Mormon missionary, interpreter, explorer, and the first white man to visit Zion Canyon. In 1858 a Paiute guide by the name of ''Nauguts'' led Nephi into the Zion Canyon area of the upper Virgin River.Kiver, Eugene P.; Harris, D ...

Mount Kinesava
Mount Kinesava is a sandstone mountain summit located in Zion National Park, in Washington County of southwest Utah, United States. Description Mount Kinesava is located immediately west of Springdale, towering above the town and the floor of Zion Canyon. Precipitation runoff from this mountain drains into tributaries of the Virgin River. Its nearest higher neighbor is The West Temple, to the northeast. Other notable mountains wthin view from the summit include The Watchman to the east-southeast, Bridge Mountain to the east-northeast, and Mount Spry is positioned to the northeast. This feature's name was officially adopted in 1934 by the U.S. Board on Geographic Names. It is so named for ''Kinesava'', the Paiute deity of trickery. Climate Spring and fall are the most favorable seasons to visit Mount Kinesava. According to the Köppen climate classification system, it is located in a Cold semi-arid climate zone, which is defined by the coldest month having an average m ...

Pinyon–juniper Woodland
Pinyon–juniper woodland, also spelled piñon–juniper woodland, is a vegetation type (biome) of Western United States higher elevation deserts, characterized by being an open forest dominated by low, bushy, evergreen junipers (''Juniperus osteosperma,''Damian Fagan, Canyon Country Wildflowers, p. 3Pam MacKay, Mojave Desert Wildflowers, p19-20 ''Juniperus californica'',Karen Wiese, Sierra Nevada Wildflowers, 2013, p. 18 '' Juniperus grandis''), pinyon pines (''Pinus monophylla'', ''Pinus edulis''), and their associates which vary from region to region.Ronald J. Taylor, Sagebrush CountryLaird Blackwell, Great Basin Wildflowers, p5-6 The woodland's density and crown height varies dramatically depending on the site's soil and climate, the age of the stand, and the particular species present, with mature trees ranging in height from as low as 2 meters up to 15 meters. At lower elevations, junipers often predominate and trees are spaced widely, bordering on and mingling with grasslan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kayenta Formation
The Kayenta Formation is a geological formation in the Glen Canyon Group that is spread across the Colorado Plateau province of the United States, including northern Arizona, northwest Colorado, Nevada, and Utah. Traditionally has been suggested as Sinemurian-Pliensbachian, but more recent dating of detrital zircons has yielded a depositional age of 183.7 ± 2.7 Ma, thus a Pliensbachian-Toarcian age is more likely A previous depth work recovered a solid Lower-Middle Pliensbachian age from measurements done in the Tenney Canyon. This rock formation is particularly prominent in southeastern Utah, where it is seen in the main attractions of a number of national parks and monuments. These include Zion National Park, Capitol Reef National Park, the San Rafael Swell, and Canyonlands National Park. The Kayenta Formation frequently appears as a thinner dark broken layer below Navajo Sandstone and above Wingate Sandstone (all three formations are in the same group). Together, these thre ...
