Wichita Mountains

The Wichita Mountains can be found during the southwestern part of the U.S. state of Oklahoma.[1] It's the principal relief process while in the Southern Oklahoma Aulacogen, becoming the results of a unsuccessful continental rift. The mountains certainly are a northwest-southeast trending series of rocky promontories, several capped by five hundred million-12 months outdated granite. These have been exposed and rounded by weathering in the Pennsylvanian & Permian Durations. The jap conclude from the mountains delivers 1,000 feet (305 m) of topographic reduction within a region normally dominated by gently rolling grasslands.

The mountains are property to quite a few working ranches and quarry operations, the state reformatory, leisure properties and campsites, and scenic parklands. Fort Sill, property from the U.S. Military Discipline Artillery University, occupies a sizable percentage of the southeastern conclusion on the mountains.

Recreation

The Wichita Mountains Countrywide Wildlife Refuge, a favourite for hikers and rock climbers during the region, is found adjacent to Cache, Drugs Park, Indiahoma, and historic Meers, and is also a short drive from Lawton and Walters. Bison, elk and deer are shielded over the fifty nine,020-acre (23,880 ha) wildlife refuge. The refuge also manages a herd of longhorn cattle. A scenic freeway traversing the park permits leisurely views of these as well as other fauna.[2]

Backcountry camping is on the market inside the Charon Gardens Wilderness region.[three] The park is residence to a little number of fishing lakes. There are numerous trails for mountaineering. The Treasure Lake Occupation Corps website is situated in this article. More factors of fascination include things like the refuge's website visitors center, Holy Metropolis with the Wichitas, Quanah Parker Lake & Dam, Lake Jed Johnson, and Lake Lawtonka.

Good Plains State Park is situated close to the geographic Middle of the Wichita Mountains, north of your city of Mountain Park.

Quartz Mountain Nature Park and Arts Heart is really a recreation spot Found north of the city of Altus.

Geography

At 2,464 ft (751 m) Mount Scott is the next highest mountain in the Wichita Mountains Nationwide Wildlife Refuge boundary. Mount Pinchot in the Special Use Region [a] is 12 toes (4 m) taller.[four][5] A paved road results in the summit of Mount Scott, giving sights from the granite promontories on the west, the wind farm about the Slick Hills into the north, the lakes for the south and new data from Wichita Mountains east, Fort Sill, and Lawton. The highest peak from the Wichita Mountains (including regions outside the refuge) is Haley Peak, at two,481 ft (756 m). Haley Peak is found on non-public assets just outdoors the northwest corner from the refuge.[six]

History

When the area was Section of Indian reservations and as a consequence off-boundaries to non-Native People, the Wichita Mountains ended up rumored to consist of loaded gold deposits. When the region was very first opened up for settlement, quite a few prospectors staked mining promises, and towns have been laid out to provide the presumed bonanzas, but no economic deposits were found. The gold boom was extended by some unscrupulous assayers who found gold in each and every sample, nevertheless the miners finally gave up, abandoning ghost towns for example Wildman, Oklahoma.[seven][8]

Overview

The Wichita Mountains are rocky promontories and rounded hills fabricated from red and black igneous rocks, light-weight-colored sedimentary rocks, and boulder conglomerates. The Wichita Mountains ended up formed in 4 unique geologic episodes next a failed continental rift.

Magmatism induced by continental rifting just before and in the Cambrian Interval manufactured the granites and rhyolites (the crimson rocks), gabbroic rocks, anorthosites, and diabases (the black rocks).

Subsidence resulted in burial by sandstones and carbonates (the light-coloured rocks) throughout the early Paleozoic.

Uplift throughout the Pennsylvanian Ouachita Orogeny brought these rocks on the area as mountains.

Weathering and erosion over the Permian Time period flattened the mountains and produced a mantle of conglomerates.

The mountains themselves are Permian landforms included and preserved by river-borne sediments during the Permian and partly excavated only in current geological situations. Exposure of such fossil mountains is greatest in direction of the southeast; A great deal of the western Component of the Permian variety continues to be buried beneath sandstones and mudstones.

Facts

The geologic record in the region started Along with the deposition of late Precambrian to early Cambrian sandstones collectively known as the Tillman metasedimentary group.[nine] These sediments were being intruded by a coarse mafic layered advanced given that the area began to rift aside in the course of breakup with the Neoproterozoic continent, Pannotia.[10] The uncovered part of this device, named the Glen Mountains Layered Elaborate, is made up of gabbro, anorthosite and troctolite. Latest significant-precision courting yields an age of 532.forty nine ± 0.fifteen Ma.[11] These are definitely the dim grey rocks identified through the Raggedy Mountains, the central lowlands location of your wildlife refuge, and to the immediate north with the refuge.[12]

Uplift and erosion adopted, since the layered complex is unconformably overlain through the in depth lava flows on the Carlton Rhyolite Group.[9] The rhyolites undoubtedly are a brown-purple to orange porphyritic rock with 5–ten mm orange-coloured alkali feldspar crystals. A lot of the rounded hills on Fort Sill are created of the rhyolite, which includes Drugs Bluffs. Further publicity from the rhyolite is present in Blue Creek Canyon, where Oklahoma Freeway 58 cuts from the Slick Hills. Tabular intrusions of granite and plutons of hydrous gabbro exploited the boundary among the layered intricate and also the rhyolites.[thirteen] The granites, collectively named the Wichita Granite Group, range a bit in composition and texture. The granites type the peaks and highlands inside the japanese Wichitas plus the isolated peaks of the western Wichitas. Some are equigranular, but most are porphyritic.

The Mount Scott Granite is among the most extensively exposed Wichita Granite. It kinds the topographic element from which it will require its title, and it's distributed throughout the northern fifty percent of your wildlife refuge. Darkish rounded alkali feldspars, normally one particular centimeter or a lot less in diameter, dominate the porphyritic texture of this rock.[14] SiO2 amounts Within this granite vary from 72.8% to 75.eight%.[15]

Reasonably smaller and compositionally distinct plutons, called the Roosevelt Gabbros, are located in the eastern and central Wichita Mountains. Like the layered sophisticated, these are generally dark rocks. Not like the layered advanced, they consist of appreciable amounts of biotite, a mineral that varieties in magmas with elevated dissolved h2o. 1 of these bodies, the Mount Sheridan Gabbro, is exposed in roadcuts at Meers and underlies the Mount Scott Granite around the north aspect of the wildlife refuge. Weathered gabbroic soils are thicker and guidance much more vegetation than those generated on weathered granite, Hence the tree line to the north facet of Mount Sheridan approximates the Call concerning the Mount Sheridan Gabbro along with the Mount Scott Granite. Geologic interactions suggest which the granites and gabbros intruded at depths no higher than 50 percent a kilometer within the crust.[9] Insignificant uplift ensued, and magmatism concluded with the intrusive emplacement of subvolcanic capabilities: rhyolite and diabase dikes.[9] They are badly uncovered, with the exception of a significant diabase dike while in the Mount Scott Granite discovered during the recent widening of Oklahoma Condition Freeway forty nine, just west of Interstate forty four.

Subsequent the cessation of magmatism, the region subsided and was inundated by a shallow sea, causing the deposition of detrital sediments followed by carbonates.[sixteen] The transform marks the community expression from the Sauk Unconformity. The sunshine-colored rocks uncovered within the Slick Hills are decreased Paleozoic marine sediments, and are equivalent to those exposed in the Arbuckle Mountains, a hundred km on the east.

Through the Pennsylvanian Interval (330–290 million several years back) the area was subjected to intense pressure in the continental collision or orogeny which generated the Ouachita Mountains into the east.[seventeen] This resulted in faulting and folding striking together a WNW direction and contains the Arbuckle and Wichita Mountains of southern Oklahoma as well as the Amarillo Uplift of the Texas Panhandle.[17] Up to 20,000 toes (6,one hundred m) of local uplift transpired all through this time.[18]

This uplift locally made rugged mountains lessened by erosion to their current condition largely throughout the Pennslyvanian & Permian Durations. In depth weathering created the tors of the Charon Gardens location plus the "river" of boulders that descends the west slope of Mount Scott. Also, weathering made the bowling-ball sized boulders in the Permian Submit Oak Conglomerate locally located in and round the mountains. As well as outcrops with the conglomerate, the boulders are preserved while in the distinct rock properties of Drugs Park. Given that the Permian progressed, river sediments buried the Wichita Mountains, preserving them from more weathering. The latest geological erosion has eradicated these sediments, excavating these at the time buried fossil landforms.[9]

The most typical soil from the Wichita Mountains is Brico sequence, that has a topsoil of brown cobbly loam in excess of a reddish brown to crimson cobbly clay loam or clay subsoil.[19]
