WYOMING  , one of the Central Western states of the See also:

United States of See also:America, situated between the See also:parallels of See also:latitude 41° and 45° N., and the meridians of See also:longitude 27° and 340 W. of See also:Washington . It is bounded on the N. by See also:Montana, on the E. by S . Dakota and See also:Nebraska, on the S. by See also:Colorado and See also:Utah, and on the W. by Utah, See also:Idaho, and a small southward See also:projection of Montana . The See also:state has a length of about 375 M . E. and W. along its See also:southern border and a breadth of 276 1n . N. and S . It has an See also:area of 97,914 sq. m., of which 320 sq. m. are See also:water See also:surface See also:Physical Features.—The greater portion of the state belongs to the See also:Great Plains See also:Province, which extends from N. to S. across the United States between the tooth See also:meridian and the Rocky Mountains . Within this province are found the See also:Black Hills of S . Dakota, and their W. slopes extend across the boundary into N.E . Wyoming . The N.W. portion of the state is occupied by the S. end of the See also:Northern Rocky See also:Mountain Province; and the N. end of the Southern Rockies extends across the Colorado See also:line into southern Wyoming . The Great Plains in Wyoming have an See also:elevation of from 5000 to 7000 ft. over much of the state, and consist of See also:flat or gently See also:rolling See also:country, barren of See also:tree growth, but often covered with nutritious See also:grasses, and affording pasturage for vast See also:numbers of live stock .

Erosion buttes and mesas occasionally rise as picturesque monuments above the See also:

general level of the plains, and in the vicinity of the mountains the plains strata, elsewhere nearly See also:horizontal, are See also:bent sharply upward and carved by erosion into " hogback " ridges . These features are well See also:developed about the Bighorn Mountains, an outlying member of the Rockies which boldly interrupts the continuity of the plains in See also:north-central Wyoming . The plains sediments contain important See also:coal beds, which are worked in nearly every See also:county in the state . In the region between the Northern and Southern Rockies, the plains are interrupted by See also:minor Mountain See also:groups, volcanic buttes and See also:lava flows, among which the See also:Leucite Hills and See also:Pilot See also:Butte are prominent examples . Notwithstanding these elevations, this portion of the state makes a distinct break in the continuity of the Northern and Southern Rockies, giving a broad, relatively See also:low pass utilized by the See also:Oregon Trail in See also:early days, and by the See also:Union Pacific railway at a later See also:period . The Black Hills See also:District in the N.E. contains the Little See also:Missouri Buttes and the Mato Tepee (or See also:Devil's See also:Tower), prominent erosion remnants of volcanic intrusions . See also:Local glaciation has modified the higher levels of the Bighorn Mountains, giving glacial cirques, alpine peaks and many mountain lakes' and waterfalls . Several small glaciers still remain about the See also:base of See also:Cloud See also:Peak, the highest See also:summit in the range (13,165 ft.) . The Southern Rockies end in broken ranges with elevations of 9000 ft. and over . That portion of the Northern Rockies extending into the N.W. of the state affords the most magnificent scenery . Here is the Yellowstone See also:National See also:Park (q.v.) . Just S. of the Park the Teton Mountains, rising abruptly from the low See also:basin of See also:Jackson's Hole to elevations of 1o,00o and 11,000 ft., See also:form a striking feature .

In the See also:

Wind See also:River Range, farther S.E., are Gannett Peak (13,775 ft.), the highest point in the state, and See also:Fremont Peak (13,720 ft.) . In addition to the hot springs of the Yellowstone region, mention should be made of large hot springs at Thermopolis and See also:Saratoga, where the water has a temperature of about 135° F . Much of the state is drained by branches of the Missouri river, the most important being the Yellowstone, Bighorn and See also:Powder See also:rivers flowing N., and the See also:Cheyenne and North See also:Platte flowing E . The See also:Green river, a See also:branch of the Colorado, flouts S. from the S.W. of the state, while the Snake river rises farther N. and flows W. to the Pacific drainage . S.W. of the centre of the state is an area with no outward drainage, the streams emptying into See also:desert lakes . See also:Fauna.—Great herds of bison formerly ranged the plains and a few are still preserved in the National Park . The See also:white-tailed See also:Virginia See also:deer inhabits the bottom lands and the See also:mule deer the more open country . See also:Lewis's See also:prairie See also:dog, the cottontail See also:rabbit, the See also:coyote, the See also:grey See also:wolf and the See also:kit See also:fox are all animals of the plains . In the mountains are See also:elk, See also:puma, See also:lynx, the varying See also:hare and snowshoe rabbit, the yellow-haired See also:porcupine, Fremont's and See also:Bailey's squirrels, the mountain See also:sheep, the four-striped chipmunk, Townsend's spermoprile, the prong-horned See also:antelope, the See also:cinnamon See also:pack-See also:rat, grizzly, See also:brown, silvertip and black bears and the See also:wolverine . Other animals, more or less See also:common, are the black-tailed deer, the jackrabbit, the See also:badger, the See also:skunk, the See also:beaver, the See also:moose and the See also:weasel . The prairie See also:rattlesnake is common in the dry plains country . The streams are well stocked with See also:rainbow and See also:brook See also:trout .

The former See also:

fish were introduced from See also:California in 1885 . They thrive in the Wyoming streams and rivers and are See also:superior See also:game fish . Specimens of eight and ten pounds See also:weight have been taken by See also:rod and See also:fly fishermen from the Big See also:Laramie river . Other fish native to the See also:waters of the state are the See also:sturgeon, catfish, See also:perch (locally called See also:pike), See also:buffalo fish, flathead and sucker . There is a great variety of birds . Eared grebes and See also:ring-billed gulls breed on the sloughs of the plains, and rarely the white See also:pelican nests about the See also:lake shores . Here, too, breed many See also:species of ducks, the mallard, See also:gadwall, baldpate, three species of See also:teal, See also:shoveler, See also:pin-tail, hooded mergansers, and See also:Canada geese; other ducks and geese are migrants only . Formerly the See also:trumpeter See also:swan nested here . On the plains a few waders breed, as the avocet, western willet and See also:long-billed See also:curlew; but most are birds of passage . At high altitudes the mountain See also:plover is found; the dusky See also:grouse haunts the forests above 8000 ft.; the white-tailed See also:ptarmigan is See also:resident in the alpine regions; and on the plains are found the prairie See also:sharp-tailed grouse and the See also:sage-See also:hen . The See also:turkey-See also:buzzard is found mainly in the plains country . Various See also:hawks and owls are common; the See also:golden See also:eagle nests on the mountain crags and the burrowing See also:owl on the plains .

The red-naped sapsucker and Lewis's See also:

woodpecker are conspicuous in wooded lands; See also:Nuttall's poor-will, Say's See also:phoebe, the desert horned See also:lark, See also:Bullock's See also:oriole, the yellow-headed See also:blackbird and McCown's longspur are characteristic of the open lowlands . See also:Flora.—See also:Forest growth in Wyoming is limited to the highest mountain ranges, the most important forests being in the Black Hills region in the N.E., on the See also:lower slopes of the Bighorn Mountains, and in the Rocky Mountain ranges of the N.W. of the state, including Yellowstone National Park . The yellow See also:pine is the most important tree in the Bighorns, and small See also:lodge-See also:pole pine makes up the greater See also:part of the N.W. forests . White See also:fir is found above the foothill See also:zone, and heavy growths of cottonwood along the streams in the Bighorn region . The See also:Douglas spruce and Rocky Mountain white pine are common in the forests of the See also:Medicine See also:Bow Mountains, from which much of the native See also:lumber used in the S. of the state is secured . Other trees are the See also:juniper, See also:willow, green ash, See also:box See also:elder, scrub See also:oak, See also:wild See also:plum and wild See also:cherry . Occasional cottonwoods along streams are the only trees on the plains . The common sage See also:brush, See also:artemisia, is the characteristic See also:shrub of the plains where the See also:soil is comparatively See also:free from See also:alkali, and is abundant in the valleys of the arid foothills . Where alkali is See also:present, the plains may be nearly barren, or covered with grease See also:wood and species of atriplex, including the so-called white sage . Grease wood is likewise abundant in the foothills wherever the soil contains alkali . Various species of nutritious grasses See also:cover much of the plains and foothills, and even clothe the apparently barren mountain peaks . See also:Climate.—In the lower Bighorn Valley, summer temperatures rise to 95° or 100°, but at heights of 600o to 7000 ft. on neighbouring ranges, summer temperatures seldom rise above 90°, and frosts may occur at any See also:time Elevations under 6000 ft. have a mean See also:annual temperature of from 40° to 47°, but high mountain areas and See also:cold valleys may have mean temperatures as low as 34° The See also:air is clear and dry, and although temperatures of Too° are recorded, See also:sun-strokes are practically unknown .

See also:

Winter temperatures as low as -51 ° have been recorded, but these very low temperatures occur in the valleys rather than on the higher elevations . The cold is sharp and bracing rather than disagreeable, on See also:account of the dryness of the air; and the periods of cold See also:weather are generally of See also:short duration . The winter climate is remarkably pleasant as a See also:rule, and outdoor See also:work may usually be carried on without discomfort . The following figures give some.See also:idea of the See also:climatic See also:variations . At Basin, in the Bighorn Valley, the mean winter temperature is 16°, the summer mean 72° . Thayne, on the mountainous W. border of the state, nas a winter mean of 19°, and a summer mean of but 59°; Cheyenne in the S.E., has a winter mean of 27°, and a summer mean of 65° . The percentage of See also:sunshine in the state is high . Precipitation varies in different areas from 8 to 20 in., the See also:average for the state being 12.5 in . Wyoming thus belongs with the arid states, and See also:irrigation is necessary for See also:agriculture . A greater precipitation doubtless prevails on the higher mountains, but See also:trust-worthy records are not available . See also:Spring is the wettest See also:season . The prevailing winds are W. and reach a high velocity on the level plains .

Soil.—While some of the more arid districts have soils so strongly alkaline as to be practically unreclaimable, there are extensive areas of fertile lands which only require irrigation to make them highly productive . Alluvial deposits brought down by mountain streams, and strips of floodplam along larger streams on the plains are very fertile and well repay irrigation . Lack of water rather than poverty of soil renders most of the plains region See also:

fit for grazing only . In the mountains, ruggedness combines with thin and scattered soil to make these districts of small agricultural value . Agriculture.—The See also:total area in farms in 188o was 124,433 acres, of which 83,122 acres (66.8 %) were improved; in 1900 it was 8,124,536 acres, of which 792,332 acres (9.8 %) were improved . The large increase in unimproved acreage in farms was principally due to the increased importance in sheep-raising . In 1909 Wyoming ranked first among the states in the number of sheep and the See also:production of See also:wool . The number of sheep in 1909 was 7,316,000, valued at $32,190,000, being more than one-eighth in numbers and nearly one-seventh in value of all sheep in the United States . The production of wool in 1909 was 38,400,000 lb of washed and unwashed wool and 12,288,000 lb of scoured wool . The average weight per fleece was 8 lb . The See also:Bureau of See also:Animal See also:Industry of the U.S . See also:Department of Agri-culture has made experiments in breeding range sheep in Wyoming .

The total number of neat See also:

cattle on farms and ranges in 1910 was 986,000 (including 27,000 milch cows) valued at $26,277,000; horses, 148,000, valued at $12,284,0oo;i mules, 2000, valued at $212,000; and See also:swine, 21,000, valued at $178,000 . In 1909 the See also:hay See also:crop (See also:alfalfa, native hay, See also:timothy hay, &c.) was 665,000 tons, valued at $5,918,000 and raised on 277,000 acres . The cereal crops increased enormously in the See also:decade 1899-1909 . The See also:principal cereal crop in 1909 was oats, the product of which was 3,500,000 bushels, grown on See also:Ioo,000 acres and valued at $1,750,000 . The See also:wheat crop increased from 4674 bushels in 1879 to 2,297,000 bushels in 1909, grown on 80,000 acres and valued at $2,274,000 . The product of See also:Indian See also:corn in 1909 was 140,000 bushels, grown on 5000 acres and valued at $109,000 . See also:Mining.—The development of Wyoming's naturally See also:rich See also:mineral resources has been retarded by inadequate transport and by in-sufficient See also:capital . The value of the state's mineral product was $5,684,286 in 1902 and $9,453.341 in 1908 . In 1908 Wyoming ranked twelfth among the states of the Union in the value of its output of bituminous coal . Other mineral products of the state are The breed of horses in Wyoming has improved rapidly; in 1904, when the U.S . Department of Agriculture See also:purchased eighteen mares and a stallion in See also:hope of improving the See also:American See also:carriage See also:horse, six of the mares were from Wyoming and were principally of See also:Morgan See also:stocks.See also:copper, See also:gold, See also:iron, See also:petroleum, See also:asbestos, soda, See also:silver and See also:lead, See also:gypsum, See also:stone and See also:clay products . The See also:original coal See also:supply of the present state has been estimated (by the United States See also:Geological Survey) at 424,085,000,000 short tons of the bituminous or sub-bituminous variety, this amount being second only to that for North Dakota, 500,000,000,000 short tons; which, however, is entirely See also:lignite .

Coal was first See also:

mined. in what is now Wyoming in 1865, probably in connexion with the See also:building of the Union Pacific railway, and the See also:pro-duct in that See also:year was 800 short tons . Thereafter the industry developed steadily and the product in 1908 was 5,489,902 tons, valued at $8,868,157 . In 1908 (and for several years before) the largest product of coal (2,180,933 tons) came from Sweetwater county, in the S.W. of the state, and Uinta county (adjoining Sweet-water county on the W.) had the next largest product, 1,380,488 tons . See also:Sheridan county, in the north-central part of the state, See also:Carbon county, in the See also:south-central part and See also:Weston county in the N.E. were the next largest producers . The product of coal to the end of 1908 was 125,000,000 short tons, or 0.029 % of the estimated supply . The mining product next in value to coal in 1908 was copper, taken chiefly in Carbon county in a zone of brecciated See also:quartzite underlying schist, the original ore being chalcopyrite, with possibly some pyrite, a secondary enrichment, which has produced important bodies of chalcocite in the upper workings, but these are replaced by chalcopyrite at greater See also:depth . The production in 1908 was 2,416,197 lb, valued at $318,938 . The gypsum product (from the Laramie plains) in 1908 was 31,188 tons, valued at $94,935 . There are extensive deposits of petroleum and natural See also:gas, which have become of commercial importance . Oil has been found in eighteen different districts, the See also:fields elds being known as follows:—The See also:Carter, See also:Hilliard, Spring Valley and Twin See also:Creek in Uinta county; the Popo Agie, See also:Lander, Shoshone, Beaver and a part of Dutton in Fremont county; the Rattlesnake, Arrago, Oil Mountain and a part of Dutton, Powder river and See also:Salt Creek in Natrona county; part of Powder river and Salt Creek in See also:Johnson county; See also:Newcastle in Weston county; Belle Fourche in Crook county; Douglas in Converse county and Bonanza in Bighorn county . The Popo Agie and Lander fields produce the largest quantities of oil, the See also:wells being partly gushers from which a heavy See also:fuel oil is obtained . This is now being used by the See also:Chicago & North Western Railroad See also:Company on its locomotives, and it is also used in See also:Omaha (Nebraska) by manufacturing establishments .

There is a great variety in the grades of See also:

oils produced in the state, ranging from the heavy asphaltic oils of the Popo Agie and Lander fields to the high-grade See also:lubricants and superior See also:light products obtained from the wells in the Douglas, Salt Creek and Uinta county fields . Natural gas in quantity has been found in the Douglas See also:field and in Bighorn county . The iron deposits are very extensive, and the ores consist of red haematites, magnetites, titanic, chrome and See also:manganese irons . In nearly every county there are See also:veins of iron ore of varying extent and quality, the most important being at Hartville, Laramie county, Iron Mountain, See also:Albany county, the See also:Seminole and Rawlins in Carbon county . The Hartville ores are remarkable for their high grade and purity, See also:running from 6o to 70 % metallic iron, with 2i to 5% See also:silica, and only traces of See also:sulphur and See also:phosphorus . The ore is a red See also:haematite occurring in See also:slate . The iron ore from this district obtained the See also:grand See also:prize at the See also:World's See also:Fair held in Chicago in 1893, in competition with iron ores from all parts of the world . The Hartville iron deposits are worked by the Colorado Fuel & Iron Company, which See also:ships large quantities of ore to its furnaces at See also:Pueblo, Colorado . The See also:discovery of natural gas in the Douglas oil field has opened up the possibility of working a smelting plant at the mines by means of this cheap and convenient, fuel . The distance to be covered by a See also:pipe line is not prohibitive, and the See also:matter has been under See also:consideration by the owners and lessees of the iron mines . There are See also:sandstone deposits in Carbon county, which supplied the stone for the Capitol at Cheyenne and the state See also:penitentiary; and from the Iron mountain quarries in Laramie county was taken the white variety used,in building the See also:Carnegie library and the Federal building in Cheyenne . Sandstones and quartzites were also quarried in 1902 in Albany, Crook and Uinta counties .

Limestone occurs in thick formations near Lava Creek, and in the valley of the See also:East See also:Fork of the Yellowstone river; also near the summit of the Owl Creek range, and in the Wind River range . Gold was discovered on the Sweetwater river in 1867, and placer and See also:quartz deposits have been found in almost every county in the state . Sulphur has been found near See also:Cody and Thermopolis . Irrigation.—The irrigable area of Wyoming is estimated at about 6,200,000 acres, lying chiefly in Bighorn, Sheridan and Johnson counties in the N.W. of the state, and in Laramie, Albany and Carbon counties in the S.E., though there are large tracts around the See also:head-waters of the Bighorn river, in Fremont county in the See also:west-central part, along the North Platte river and its tributaries in Converse county in the central part, and along the Green river and its tributaries in Sweetwater and Uinta counties in the S.W . Under the See also:Carey See also:Act and its amendments See also:Congress had in 1909 given to the state about 2,000,000 acres of desert See also:land on See also:condition that it should be reclaimed, and in that year about 800,00o acres were in See also:process of reclamation, mostly by private companies . Settlers intending to occupy such lands must satisfy the state that they have entered into contracts with the irrigating company for a sufficient water-right and a perpetual See also:interest in the irrigation See also:works . The principal undertaking of the Federal See also:government is the Shoshone project in Bighorn county . This provides for a storage See also:reservoir, controlled by Shoshone See also:dam on Shoshone river, about 8 m. above Cody; a See also:canal diverting water from Shoshone reservoir See also:round the N. of Shoshone dam and covering lands in the vicinity of Cody, Corbett, Eagle See also:Nest and Ralston; a dam at Corbett about 16 m. below the reservoir diverting water to Ralston reservoir and thence to lands in the vicinity of Ralston, See also:
