The idea is still better confirmed farther north in Wyoming, where the Laramie Range, flanked with upturned strata on the east and west, is for the most part a broad upland at altitudes of 7000 or 8000 ft., with no strong surmounting summits, and as yet no deep carved valleys.
Flanking strata are even better exhibited in the Bighorn Mountains, the front range of northern Wyoming, crescentic in outline and convex to the northeast, like the Laramie Range, but much higher; here heavy sheets of limestone arch far up towards the range crest, and are deeply notched where consequent streams have cut down their gorges.
Its eastern part is drained north-eastward through a gorge that separates the Laramie and Rattlesnake (Front) ranges by the North Platte river to the Missouri-Mississippi; its western part, where the basin floor is much dissected, often assuming a bad-land expression, is drained southward by the Green river, through a deep canyon in the Uinta Ran~e to the Colorado river and then to the Pacific. The Bighorn basin has a moderately dissected floor, drained north-eastward by Bighorn river through a deep canyon in the range of the same name to the Missouri.
The Laramie is the great coalbearing series of the west, and corresponds in its general physical make-up and in its mode of origin to the Coal Measures of the east.
The Fort Union stage is closely associated with the Laramie, and their separation has not been fully effected.
Laramie formation 2000 ft.
The several ranges of the Cordillera show very different types of structure and were formed at different ages, the Selkirks with their core of pre-Cambrian granite, gneiss and schists coming first, then the Coast Ranges, which seem to have been elevated in Cretaceous times, formed mainly by a great upwelling of granite and diorite as batholiths along the margin of the continent and sedimentary rocks lying as remnants on their flanks; and finally the Rocky Mountains in the Laramie or early Eocene, after the close of the Cretaceous.
Specimens of eight and ten pounds weight have been taken by rod and fly fishermen from the Big Laramie river.
The gypsum product (from the Laramie plains) in 1908 was 31,188 tons, valued at $94,935.
In nearly every county there are veins of iron ore of varying extent and quality, the most important being at Hartville, Laramie county, Iron Mountain, Albany (disambiguation)|Albany county, the Seminole and Rawlins in Carbon county.
There are sandstone deposits in Carbon county, which supplied the stone for the Capitol at Cheyenne and the state penitentiary; and from the Iron mountain quarries in Laramie county was taken the white variety used in building the Carnegie library and the Federal building in Cheyenne.
Of the state, and in Laramie, Albany and Carbon counties in the S.E., though there are large tracts around the headwaters of the Bighorn river, in Fremont county in the 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.

The principal cities of the state (with population) in 1900 were: Cheyenne, 14,087; Laramie, 8207; Rock Springs, 4363; Rawlins, 2317, and Evanston, 2110.
At the head of the educational system is the University of Wyoming (1886), at Laramie (q.v.); it is governed by a board of trustees consisting of its president, the superintendent of public instruction, and nine other members appointed by the governor with the concurrence of the Senate for a term of six years.
Bonneville was the first to cross the Rockies with wagons (1832),' and two years later Fort Laramie, near the mouth of the Laramie river, was established to control the fur trade of the Arapahoes, Cheyennes and Sioux.
For the latter reason the National Congress on the 19th of May 1846 authorized the construction at intervals along the trail of military stations for the protection of the emigrant trains, and Fort Kearny was built (1848) and Fort Laramie was purchased (1849).
By a treaty negotiated at Fort Laramie in 1851, the Arapahoes, Sioux, Cheyennes and others agreed to confine themselves within the territory bounded by 100 and 107° W.
Latitude; but, besides minor conflicts, a considerable portion of the garrison of Fort Laramie was killed in 18J4 and there was trouble for more than twenty years.
Congress in 1867 appointed a commission to arrange a peace, but not until 1868 (29th April, at Fort Laramie) were any terms agreed upon.
Cheyenne was laid out by the Union Pacific Railroad (July 1867), a city government was established in August, newspapers began publication, and Laramie county was organized before the arrival of the first railway train on the 13th of November 1867.
Almost the same scenes followed the laying off of Laramie in April 1868, when 400 lots were sold during the first week and 500 habitations were erected within a fortnight.
A bill to organize the Territory of Wyoming had been introduced into Congress in 1865, and in 1867 the voters of Laramie county had chosen a delegate to Congress.

The coal-bearing rocks are confined to the Upper Cretaceous, and almost wholly to the Laramie formation.

Foot of the Laramie range, at an altitude of 6050 ft.; the surrounding country is given up to mining (lignite and iron), grazing and dry-farming.
An extensive literature has grown up relating to these Laramie strata, for owing to the Tertiary aspect of the contained plants, geologists were slow to recognize that they could be truly contemporaneous and interbedded with others yielding Cretaceous animals.
In addition to this, the earlier writers included in the Laramie series many deposits now known to be of later date and truly Tertiary, and the process of separation is even now only partially completed.
It will be safest in these circumstances to accept as our guide to the true Laramie flora the carefully compiled " Catalogue " of F.
According to this catalogue, the true Laramie flora includes about 250 species, more than half of which are deciduous forest trees, herbaceous Dicotyledons, Monocotyledons and Cryptogams, all being but poorly represented.
