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.

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.

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.
