In contrast, the Yellowstone is a stream of bright clear water running over a gravelly bed and among numerous forest-clad islands.
The Yellowstone is navigable for about 300 m.
Among the larger privately irrigated tracts are: 16,000 to 18,000 acres in Yellowstone county, fed by a canal built by the Billings Land & Irrigation Company; about 35,000 acres of orchard land in the Bitterroot Valley, in Ravalli county, irrigated by canals from Lake Como, a natural reservoir; and 100,000 acres in Missoula county, to be watered from a 28 ft.
Among them are: the Huntley project in Yellowstone county, begun in 1904 and practically completed in 1908, covering land formerly in the Crow Indian reservation, the irrigable area being 28,921 acres; the Lower Milk river project (and the subsidiary St Mary project), in Chouteau, Valley and Teton counties, by which the water of St Mary river 1 is stored and diverted to the headquarters of the Milk river to irrigate an area of 300,000 acres; the Sun river project (Teton, Lewis and Clark, Chouteau and Cascade counties), by which, as the ordinary flow of that river is already utilized for irrigation, the flood waters are stored and carried to the higher bench lands of the district; in Montana (Dawson county) and North Dakota (McKenzie county), the Lower Yellowstone project; and the Blackfeet project, to irrigate the Blackfeet reservation in Teton county.
The principal sheep-raising counties are Custer, Yellowstone, whither many sheep are brought to be fattened, Rosebud, Beaverhead, Valley, and Meagher.

Some light grey sandstone found in Rocky Canon, Gallatin county, looks much like the Berea (Ohio) sandstone; and a sandstone quarried at Columbus, Yellowstone county, was manufactured into grindstones equal to those made from the Berea stone.
The Oregon Short Line from the south connects with the Northern Pacific, the Great Northern, and the Chicago, Milwaukee & Puget Sound at Butte, and the Burlington system, also from the south, connects with the Northern Pacific at Billings, Yellowstone county.
The report of Lewis and Clark attracted many traders and trappers, and within a few years the Missouri Fur Company, the Rocky Mountain Fur Company, the Hudson Bay Company and the American Fur Company had established fortified trading posts on the Missouri, the Yellowstone, the Marias, the Milk and other rivers; the most prominent among these was Fort Benton, which was established in 1846 at the head of navigation on the Missouri, and was made the headquarters of the American Fur Company.
The " Yellowstone," a steamboat sent out by the American Fur Company, ascended the Missouri to Fort Pierre in 1831 and to the mouth of the Yellowstone river in 1832.

The grizzly bear is now rare in the United States, save in the Yellowstone Park and the Clearwater Mountains of Idaho, though more common in British Columbia.
It is in association with this field of extinct volcanic activity that a remarkable group of geysers and hot springs has been developed, from which the Yellowstone river, a branch of the Missouri, flows northeastward, and the Snake river, a branch of the Columbia, flows south-westward.
The geyser district is held as a national domain, the Yellowstone Park.
Thus the uplifted, dislocated and dissected lava sheets of the Yellowstone National Park in the Rocky Mountains on the east (about the headwaters of the Snake river) are associated with the older lavas,of the Columbian plains.
In 1856 he was engaged under the United States government, and commenced a series of investigations of the Western Territories, one result of which was his Geological Report of the Exploration of the Yellowstone and Missouri Rivers in 1859-1860 (1869).
His other publications were: Sun Pictures of Rocky Mountain Scenery (1870); The Yellowstone National Park, illustrated by chromolithographic reproductions of water-colour sketches by Thomas Moran (1876); The Great West: its Attractions and Resources (1880).
YELLOWSTONE NATIONAL PARK, an American national reservation, situated mainly in N.W.

The only railway approaches to the park are a branch of the Northern Pacific railway up the valley of the Yellowstone to the main gate at Gardiner, Montana, and a branch of the Oregon Short Line up the valley of the North Fork of the Snake to Yellowstone, Montana.
Automobiles are not allowed within the park, and the principal means of conveyance is by stage coaches and by a steamboat on Yellowstone Lake.
In the west of North America, and in some of its islands, a pie is found which extends to the upper valleys of the Missouri and the Yellowstone, and has long been thought entitled to specific distinction as P. hudsonia; but its claim thereto is now disallowed by some of the best ornithologists of the United States, and it can hardly be deemed even a geographical variety of the Old-World form.
