Mount Jefferson (Bitterroot Range)
Mount Jefferson is a mountain located on the Continental Divide between Fremont County of northeastern Idaho and Beaverhead County of southwestern Montana. Mount Jefferson is the highest point of the Centennial Mountains, whose crest runs along the Continental Divide and can be climbed using a class 2 route (scramble) from the access road to neighboring Sawtell Peak. The south and west slopes of Mount Jefferson drain into Hell Roaring Creek, thence into Red Rock Creek, the Red Rock River, the Beaverhead River, the Jefferson River, the Missouri River, the Mississippi River, and into the Gulf of Mexico. Brower's Spring, the source of Hell Roaring Creek, on the mountain's east flank in Montana, is considered the absolute headwaters of the Missouri River. The northeast slope of Mount Jefferson drains into the South Fork of Duck Creek, thence into Henrys Lake, the Henrys Fork of the Snake River, the Columbia River, and into the Pacific Ocean. The mountain is named for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centennial Mountains
The Centennial Mountains are the southernmost sub-range of the Bitterroot Range in the U.S. states of Idaho and Montana. The Centennial Mountains include the Western and Eastern Centennial Mountains. The range extends east from Monida Pass along the Continental Divide to Henrys Fork NNW of Ashton, Idaho; bounded on the west by Beaver Creek, on the north by Centennial Valley and Henrys Lake Mountains, on the east by Henrys Lake Flat, and on the south by Shotgun Valley and the Snake River Plain. The highest peak in the range is Mount Jefferson. They are one of only a few ranges within the Rocky Mountains that trend west to east, and the Continental Divide runs along their ridge line. The Western Centennial Mountains extends west from the Eastern Centennial Mountains along the Continental Divide to Monida Pass, 25 mi NE of Dubois, Idaho; Snake River Plain, on the north by Centennial Valley, and the east by a line connecting Odell Creek and an unnamed tributary, in Montana, ...

Brower's Spring
Brower's Spring is a spring in the Centennial Mountains of Beaverhead County, Montana that was marked by a surveyor in 1888 as the ultimate headwaters of the Missouri River and thus the fourth longest river in the world, the Mississippi-Missouri River. The spring is named for Jacob V. Brower who in 1896 declared it to be the source of the Missouri in his book published by the Pioneer Press titled ''The Missouri river and its utmost source''. He visited the site in 1895 and buried a copper plate upon which the name of the river and the date were engraved. The spring is further than the spot Meriwether Lewis reported in 1805 as the source of the river above Lemhi Pass on Trail Creek. Both sources are near the Continental Divide in Montana. It is upstream from where the name "Missouri River" is first used. Though the copper plate has not been located, the site of Brower's Spring is believed to be at about on the north fork of where Hell Roaring Creek divides near its sou ...

Mountains Of Idaho
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Widgeon Pond, Red Rock Lakes NWR (14282591676)
The wigeons or widgeons are a group of birds, dabbling ducks currently classified in the genus '' Mareca'' along with two other species. There are three extant species of wigeon, in addition to one recently extinct species. Biology There are three extant species: the Eurasian wigeon (''Mareca penelope''), the American wigeon (''M. americana'') and the Chiloé wigeon (''M. sibilatrix''). A fourth species, the Amsterdam wigeon (''Mareca marecula''), became extinct in the 19th century. The wigeons' closest relatives, forming with them the genus ''Mareca'', are the gadwall and the falcated duck The falcated duck or falcated teal (''Mareca falcata'') is a gadwall-sized dabbling duck from the east Palearctic (East Siberia and Mongolia to North Japan; wintering to India). Taxonomy The closest relative of this species is the gadwall, follo .... All three wigeons are similarly shaped, with a steep forehead and bulbous rear to the head. Males have a distinctive breeding plumage, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Jefferson
Thomas Jefferson (April 13, 1743 – July 4, 1826) was an American statesman, diplomat, lawyer, architect, philosopher, and Founding Father who served as the third president of the United States from 1801 to 1809. He was previously the nation's second vice president under John Adams and the first United States secretary of state under George Washington. The principal author of the Declaration of Independence, Jefferson was a proponent of democracy, republicanism, and individual rights, motivating American colonists to break from the Kingdom of Great Britain and form a new nation. He produced formative documents and decisions at state, national, and international levels. During the American Revolution, Jefferson represented Virginia in the Continental Congress that adopted the Declaration of Independence. As a Virginia legislator, he drafted a state law for religious freedom. He served as the second Governor of Virginia from 1779 to 1781, during the Revolutionary War. In 1785 ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Columbia River
The Columbia River ( Upper Chinook: ' or '; Sahaptin: ''Nch’i-Wàna'' or ''Nchi wana''; Sinixt dialect'' '') is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the U.S. state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven US states and a Canadian province. The fourth-largest river in the United States by volume, the Columbia has the greatest flow of any North American river entering the Pacific. The Columbia has the 36th greatest discharge of any river in the world. The Columbia and its tributaries have been central to the region's culture and economy for thousands of years. They have been used for transportation sinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snake River
The Snake River is a major river of the greater Pacific Northwest region in the United States. At long, it is the largest tributary of the Columbia River, in turn, the largest North American river that empties into the Pacific Ocean. The Snake River rises in western Wyoming, then flows through the Snake River Plain of southern Idaho, the rugged Hells Canyon on the Oregon–Idaho border and the rolling Palouse Hills of Washington, emptying into the Columbia River at the Tri-Cities in the Columbia Basin of Eastern Washington. The Snake River drainage basin encompasses parts of six U.S. states (Idaho, Washington, Oregon, Utah, Nevada, and Wyoming) and is known for its varied geologic history. The Snake River Plain was created by a volcanic hotspot which now lies underneath the Snake River headwaters in Yellowstone National Park. Gigantic glacial-retreat flooding episodes during the previous Ice Age carved out canyons, cliffs, and waterfalls along the middle and lower Snake Riv ...

Henrys Fork (Snake River)
Henrys Fork is a tributary river of the Snake River, approximately long, in southeastern Idaho in the United States. It is also referred to as the North Fork of the Snake River. Its drainage basin is , including its main tributary, the Teton River. Its mean annual discharge, as measured at river mile 9.2 (Henrys Fork near Rexburg) by the United States Geological Survey (USGS), is , with a maximum daily recorded flow of , and a minimum of . It is normally transcribed without an apostrophe. The river is named for Andrew Henry, who first entered the Snake River plateau in 1810. Employed by the Missouri Fur Company, he built Fort Henry on the upper Snake River, near modern St. Anthony, but abandoned this first American fur post west of the continental divide the following spring. Sources The river's source is at Big Springs and the Henrys Lake outlet (10 miles northwest of Big Springs). To the east is Targhee Pass, with Raynolds Pass to the northwest and Red Rock Pass to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
