Jackson Lake Dam
Jackson Lake Dam is a concrete and earth-fill dam in the western United States, at the outlet of Jackson Lake in northwestern Wyoming. The lake and dam are situated within Grand Teton National Park in Teton County. The Snake River emerges from the dam and flows about through Wyoming, Idaho, Oregon, and Washington to its mouth on the Columbia River in eastern Washington. The chief purpose of the dam is to provide water storage for irrigation in the Snake River basin in the state of Idaho as part of the Minidoka Project. Jackson Lake is a natural lake, but its depth was increased by the dam to provide water storage. History The first Jackson Lake Dam was a log-crib dam constructed in 1906–07 across the outlet of Jackson Lake, a natural lake. That dam raised the lake level by , but the dam failed in 1910. A new concrete and earthen dam was constructed in stages between 1911 raising the maximum lake level to above the lake's natural elevation, providing a storage capacity of . ...

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 (state), Washington, emptying into the Columbia River at the Tri-Cities, Washington, 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 (geology), hotspot which now lies underneath the Snake River headwaters in Yellowstone National Park.

1983 Borah Peak Earthquake
The 1983 Borah Peak earthquake occurred on October 28, at in the western United States, in the Lost River Range at Borah Peak in central Idaho. The shock measured 6.9 on the moment magnitude scale and had a maximum Mercalli intensity of IX (''Violent''). It was the most violent earthquake in the lower 48 states in over 24 years, since the 1959 Hebgen Lake earthquake in nearby southwestern Earthquake The Friday morning earthquake was caused by a slip on the preexisting Lost River Fault. The event is the largest and most significant to strike in the state of Idaho. Two children were killed by falling masonry while walking to school in about northeast of Boise, the state capital. Twelve-and-a-half million dollars in damage took place in the Challis-Mackay region in Custer County. As a result of extreme surface faulting, a maximum Mercalli intensity of IX (''Violent'') was decided upon, while vibrational damage was at a Mercalli intensity of VI (''Strong'') to VII (''Very stron ...

Richter Magnitude Scale
The Richter scale —also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale—is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". This was later revised and renamed the local magnitude scale, denoted as ML or . Because of various shortcomings of the original scale, most seismological authorities now use other similar scales such as the moment magnitude scale () to report earthquake magnitudes, but much of the news media still erroneously refers to these as "Richter" magnitudes. All magnitude scales retain the logarithmic character of the original and are scaled to have roughly comparable numeric values (typically in the middle of the scale). Due to the variance in earthquakes, it is essential to understand the Richter scale uses logarithms simply to make the measurements manageable (i.e., a magnitude 3 quake factors ...

Ashton, Idaho
Ashton is a city in Fremont County, Idaho, United States. The population was 1,127 at the 2010 census, and it is part of the Rexburg Micropolitan Statistical Area. The district is noted for seed potato production and bills itself as the world's largest seed potato growing area. History Railroad In 1900, the Union Pacific Railroad, under the careful watch of the Oregon Short Line (OSL) and St. Anthony Railroad Company, brought the railroad into the Upper Snake River Valley from Idaho Falls to St. Anthony, Idaho, southwest of what became Ashton. The venture had considerable local support and official support from the LDS Church. Following successful construction and operation of the St. Anthony Railroad, Union Pacific, under the careful watch of the OSL and the Yellowstone Park Railroad Company, began plans for another railroad from St. Anthony to the Madison River entrance of Yellowstone National Park or to what is now known as West Yellowstone. For years, Union Pacific wanted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grassy Lake Dam
Grassy Lake Dam is a small dam operated by the U.S. Bureau of Reclamation in Teton County, Wyoming, immediately to the south of Yellowstone National Park. The dam lies in a corridor of Bridger-Teton National Forest that runs between Yellowstone and Grand Teton National Parks. The dam structure and outlets are within a few hundred feet of the south boundary of Yellowstone. The zoned earthfill dam was built between 1937 and 1939 as part of the Minidoka Project, which provides water to irrigate farmland in Idaho's Snake River Plain. The dam provides only water storage, impounding . Given the small catchment area of Grassy Creek, inflow is augmented by a ditch that moves water from Cascade Creek into the reservoir. Bechler Meadows dam proposals The Grassy Lake Dam and the Island Park Reservoir in Idaho were the outcome of an ambitious plan to use the abundant waters of Yellowstone National Park for irrigation in Idaho, Montana and Wyoming. A variety of projects were proposed star ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yellowstone National Park
Yellowstone National Park is an American national park located in the western United States, largely in the northwest corner of Wyoming and extending into Montana and Idaho. It was established by the 42nd U.S. Congress with the Yellowstone National Park Protection Act and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially the Old Faithful geyser, one of its most popular. While it represents many types of biomes, the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion. While Native Americans have lived in the Yellowstone region for at least 11,000 years, aside from visits by mountain men during the early-to-mid-19th century, organized exploration did not begin until the late 1860s. Management and control of the park ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiquities Act
The Antiquities Act of 1906 (, , ), is an act that was passed by the United States Congress and signed into law by Theodore Roosevelt on June 8, 1906. This law gives the President of the United States the authority to, by presidential proclamation, create national monuments from federal lands to protect significant natural, cultural, or scientific features. The Act has been used more than a hundred times since its passage. History The Antiquities Act was signed into law by President Theodore Roosevelt during his second term in office. The act resulted from concerns about protecting mostly prehistoric Native American ruins and artifacts -- collectively termed "antiquities" -- on federal lands in the West, such as at Chaco Canyon, New Mexico. Removal of artifacts from these lands by private collectors, "pot hunters," had become a serious problem by the end of the 19th century. In 1902, Iowa Congressman John F. Lacey, who chaired the House Committee on the Public Lands, trave ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jackson Hole National Monument
On March 15, 1943, Franklin D. Roosevelt signed Presidential Proclamation 2578 establishing a large swath of land east of the Teton National Park as a national monument.Booklet of the Congressional hearing to abolish the Jackson Hole national Monument, 1A, Booklets, Burt Family Collection, 7570, American Heritage Center, University of Wyoming. The area of land covered 221,610 acres. The majority of the land was National Forest, but 32,117 acres of the monument were donated by John D. Rockefeller, Jr., and 17,000 acres were privately owned ranches. This proclamation incited a controversy in Teton County that caused immediate pushback from western congressmen who saw the act as a violation of state sovereignty.Box 1A, Burt Family Papers, 1911-1970, 07570, American Heritage Center, University of Wyoming Background Within Teton County, private interests regularly fought for their right to use natural resources available to them which worried conservationist parties and started a ch ...

Teton Range
The Teton Range is a mountain range of the Rocky Mountains in North America. It extends for approximately in a north–south direction through the U.S. state of Wyoming, east of the Idaho state line. It is south of Yellowstone National Park and most of the east side of the range is within Grand Teton National Park. One theory says the early French voyageurs named the range ' ("the three nipples") after the breast-like shapes of its peaks. Another theory says the range is named for the Teton Sioux (from Thítȟuŋwaŋ), also known as the Lakota people.Ullrich, Jan. (2008). ''New Lakota Dictionary''. Lakota Language Consortium. It is likely that the local Shoshone people once called the whole range ', meaning "many pinnacles". The principal summits of the central massif, sometimes referred to as the Cathedral Group, are Grand Teton (), Mount Owen (), Teewinot (), Middle Teton () and South Teton (). Other peaks in the range include Mount Moran (), Mount Wister (), Buck Mounta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
