Madison River
The Madison River is a headwater tributary of the Missouri River, approximately 183 miles (295 km) long, in Wyoming and Montana. Its confluence with the Jefferson and Gallatin rivers near Three Forks, Montana forms the Missouri River. The Madison rises in Teton County in northwestern Wyoming at the confluence of the Firehole and Gibbon rivers, a location in Yellowstone National Park called ''Madison Junction''. It first flows west, then north through the mountains of southwestern Montana to join the Jefferson and the Gallatin rivers at Three Forks. The Missouri River Headwaters State Park is located on the Madison at Three Forks. In its upper reaches in Gallatin County, Montana, the Hebgen Dam forms Hebgen Lake. In its middle reaches in Madison County, Montana, the Madison Dam forms Ennis Lake and provides hydroelectric power. In 1959, the 1959 Hebgen Lake earthquake formed Quake Lake just downstream from Hebgen Dam. Downstream from Ennis, the Madison flows through B ...

Bear Trap Canyon
Bears are carnivoran mammals of the family Ursidae. They are classified as caniforms, or doglike carnivorans. Although only eight species of bears are extant, they are widespread, appearing in a wide variety of habitats throughout the Northern Hemisphere and partially in the Southern Hemisphere. Bears are found on the continents of North America, South America, Europe, and Asia. Common characteristics of modern bears include large bodies with stocky legs, long snouts, small rounded ears, shaggy hair, plantigrade paws with five nonretractile claws, and short tails. While the polar bear is mostly carnivorous, and the giant panda feeds almost entirely on bamboo, the remaining six species are omnivorous with varied diets. With the exception of courting individuals and mothers with their young, bears are typically solitary animals. They may be diurnal or nocturnal and have an excellent sense of smell. Despite their heavy build and awkward gait, they are adept runners, cli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gallatin County, Montana
Gallatin County is located in the U.S. state of Montana. With its county seat in Bozeman, it is the second-most populous county in Montana, with a population of 118,960 in the 2020 Census. The county's prominent geographical features are the Bridger mountains in the north, and the Gallatin mountains and Gallatin River in the south, named by Meriwether Lewis in 1805 for Albert Gallatin, the United States Treasury Secretary who formulated the Lewis and Clark Expedition. At the southern end of the county, West Yellowstone's entrance into Yellowstone National Park accounts for around half of all park visitors. Big Sky Resort, one of the largest ski resorts in the United States, lies in Gallatin and neighboring Madison counties, midway between Bozeman and West Yellowstone. History During the territorial era, a small patch of land known as " Lost Dakota" existed as a remote exclave of Dakota Territory until it was transferred to Gallatin County, Montana Territory, in 1873. ...

United States Secretary Of State
The United States secretary of state is a member of the executive branch of the federal government of the United States and the head of the U.S. Department of State. The office holder is one of the highest ranking members of the president's Cabinet, and ranks the first in the U.S. presidential line of succession among Cabinet secretaries. Created in 1789 with Thomas Jefferson as its first office holder, the secretary of state represents the United States to foreign countries, and is therefore considered analogous to a foreign minister in other countries. The secretary of state is nominated by the president of the United States and, following a confirmation hearing before the Senate Committee on Foreign Relations, is confirmed by the United States Senate. The secretary of state, along with the secretary of the treasury, secretary of defense, and attorney general, are generally regarded as the four most crucial Cabinet members because of the importance of their respective depa ...

Lee Metcalf Wilderness
The Lee Metcalf Wilderness is located in the northern Rocky Mountains in the U.S. state of Montana. Created by an act of Congress in 1983, this rugged alpine wilderness is divided into four separated parcels typified by complex mountain topography: Bear Trap Canyon unit, Spanish Peaks unit, Taylor-Hilgard unit, and Monument Mountains unit. The Bear Trap Canyon unit was the first designated wilderness area to be managed by the Bureau of Land Management (an agency within the Department of the Interior), and comprises a region of canyonlands adjacent to the Madison River. The other three sections of the wilderness are jointly managed by Beaverhead-Deerlodge and Gallatin National Forests, both of which are a part of the Department of Agriculture. The wilderness was named after the late Montana congressman Lee Metcalf. The portion of the wilderness within Gallatin National Forest is also within the Greater Yellowstone Ecosystem and borders Yellowstone National Park. U.S. wilderness ...

Whitewater Kayaking
Whitewater kayaking is an adventure sport where a river is navigated in a decked kayak. Whitewater kayaking includes several styles. River running; where the paddler follows a river and paddles rapids as they travel. Creeking usually involving smaller, steeper, and more technical waterways. Creek boats tend to be short but high volume to allow for manoeuvrability while maintaining buoyancy. Slalom requires paddlers to navigate through "gates" (coloured poles hanging above the river). Slalom is the only whitewater event to be in the Olympics. Play boating involves staying on one feature of the river and is more artistic than the others. Squirt boating uses low-volume boats (usually made specifically for the paddler) to perform special moves in whitewater features. History Paddling on rivers, lakes and oceans is as old as the Stone Age. The raft, the catamaran, the canoe and the kayak evolved depending on the needs and environment of the indigenous peoples in different parts o ...

Quake Lake
Quake Lake (officially Earthquake Lake) is a lake in the western United States, on the Madison River in southwestern Montana. It was created after an earthquake struck on August 17, 1959, with 28 fatalities. Northwest of West Yellowstone, Quake Lake is in length with a maximum depth of . U.S. Route 287 follows the lake and offers glimpses of the effects of the earthquake and landslide, and a visitor center is just off the road. The lake is mostly within Gallatin National Forest. Earthquake The earthquake measured 7.5 on the Richter magnitude scale (revised by USGS to 7.3) and caused an 80-million ton landslide, which formed a landslide dam on the Madison River. The earthquake was the most powerful to hit the state of Montana in historic times. The landslide traveled down the north flank of Sheep Mountain, at an estimated , killing 28 people who were camping along the shores of Hebgen Lake and downstream along the Madison River. Upstream the faulting caused by the earth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1959 Hebgen Lake Earthquake
The 1959 Hebgen Lake earthquake (also known as the 1959 Yellowstone earthquake) occurred in the western United States on August 17 at 11:37 pm ( MST) in southwestern Montana. The earthquake measured 7.2 on the moment magnitude scale, caused a huge landslide, resulted in over 28 fatalities and left $11 million (equivalent to $ million in ) in damage. The slide blocked the flow of the Madison River, resulting in the creation of Quake Lake. Significant effects of the earthquake were also felt in nearby Idaho and Wyoming, and lesser effects as far away as Puerto Rico and Hawaii. The 1959 quake was the strongest and deadliest earthquake to hit Montana, the second being the 1935–36 Helena earthquakes that left four people dead. It also caused the worst landslides in the northwestern United States since 1927. Earthquake The earthquake occurred at 11:37 p.m. (MST) with a magnitude of 7.2 . The U.S. Weather Bureau reported that the quake lasted 30–40 seconds. During t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric Power
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Ennis Lake
Madison Dam is a hydroelectric dam on the Madison River in Madison County, Montana, in the southwestern part of the state. The timber-crib dam was constructed in 1906 as a replacement for a similar 1901 dam and powerhouse on the same site. The dam is high and long at its crest, placed into the narrows of Bear Trap Canyon. As one of eight PPL Montana hydro projects, it has a generating capacity of in a run-of-the-river configuration. Montana Power Company acquired the dam in 1912 as part of a merger, PPL Corporation purchased it in 1997 and sold it to NorthWestern Corporation NorthWestern Corporation owns NorthWestern Energy, a utility company that serves South Dakota, Nebraska, and Montana that is based in Sioux Falls. , the company serves approximately 718,000 customers.
