Snake River Canyon (Wyoming)
The Snake River Canyon (also known as the ''Grand Canyon'') is formed by the Snake River in western Wyoming, United States, south of Jackson Hole. At the southern end of this canyon is the town of Alpine, Wyoming where the Snake River meets the Greys River and the Salt River at Palisades Reservoir on the Wyoming-Idaho border. It is a popular destination for rafting trips and is known for having some of the best white-water rafting in the United States. Running through the canyon is US 89. Geology The Snake River cuts through a fold and thrust belt on its way from Hoback, Wyoming to Alpine, Wyoming. The North American Plate has pushed against the Farallon Plate The Farallon Plate was an ancient oceanic plate. It formed one of the three main plates of Panthalassa, alongside the Phoenix Plate and Izanagi Plate, which were connected by a triple junction. The Farallon Plate began subducting under the west ... to create many geologic features including the folds and thrusts v ...

Wyoming
Wyoming () is a state in the Mountain West subregion of the Western United States. It is bordered by Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the south. With a population of 576,851 in the 2020 United States census, Wyoming is the least populous state despite being the 10th largest by area, with the second-lowest population density after Alaska.

It is drier and windier than the rest of the country, being split between semi-arid and continental climates with greater temperature extremes. Almost half of the land in Wyoming is owned by the federal government, generally protected for public uses. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Snake River Canyon WY1
Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, altho ...

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 ...

Jackson Hole
Jackson Hole (originally called Jackson's Hole by mountain men) is a valley between the Gros Ventre and Teton mountain ranges in the U.S. state of Wyoming, near the border with Idaho, in Teton County, one of the richest counties in the United States. The term "hole" was used by early trappers, or mountain men, as a term for a large mountain valley. These low-lying valleys, surrounded by mountains and containing rivers and streams, are good habitat for beavers and other fur-bearing animals. Jackson Hole is 55 miles (89 km) long by 6-to-13 miles (10-to-21 km) wide and is a graben valley with an average elevation of 6,800 ft (2,100 m), its lowest point being near the southern park boundary at 6,350 ft (1,940 m). History The town of Jackson was named in late 1893 by Margaret Simpson, who, at the time, was receiving mail at her home as there was no post office. She named the area in order for easterners to be able to forward mail west. Jackson, which became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpine, Wyoming
Alpine is a town in Lincoln County, Wyoming, United States. The population was 828 at the 2010 census. Geography Alpine is located at the southern end of the Snake River Canyon where the Snake River enters Palisades Reservoir. The town is also known as Alpine Junction since it marks the point where U.S. routes 26 and 89 turn in opposite directions. The two routes run concurrently through the Snake River Canyon from Jackson. In Alpine, Route 89 turns south toward Afton, while Route 26 turns north and follows the edge of Palisades Reservoir to Swan Valley, Idaho. Three rivers come together in the vicinity of Alpine: the Snake, the Salt, and the Greys - the Greys merges with the Snake right at the high water mark of the reservoir, while the Salt discharges directly into the reservoir nearby unless the reservoir is exceptional low. According to the United States Census Bureau, the town has a total area of , all land. Climate This climatic region is typified by large season ...

Idaho
Idaho ( ) is a state in the Pacific Northwest region of the Western United States. To the north, it shares a small portion of the Canada–United States border with the province of British Columbia. It borders the states of Montana and Wyoming to the east, Nevada and Utah to the south, and Washington and Oregon to the west. The state's capital and largest city is Boise. With an area of , Idaho is the 14th largest state by land area, but with a population of approximately 1.8 million, it ranks as the 13th least populous and the 7th least densely populated of the 50 U.S. states. For thousands of years, and prior to European colonization, Idaho has been inhabited by native peoples.

White-water Rafting
Rafting and whitewater rafting are recreational outdoor activities which use an inflatable raft to navigate a river or other body of water. This is often done on whitewater or different degrees of rough water. Dealing with risk is often a part of the experience. This activity as an adventure sport has become popular since the 1950s, if not earlier, evolving from individuals paddling to rafts with double-bladed paddles or oars to multi-person rafts propelled by single-bladed paddles and steered by a person at the stern, or by the use of oars. Rafting on certain sections of rivers is considered an extreme sport and can be fatal, while other sections are not so extreme or difficult. Rafting is also a competitive sport practiced around the world which culminates in a world rafting championship event between the participating nations. The International Rafting Federation, often referred to as the IRF, is the worldwide body which oversees all aspects of the sport. Equip ...

Fold And Thrust Belt
A fold and thrust belt (FTB) is a series of mountainous foothills adjacent to an orogenic belt, which forms due to contractional tectonics. Fold and thrust belts commonly form in the forelands adjacent to major orogens as deformation propagates outwards. Fold and thrust belts usually comprise both folds and thrust fault A thrust fault is a break in the Earth's crust, across which older rocks are pushed above younger rocks. Thrust geometry and nomenclature Reverse faults A thrust fault is a type of reverse fault that has a dip of 45 degrees or less. If ...s, commonly interrelated. They are commonly also known as thrust-and-fold belts, or simply thrust-fold belts. Geometry Fold and thrust belts are formed of a series of sub-parallel thrust sheets, separated by major thrust faults. As the total shortening increases in a fold and thrust belt, the belt propagates into its foreland. New thrusts develop at the front of the belt, folding the older thrusts that have become ...
