Teewinot Mountain
Teewinot Mountain () is the sixth highest peak in the Teton Range, Grand Teton National Park, Wyoming. The name of the mountain is derived from the Shoshone Native American word meaning "many pinnacles". The peak is northeast of the Grand Teton, and the two are separated from one another by the Teton Glacier and Mount Owen. Teewinot Mountain rises more than above Jenny Lake. The long Teton Range is the youngest mountain chain in the Rocky Mountains, and began their uplift 9 million years ago, during the Miocene. Several periods of glaciation have carved Teewinot Mountain and the other peaks of the range into their current shapes. Broken Falls is one of the tallest cascades in Grand Teton National Park and descends down the eastern slopes of Teewinot Mountain. Climbing Teewinot Mountain is most easily ascended via the eastern face, which finishes with a somewhat exposed Class 4 scramble to the tiny summit. An unmarked climbers' trail, known as the Apex Trail, leads most of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Teton National Park
Grand Teton National Park is an American national park in northwestern Wyoming. At approximately , the park includes the major peaks of the Teton Range as well as most of the northern sections of the valley known as Jackson Hole. Grand Teton National Park is only south of Yellowstone National Park, to which it is connected by the National Park Service–managed John D. Rockefeller Jr. Memorial Parkway. Along with surrounding national forests, these three protected areas constitute the almost Greater Yellowstone Ecosystem, one of the world's largest intact mid-latitude temperate ecosystems. The human history of the Grand Teton region dates back at least 11,000 years when the first nomadic hunter-gatherer Paleo-Indians began migrating into the region during warmer months to pursue food and supplies. In the early 19th century, the first white explorers encountered the eastern Shoshone natives. Between 1810 and 1840, the region attracted fur trading companies that vied fo ...

Jenny Lake
Jenny Lake is located in Grand Teton National Park in the U.S. state of Wyoming. The lake was formed approximately 12,000 years ago by glaciers pushing rock debris which carved Cascade Canyon during the last glacial maximum, forming a terminal moraine which now impounds the lake. The lake is estimated to be deep and encompasses . Jenny Lake is considered to be a major focal point in Grand Teton National Park, with many hiking trails, scenic boat rides, and quick access to the major climbing routes onto the tallest peaks of the Teton Range. Jenny and Jackson Lakes are the only lakes in Grand Teton National Park where motorboats are permitted; both lakes have scenic tours available. A 2005 study of the water quality of the lakes in Grand Teton National Park indicated that all the lakes in the park were still considered pristine and that they had not been impacted by air or water pollution. Jenny Lake is a starting point for many day and overnight hiking trips. The Jenny Lake Tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Grand Teton National Park
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 ...

Geology Of The Grand Teton Area
The geology of the Grand Teton area consists of some of the oldest rocks and one of the youngest mountain ranges in North America. The Teton Range, partly located in Grand Teton National Park, started to grow some 9 million years ago. An older feature, Jackson Hole, is a basin that sits aside the range. The 2.5 billion year old metamorphic rocks that make up the east face of the Tetons are marine in origin and include some volcanic deposits. These same rocks are today buried deep inside Jackson Hole. Paleozoic rocks were deposited in warm shallow seas while Mesozoic deposition transitioned back and forth from marine to non-marine sediments with the Cretaceous Seaway periodically covering the area late in that era. Precambrian deposition, metamorphism, and intrusion Perhaps 3 billion years ago in Precambrian time, sand, limey ooze, silt and clay were deposited in a marine trough (accurate dating is not possible, due to subsequent partial recrystallization of the resulting rock) ...

Yosemite Decimal System
The Yosemite Decimal System (YDS) is a three-part system used for rating the difficulty of walks, hikes, and climbs, primarily used by mountaineers in the United States and Canada. It was first devised by members of the Sierra Club in Southern California in the 1950s as a refinement of earlier systems, particularly those developed in Yosemite Valley, and quickly spread throughout North America. Description The class 5 portion of the class scale is primarily a rock climbing classification system, while classes 1–2 are used mainly in hiking and trail running. Class 3 describes easy and moderate climbing (i.e. scrambling), with varying amounts of exposure (length of a possible fall). Class 4 is an "in-between" rating that describes a very exposed scramble, corresponding roughly to the IFAS classification of PD+. Climbers, specifically those involved with technical class 5 climbing, often abbreviate "class 3" and "class 4" to "3rd" and "4th" respectively. Originally the system was ...

Glaciation
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of the Trench, or in the northeastern foothills of the Brooks Range/ British Mountains that face the Beaufort Sea coasts between the Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west. The ...

Mount Owen (Wyoming)
Mount Owen () is the second highest peak in the Teton Range, Grand Teton National Park in the U.S. state of Wyoming. The peak is named after William O. Owen, who organized the first documented ascent of the Grand Teton in 1898. Mount Owen is part of the Cathedral Group of high Teton peaks, a collection of peaks in the central section of the range that are particularly rugged. The long Teton Range is the youngest mountain chain in the Rocky Mountains, and began its uplift 9 million years ago, during the Miocene. Several periods of glaciation have carved Mount Owen and the other peaks of the range into their current shapes. Valhalla Canyon is situated on the west slopes of Mount Owen. Climbing After two failed attempts in 1927 and one in 1928, Mount Owen was first climbed in 1930, and was one of the last of the major Teton peaks to be climbed. Numerous routes have been explored, ranging in difficulty from Class 5.1 to 5.10 See also * Geology of the Grand Teton area Refe ...
