Lewis Range
The Lewis Range is a mountain range located in the Rocky Mountains of northern Montana, United States and extreme southern Alberta, Canada. It was formed as a result of the Lewis Overthrust, a geologic thrust fault resulted in the overlying of younger Cretaceous rocks by older Proterozoic rocks. The range is located within Waterton Lakes National Park in Alberta, Canada and Glacier National Park and the Bob Marshall Wilderness Complex in Montana, United States. The highest peak is Mount Cleveland at . Geology Formed by the Lewis Overthrust beginning 170 million years ago, an enormous slab of Precambrian rocks 3 miles (4.8 km) thick, wide and long faulted and slid over newer rocks of the Cretaceous period. In this relatively rare occurrence, older rocks are now positioned above newer ones. Geography The Lewis Range is within Waterton Lakes National Park in Canada, and in Glacier National Park and the Bob Marshall Wilderness Complex located in Flathead and Lewis and ...

Mount Cleveland (Montana)
Mount Cleveland is the highest mountain in Glacier National Park, located in Montana, United States. It is also the highest point in the Lewis Range, which spans part of the northern portion of the park and extends into Canada. It is located approximately southeast of the southern end of Waterton Lake, and approximately south of the US–Canada border. The east side of the future national park was purchased by the federal government from the Blackfoot Confederacy in 1895 during the second term of President Grover Cleveland. According to the United States Board on Geographic Names, the mountain is named for the former president. While not of great absolute elevation (the mountain is more than lower than Granite Peak, the highest peak in Montana), Mount Cleveland is notable for its large, steep rise above local terrain. For example, its west flank rises over in less than ; the northwest face, the steepest on the mountain, rises in less than . The other faces show almost as mu ...

Mount Jackson (Montana)
Mount Jackson () is located in the Lewis Range, Glacier National Park in the U.S. state of Montana. Mount Jackson is the fourth tallest mountain in Glacier National Park and it is situated on the Continental Divide. Both the mountain and its namesake Jackson Glacier are easily seen from the Going-to-the-Sun Road. Harrison Glacier, the park's largest remaining glacier, is located on the mountain's southern flank. Based on the Köppen climate classification, Mount Jackson has an alpine climate characterized by long, usually very cold winters, and short, cool to mild summers. Temperatures can drop below −10 °F with wind chill factors below −30 °F. Geology Like other mountains in Glacier National Park, Mount Jackson is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was initially uplifted beginning 170 million years ago when the Lewis Overthrust fault pushed an enormous slab of pr ...

Landforms Of Flathead County, Montana
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Ranges Of Montana
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 ...

List Of Mountain Ranges In Montana
This is a list of mountain ranges in the state of Montana. Montana is the fourth largest state in the United States and is well known for its mountains. The name "Montana" means "mountainous" in Latin. Representative James Mitchell Ashley ( R-Ohio), suggested the name when legislation organizing the territory was passed by the United States Congress in 1864. Ashley noted that a mining camp in the Colorado Territory had already used the name, and Congress agreed to use the name for the new territory. According to the United States Board on Geographic Names, there are at least 100 named mountain ranges and sub-ranges in Montana. However, mountain ranges have no official boundaries, and there is no official list of mountain ranges in the state. List of mountain ranges The mountain ranges below are listed by name, county, coordinates, and average elevation as recorded by the U.S. Geological Survey. Sub-ranges are indented below the name of the primary range. Some of these ranges exte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Logan Pass
Logan Pass (elevation ) is located along the Continental Divide in Glacier National Park, in the U.S. state of Montana. It is the highest point on the Going-to-the-Sun Road. The pass is named after Major William R. Logan, the first superintendent of the park. The Logan Pass Visitor Center is open during the summer season just east of the pass. The pass is a popular starting point for hiking and backpacking trips. The most popular trail is the Highline Trail which heads north along the west side of the continental divide, through an area known as the Garden Wall, due to the proliferation of wildflowers which grow there during the summer. Just east of the pass, an area known as Big Drift often records over 100 feet (30 m) of snowfall, much of which has been pushed over the continental divide by the prevailing westerly winds during the winter. The pass is closed during the winter due to avalanche hazards and the virtual impossibility of keeping the Going-to-the-Sun Road open, yet is ...

Bob Marshall Wilderness
The Bob Marshall Wilderness Area is a congressionally-designated wilderness area located in Western Montana region of the United States. It is named after Bob Marshall (1901–1939), an early forester in the federal government, conservationist, and co-founder of The Wilderness Society. In the 1930s while working for the Forest Service, Marshall was largely responsible for designation of large areas to be preserved as roadless within lands administered by the Forest Service; he achieved this through promulgation of various regulations. Formally designated in 1964, the Bob Marshall Wilderness extends for 60 miles (95 km) along the Continental Divide and consists of 1,009,356 acres (4,085 km²). As directed by the Wilderness Act of 1964, "The Bob", as it is informally known, is to remain roadless. The only permanent structures here are some old ranger stations and horse bridges. "The Bob" is the fifth-largest wilderness in the lower 48 states (after the Death Valley Wilder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Wall (geology)
A Chinese wall or ethical wall is an information barrier protocol within an organization designed to prevent exchange of information or communication that could lead to conflicts of interest. For example, a Chinese wall may be established to separate people who make investments from those who are privy to confidential information that could improperly influence the investment decisions. Firms are generally required by law to safeguard insider information and ensure that improper trading does not occur. Etymology Bryan Garner's ''Dictionary of Modern Legal Usage'' states that the metaphor title "derives ''of course'' from the Great Wall of China",, italics added although an alternative explanation links the idea to the screen walls of Chinese internal architecture. The term was popularized in the United States following the stock market crash of 1929, when the U.S. government legislated information separation between investment bankers and brokerage firms, in order to limit the ...
