Dragons Tail (Montana)
The Dragons Tail is an elevation ridge located in the Lewis Range, of Glacier National Park in the U.S. state of Montana. It is situated on the Continental Divide, on the border shared by Flathead County and Glacier County. Topographic relief is significant as the north aspect rises above Hidden Lake in one-half mile, and the west aspect rises nearly above Avalanche Lake in two miles. It can be seen from the Hidden Lake overlook along with its nearest higher neighbor, Bearhat Mountain, to the northwest. Climate Based on the Köppen climate classification, Dragons Tail is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers. Temperatures can drop below −10 °F with wind chill factors below −30 °F. Precipitation runoff from the west side of the ridge drains into creeks which empty into Lake McDonald, and the east side drains into the St. Mary River.

Bearhat Mountain
Bearhat Mountain () is located in the Lewis Range, Glacier National Park in the U.S. state of Montana. Bearhat Mountain is immediately west of Hidden Lake. The mountain was named after a Kootenai Native American, and was officially adopted by the U.S. Board on Geographic Names in 1932. Based on the Köppen climate classification, Bearhat Mountain 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, Bearhat Mountain 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 precambrian rocks thick, wide and long over younger rock of the cretaceous period.

Sedimentary Rock
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sperry Glacier
Sperry Glacier is a glacier on the north slopes of Gunsight Mountain west of the Continental Divide in Glacier National Park in the U.S. state of Montana. Although many geologic features of Glacier National Park were formed during the much longer period of glaciation ending over 10,000 years ago, Sperry Glacier — like all the glaciers in the park today — is a product of the recent Little Ice Age, the period of cooler average temperatures starting in about the 13th century and concluding in the mid-19th century. Once one of the largest glaciers in the park, the surface area of Sperry Glacier has retreated 75 percent since the mid-19th century. 2005 measurements of the surface area of the glacier resulted in an estimated area of , whereas the glacier is estimated to have covered an area of at the end of the Little Ice Age in the mid-19th century. The glacier lost almost 35 percent of its surface area between 1966 and 2005. The glacier is named for Lyman B. Sperry, a pro ...

Fusillade Mountain
Fusillade Mountain () is located in the Lewis Range, Glacier National Park in the U.S. state of Montana. Fusillade Mountain lies immediately north of Gunsight Lake at the western terminus of the St. Mary Valley and can be seen from the Going-to-the-Sun Road. The mountain was named by George Bird Grinnell in 1891, "as a satirical gesture at W. H. Seward and Henry L. Stimson for firing a futile volley at a group of goats on the side of this mountain". Geology Like the mountains in Glacier National Park, Fusillade 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 precambrian rocks thick, wide and long over younger rock of the cretaceous period.

Geology Of The Rocky Mountains
The geology of the Rocky Mountains is that of a discontinuous series of mountain ranges with distinct geological origins. Collectively these make up the Rocky Mountains, a mountain system that stretches from Northern British Columbia through central New Mexico and which is part of the great mountain system known as the North American Cordillera. The rocky cores of the mountain ranges are, in most places, formed of pieces of continental crust that are over one billion years old. In the south, an older mountain range was formed 300 million years ago, then eroded away. The rocks of that older range were reformed into the Rocky Mountains. The Rocky Mountains took shape during an intense period of plate tectonic activity that resulted in much of the rugged landscape of the western North America. The Laramide orogeny, about 80–55 million years ago, was the last of the three episodes and was responsible for raising the Rocky Mountains. Subsequent erosion by glaciers has created the ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards.
