Brady Glacier is known for its beauty in the Fairweather Range of Alaska. Many people every year during the summer months visit the glaciers surrounding the gulf coast of Alaska to see their statuesque landforms. Brady Glacier is that of a serene landscape, but one of many glaciers that are retreating and becoming victim to ice calving. Geographers have been studying the interesting glaciations of Brady for centuries now. Three geographers, especially, are taking notice to the change in advance and retreat of the glacier. The location of Brady Glacier is significant to tourism because it is around other glaciers in Alaska and once one glacier starts to retreat, soon others will follow. Brady Glacier in the region of the North pacific Coast of Alaska is becoming a figure to ice calving and possible flooding in the surrounding land leading to the risk in tourism.

The physical geography of the North Pacific Coast is not the greatest attraction to tourists in some cases, but the land itself is the winning prize that attracts many to its coast. Much of the North Pacific coast is covered in mountainous terrains that give the land its beauty. The land is very rugged when approaching the mountains and, “is a land of dramatic coastal mountains cut by glacially eroded fiords and islands,” (Birdsall). The rough terrain gives transportation in and around the region in the north difficulties resulting in the limitation of accessibility to only “air and water,” (Birdsall). “Brady Glacier is the largest glacier in the Fairweather Range of the St. Elias Mountain in southeast Alaska,” (Drendochology to the ...

This is a report based on three days of observations and testing in the region known as the Peterborough drumlin field. It will address a variety of regional elements, such as climate, soil, vegetation, hydrology, geomorphology, and geology. A variety of sites located on the Canadian Shield, the zone of thick glacial deposits to the south, and the transition between them will be the focus of the report. It is supplemented with previous research on the region. September 8, 1999, day one of the field study involved an area of largely granite bedrock that is part of the Canadian Shield and is the most northern point of study (see Map 2). September 9, 1999, day two, involved three main areas of study: the Bridgenorth esker (Map 3), Mark S. Burnham Park (Map 4), and the Rice Lake drumlin (Map 6). These sites are in areas of thick glacial deposits. September 10, 1999, day three, involved studying the Warsaw Caves (see Map 5) as a transition zone between Precambrian Shield rock to the north and Paleozoic rock to the south. A general map of the entire study region is provided by Map 1.

On September 20th, 2002, a disaster struck unprepared villages in North Ossetia, Russia. Colossal debris flow resulting from the complete detachment of the Kolka (Evans et al, 2009; Kotlyakov et al, 2004). Glacier travelled at extreme velocities reaching a distance of about 20km from the glacial bed down the Genaldon valley to Kamadon (Kotlyakov et al, 2004). A mudflow travelled an additional 15km stopping a few kilometers short of Gisel (Haeberli et al, 2004). The slide claimed a total of 125 lives directly, while outburts of newly formed lakes dammed by debris sediment threatened local villages with floods and additional losses (Kotyakov et al, 2004). The catastrophic acceleration and complete ejection of the valley glacier from it’s bed is unique to this event and has not been documented elsewhere (Chernomorets, 2007). The mechanism of this hazard involves a complex interaction between climatic and unique geological conditions of the area. The 2002 disaster has spurred a large amount of research into glacial associated natural hazards, which have provided options of improved preventative measures that will reduce losses in future events.
The foundation of the Great Lakes began around three billion years ago, which is known as the Precambrian Era. The Precambrian Era contains numerous ecological events, which consists of volcanic activity to erosion to the mountains and hills seen today being formed. Then during the Pleistocene Epoch or known as the “Ice Age, occurred between 1.6 million and 10,000 years ago. At least four times during the Pleistocene Epoch, large masses of ice advanced and retreated over the surface of what is now North America. As the glaciers advanced, giant sheets of ice flowed across the land, leveling mountains and carving out massive ...

In the findings by Thompson, Brechera, Mosley-Thompson, Hardy, and B. G. Mark, they discovered that “of the ice cover present in 1912, 85% has disappeared and 26% of that present in 2000 is now gone”. They traced the receding ice back to the early 20th century, beginning in 1912, where “summit ice cover (area extent) decreased ~1% per year from 1912 to 1953 and ~...
One of the most striking features in Glacier National Park is the color banding. This feature can be seen in nearly every mountain within the park as they are composed of different layers of rocks and colors. The rock strata are mainly composed of sedimentary rocks limestones, shales, sandstones, and lightly metamorphosed rocks (Dyson,1957). These rocks all belong to a single large unit known as the Belt series. The rocks are very unusual in that they were deposited in late in the Precambrian between 1600 and 800 million years ago and are relatively undeformed and only lightly metamorphosed (Alt, 1983). The rocks can be spotted throughout the large area of western Montana, northern Idaho, and southern British Columbia. The formation of the Belt Supergroup started during the Proterozoic era as a long narrow section of North America extending from the Arctic Ocean southward which slowly sank to form a large sea-filled trough also known as a geosyncline (Dyson, 1957). Streams from nearby lands carried muds and sands into the sea almost completely filling it. These muds were eventually compressed into shales, some limestones, and sands into sandstones. Many of the rocks in this series have very distinct features that give a clue about their origin, features suc...
