West Antarcticas ground is almost entirely below sea level. plural crevasses. The inflexible upper portion may split as it moves over the changing landscape.Crevasses also form when different parts of a glacier move at different speeds. These cracks in the surface of the ice shelf are an easily identifiable marker of areas of high stress within the ice flow. Lastly, crevasses are interesting because sometimes fascinating things fall into them. In this. Crevasses can range from a few to hundreds of meters wide and deep.

In such cases recovery was a long and skilled manoeuvre and often seemed impossible, but our engineers always managed to figure a way to haul our vehicles to safety." Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. These are the hidden gems in the secret world of crevasses. Feel free to email your question to juliansantarctica@gmail.com, and I will try to answer it in the next blog entry! If you need to flag this entry as abusive. They most often occur where the flow of a glacier increases, like in a steep deepening valley, and are thus oriented perpendicular to direction of flow. They indicate past flow conditions, or even the locations of abandoned shear margins, where there used to be a boundary between ice streams moving at differing speeds. A noted local climber fell to his death Tuesday in a crevasse high on Mount Rainier's Emmons Glacier.
