A bergschrund is distinct from a randkluft (also called rimaye), which is a crevasse with one side formed by rock. The randkluft arises in part from the melting of the ice due to the presence of the warmer rock face. [2] However, a randkluft is sometimes called a bergschrund. [3] The French word rimaye encompasses both randklufts and bergschrunds.
Transverse crevasses, Chugach State Park, Alaska. A crevasse is a deep crack that forms in a glacier or ice sheet. 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. The resulting intensity of the shear ...
"Red Couloir" in the Polish Tatra Mountains. A couloir may be a seam, scar, or fissure, or vertical crevasse in an otherwise solid mountain mass. Though often hemmed in by sheer cliff walls, couloirs may also be less well-defined, and may often simply be a line of broken talus or scree ascending the mountainside and bordered by trees, rocks or other natural features.
They can be up to 10 meters wide and are typically found on ice sheets and flat areas of a glacier in a region of transverse crevasses. Moulins can reach the bottom of the glacier, hundreds of meters deep, [3] [4] [5] or may only reach the depth of common crevasse formation (about 10–40 m) where the stream flows englacially. [6]
French orthography encompasses the spelling and punctuation of the French language.It is based on a combination of phonemic and historical principles. The spelling of words is largely based on the pronunciation of Old French c. 1100 –1200 AD, and has stayed more or less the same since then, despite enormous changes to the pronunciation of the language in the intervening years.
The spelling of some words was changed to keep the pronunciation as close to the original as possible (e.g. leaven). In other cases, the French spelling was kept, leading to a totally different pronunciation than in French (e.g. leopard, levee). [3]
