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 ...
A crevasse may be as deep as 45 m (148 ft) and as wide as 20 m (66 ft). [11] A crevasse may be covered, but not necessarily filled, by a snow bridge made of the previous years' accumulation and snow drifts. The result is that crevasses are rendered invisible, and extremely dangerous to anyone attempting to traverse a glacier. [12]
A bergschrund is distinct from a randkluft, 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
The Getty vocabularies can be used in three ways: at the data entry stage, by catalogers or indexers who are describing works of art, architecture, material culture, archival materials, visual surrogates, or bibliographic materials; as knowledge bases, providing information for researchers; and as search assistants to enhance end-user access to online resources.

WordNet is a lexical database of semantic relations between words that links words into semantic relations including synonyms, hyponyms, and meronyms. The synonyms are grouped into synsets with short definitions and usage examples. It can thus be seen as a combination and extension of a dictionary and thesaurus.
Conceiving that such a compilation might help to supply my own deficiencies, I had, in the year 1805, completed a classed catalogue of words on a small scale, but on the same principle, and nearly in the same form, as the Thesaurus now published. [4] Roget's Thesaurus is composed of six primary classes. [5]
