Résumé du colloque

Extensive ground ice mantled by up to 10 feet of gravel and sand occurs in the Tuktoyaktuk settlement area. An examination of this phenomenon and of numerous natural ice houses has revealed that the pure blue ice or ice interbedded with sand may underly the whole peninsula to a depth of at least 30 feet, while the total thickness of ice is unknown. This feature represents important problems from a constructional point of view. At the same time, it could have a practical application as a huge cold storage area. The temperature of the ice, recorded during investigation on July 21, 1961, was from 22°F to 26°F, while the air temperature three feet above the ice surface was from 27°F - 31°F. The possibility of the origin of this ice is discussed.
