Rupture of an ice mound near Cape Dorset, N.W.T.
An ice feature comprising ice blocks ranging from football size to 0.6 m cubes to 1.2 m X 3.6 m X 0.6 m slabs was observed on the surface of a frozen lake. Site investigations revealed the source of the blocks to be an ice mound that had formed along the shore of the lake. A model, supported by loca...

| Summary: | An ice feature comprising ice blocks ranging from football size to 0.6 m cubes to 1.2 m X 3.6 m X 0.6 m slabs was observed on the surface of a frozen lake. Site investigations revealed the source of the blocks to be an ice mound that had formed along the shore of the lake. A model, supported by local meteorological, geological, and hydrological information, is proposed to explain the formation of the ice mound and its subsequent rupture. Une formation de glace comprenant des blocs variant de la dimension d'un ballon de football à des cubes de 0.6 m de coté et à des dalles de 1.2 m X 3.6 m X 0.6 m a été observée à la surface d'un lac gelé. Les travaux de reconnaissances ont révélé que l'origine de ces blocs était un rempart de glace qui s'était formé sur la rive du lac. Un modèle, fondé sur les données météorologiques, géologiques et hydrologiques locales, est proposé pour expliquer la formation du rempart de glace et sa rupture subséquente.
