ORIGINAL TITLE: Les polygones de fente de gel de l’île Prince Patrick (Arctique Canadien – 76° lat. N.)
The author describes the variety of forms and structures of frost fissure polygons on an island in the Queen Elizabeth Archipelago. Under the present-day climate, polygons formed by wedges of ice, by wedges of mineral soil, and by wedges of sand and ice have developed simultaneously. Sections through several of these structures are described. The conditions determining which type of polygons has developed appear to be primarily the granulometry of the soil and its humidity during the summer.
