Abstract
Inactive stone polygons and stripes, together with blockfields, exist on the summit of Mont Jacques-Cartier, one of the highest elevations in eastern Canada. Permafrost and tundra conditions prevail today. The polygons are thought to have resulted from thermal contraction cracking combined with the lateral movement of near-surface material towards the periphery of the polygons. Their age of formation is unclear. If they formed in pre-Late Wisconsinan time, their preservation implies that the ice sheet was cold-based and non-erosive. If of more recent origin, they must have formed in the relatively short period after the summit became ice-free, glacier ice was restricted to the surrounding valleys, and before the climate warmed in the early Holocene.
