| Title: | Rock blisters and other frost-heaved landforms in the Bernard Harbour area, District of Mackenzie, N.W.T. / Denis A. St-Onge, Isabelle McMartin, Ron Avery. |
| Author(s): | St-Onge, Denis A. McMartin, Isabelle. Avery, Ron. |
| Date: | 1989. |
| Publisher: | Ottawa: Geological Survey of Canada |
| In: | Geological Survey of Canada. Paper. (1989.), Vol. 89-1D (1989) |
| Abstract: | Blisters (on dolomite) are 1 to 3 m high and 2 to 5 m in diameter, resembling miniature pingos. Related forms in shaly sandstone are 2 to 3 m deep trenches in regular grid pattern, with cells 50 to 120 m wide. Evidence suggests all frost-heaved features date from early postglacial. |
