Record #96889:

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.

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.
