Compactibility of newly fallen snow in Eastern Canada

The critical density of newly fallen snow was measured during the 1956-57 winter season attwo stations: Montrcal Road Laboratories of the National Research Council, Ottawa, and the Universityof New Brunswick, Fredericton, New Brunswick. The relative compacted density or compactibility ofnewly fallen...
