The distribution and thickness of icy permafrost in northeastern British Columbia
The depth of icy permafrost below the active layer in northeastern British Columbia has been mapped in subparallel north-northwest and south-southeast zones, the thickest permafrost occurring in organic terrain near the Alberta border. Across the Rocky Mountain foothills in the west of the study are...
