This GIS dataset is a Yukon-wide compilation of surficial geology polygons derived from 15 published and unpublished 1:20,000 and 1:25,000 scale surficial geology maps produced by the Yukon Geological Survey and City of Whitehorse. All polygon map unit labels have been converted to standardized map unit labels, based on the British Columbia terrain classification system. Standardized attributes include: surficial material, texture, age, surface expression and geomorphological processes.
