Aggregate potential was analyzed and classified for a four-kilometre corridor centred on Yukon highways and in a 20 km radius around Yukon communities excluding Whitehorse to support maintenance and development of Yukon infrastructure. Aggregate potential scores are derived from existing surficial geology mapping; higher scores are given to map units containing gravel with minimal silt and clay. Scores are lowered for units where overburden must be stripped to access the aggregate or where permafrost is present. Results are presented in a series of maps and a digital geodatabase.
