Bedrock geology index map
The Bedrock Index provides a spatial record of the location of all Bedrock maps published by the Geological Survey of Canada and hosted on Geoscan. The index has three "series" of maps; CGM, A series, and preliminary maps. In cases where there have been multiple editions of a map, the most recent record is reported in the Bedrock Index attribute table. Maps published in Open File documents are not recorded in the bedrock index.
The "A" series maps were produced from 1909 to 2010 and have been replaced by the CGM (Canadian Geoscience Maps) series. CGM maps began production in 2010 and are still being published. Preliminary maps were published from 1941 to 2021.
