Existing surficial geology maps of Manitoba at scales ranging from 1:50 000 to 1:500 000. These maps are published mainly by the Geological Survey of Canada, although some are co-published with the Manitoba Geological Survey. The 1:50 000 scale maps are a mixture of detailed, resource-based and/or preliminary mapping. Surficial geology map-index polygons are available in the accompanying zip file; from these, users can quickly generate a list of all available maps and scales for specific areas.

These Manitoba datasets provide an up-to-date digital compilation of historical and new point (ice-flow indicators, field sites, radiocarbon ages, outcrops, deltas, kettles,
thermokarst) and line (streamlined landforms, eskers, Rogen moraines, moraines, meltwater channels, mass movements, dunes, crevasse ridges, b...

... point and line features from pre-existing surficial geology maps in Manitoba (Figure 1) were digitized (along with corresponding metadata) and edge-matched at the most detailed scales available. Line features were digitized to scale, whereas points represent features occurring at a site but are not to scale. ...

The GEM program has facilitated the availability of new and converted surficial geology maps and associated digital datasets for large sectors of northern Canada, leading to about 70% of the north being mapped and digitally available. Development of the Surficial Data Model (SDM) and Canadian Geoscience Map (CGM) series have streamlined the publica...

... The starting point for updating the marine limits were the previously mapped linear features from GSC Open File 8717 in central mainland Nunavut (Behnia et al., 2020) and data within MGS GeoFile 1-2022 in Manitoba (Gauthier, 2022a). Other sources of information included marine deltas, shorelines and sediments compiled from published maps (various GSC maps in Nunavut -references in McMartin et al., 2021;in Manitoba -references in Dredge et al., 2007 andGauthier, 2016), and field elevation measurements of the marine limit (same references as previous). ...
The Geological Survey of Canada and the Manitoba Geological Survey created a compilation of mapped marine limit indicators from the time of marine incursion during the last deglaciation in central mainland Nunavut and northern Manitoba. These indicators were used to interpolate a maximum limit of marine submergence at any one time between Churchill and Queen Maud Gulf. The report provides a summary of the data sources, cartographic methods, and geomorphological implications, and releases the compiled mapped limits, as well as the interpolated limits at full resolution and in a generalized version. The full datasets are available for downloading from https://doi.org/10.4095/330940
This project involves the compilation of all available Quaternary stratigraphic and depth to
bedrock data for northeastern Manitoba. Modelling of the drift thickness using point data provides the first regional-scale overview of drift thickness of the region. Increased accessibility to Quaternary stratigraphic and depth to bedrock data will increase the effectiveness of drift prospecting approaches in this remote and thick drift covered region of Manitoba.
