Digital compilation of surficial point and line features for Manitoba north of 54°

These datasets provide an up-to-date, interactive, digital compilation of historic and new point (ice-flow indicators, field sites, radiocarbon ages, outcrops, deltas, kettles, thermokarst) and line (streamlined landforms, eskers, Rogen moraine, moraines, meltwater channels, scarps, mass movements, dunes, crevasse ridges, beach ridges and trimlines and lacustrine/marine submergence limits) features that are typically present on surficial geology maps. This data can be used to better inform drift prospecting, land-use and research projects in Manitoba.


Click an NTS area on the image to the right to open the 1:250 000 map for that section.


Note: Portions of these datasets will be updated once a year as new field work is completed in those areas. In these instances, the file name of each map will reflect the year the material was last updated.
For example, the file named SG-GF2013_64N.pdf was released in 2013.


(Geology was digitized at scales between 1:250 000 and 1: 30 000, so the 1:250 000 PDFs in data-rich regions may be difficult to understand – we suggest the user refers to the digital data in these areas.)

Open File OF2013-10

Open File OF2013-10 outlines the methodology of this project and provides a description of each point and line feature. The datasets (attributed with source metadata), a moraine-polygon shapefile and a geodatabase of existing surficial maps in Manitoba are also provided.

Finding digital shapefiles for a particular area:

The datasets are available as a queryable layer in the Manitoba Geological Survey’s GIS Map Gallery. To find them, please do the following:

  1. Go to the GIS Map Gallery geoscience page and select "Geology of Manitoba".

  2. Once you agree to the Disclaimer and are in the GIS Map Gallery, on the Layers List panel, ensure that only "Geology of Manitoba" is selected. Click the arrow next to "Geology of Manitoba" and select only "Surficial Geology":

  3. Once the map adjust to the layers you have selected, proceed to zoom in on your area of choice to access the data.
    NOTE: You may have to zoom in quite a bit before your data will appear.

A note on data reliability:
This compilation is based predominantly on different types of remotely-sensed imagery, incorporating data presented at various scales. The data are considered more accurate where detailed (1:50 000 scale) surficial geology maps were produced, and where areas were updated using 1:40 000 scale aerial photography. Digital features such as striae, roches moutonnées, gravel pits, mines, radiocarbon ages, field sites, sample sites, and some outcrops, are mapped directly from field observations (spatial coordinates are expected to be accurate). The locations of all other features, however, are digitized from remotely-sensed products such as surficial maps (aerial photograph interpretation) or satellite imagery. As such, the spatial coordinates of these features are assumed to be reasonably accurate at their source scales, but misinterpretation is possible. Furthermore, the compilation does not attempt to encompass every single landform due to the limited resolution of the data, but is meant to provide a regional overview of glacial landforms in Manitoba. Aerial-photograph based mapping is required to provide further local-scale details
