Downhole geophysical data from boreholes along the Spiritwood buried valley aquifer near Cartwright, Killarney, and southeast of Brandon, Manitoba

Contents: Open File 7080 documents work completed by the Geological Survey of Canada in support of Natural Resources Canada's 'Groundwater Geoscience Program', as part of the aquifer assessments and mapping of 30 key Canadian aquifers. Buried Valleys are one thematic aquifer type that are
common across Canada and are of particular importance in the Prairie Provinces. The Spiritwood buried valley aquifer study in south-western Manitoba is investigating an area of approximately 1000 km2 extending northward from the USA - Manitoba border.
This Open File contains the results of the downhole geophysical logging conducted in nine boreholes along the inferred lengths of the Spiritwood and Yellowstone-Missouri buried valleys. The boreholes were independently drilled by Manitoba Water Stewardship (MWS), the Town of Killarney, and the GSC.
The objective of the surveys was to measure a range of chemical and physical properties of the subsurface materials, and compare these results to those of the surface and airborne geophysical surveys previously carried out in the region by the GSC.
