| Abstract | Understanding of the Medora-Waskada buried valley aquifer in southwestern Manitoba is reviewed. New seismic reflection surveys delineate the valley along four transects and provide insight into the
nature and distribution of the valley fill. Survey results suggest that the valley may have been eroded subglacially as a tunnel channel. The seismic cross-sections show that: 1) valley walls are steep, 2) sedimentary sequences are complex, and 3)
seismic facies vary within the valley suggesting sediment bodies of different grain size and permeability. |
