Abstract
The North Battleford fluting field is located on the western edge of the Saskatchewan Plains in a large embayment in the Missouri Coteau. The distinct ridges and grooves of the fluting field begin at the upflow facing rim of the North Saskatchewan River valley and continue in a narrow zone 50 km toward the southeast, transverse to the direction of regional ice flow. Based on sedimentological and geomorphological observations, it is interpreted that the North Battleford fluting field has an erosional origin, and that the erosive agent was the large-scale, turbulent flow of subglacial meltwater. The regional-scale flood event also eroded a broad, almost featureless plain adjacent to the fluting field and discontinuous channels and hummocks at the northern wall of the embayment in the Missouri Coteau. Lobate gravel deposits and associated zones of intense scouring in central Saskatchewan were also produced by a subglacial sheet flow of meltwater. The smaller scale event occurred during the final deglaciation of the area as subglacial meltwater issued from the margin of the retreating ice sheet. Sheet flows of subglacial meltwater were a recurring and significant geomorphic agent in the evolution of the prairie landscape.
