This GIS dataset portrays an interpretation of bedrock erosional domains of the Grande Prairie–Valleyview area. The erosional domains are the product of cyclic fluvial incision and lateral planation that has resulted in a step-form bedrock topography. Four planation surfaces are correlated across the study area including incised valleys (no. 4 surface), low benches (no. 3 surface), intermediate benches (no. 2 surface), and upper benches and rugged eroded uplands (no. 1 surface).
