Selective cementation of the coarsest sediments in exposed stratigraphic sequences of the Cypress Hills Formation and the Wood Mountain Formation in Saskatchewan is a post-depositional feature of recent origin. It is governed by locally prevailing hydrologic conditions and by the factors that control the precipitation of calcium carbonate in the interstices of sand and gravel at the air-rock interface. The lateral extent of cementation is small and the process is continuous with slope retreat.
