The Wood Buffalo National Park is underlain by Devonian period sedimentary bedrock (gypsum, halites, dolomite and limestone) and covered by glacial deposits of varying thicknesses. The uniform relief, porosity and solubility of the bedrock have produced a drainage type that is primarily vertical and percolating rather than horizontal across the surface of the land. Water percolating through the soil and bedrock causes saturation of the plains surface. This has created karst landforms in areas of gypsum bedrock. Other phenomena include salt flats, underground streams, sinkholes and saline streams. The boreal plains are a mosaic of muskeg, meandering streams, shallow lakes, bogs, and boreal forest. I hope this helps you. Regards, Warren
