Peace River Lowlands Subregion

Peace River regionThe Peace River Lowlands Subregion consists primarily of fluvial landforms along the lower Peace, Birch and Athabasca rivers including the Peace-Athabasca Delta, one of the largest freshwater deltas in the world. Although the bedrock is seldom exposed, it influences the character of till deposits and groundwater discharge. The bedrock includes Cretaceous marine shales and silty shales, Devonian marine limestones and dolomites, evaporite gypsum and anhydrite, and marine shales and siltstones. Some lacustrine deposits also occur in the Subregion.
