Beaver River sandstone is a rock type locally found in northern Alberta, Canada that was extensively used by First Nations people in pre-historic times. Rediscovered during archaeological excavations carried-out in the Oil Sands region of Alberta, Beaver River Sandstone appears as a significant lithic resource during the early pre-historic period. The material type has been redefined by geologists enamored by its enigmatic character, which include Muskeg Valley Silicified Limestone (MVSL) and Muskeg Valley Micro-quartzite (MVMq).
