Sand and Gravel Resources of the Athabasca Area, Alberta

A reconnaissance sand and gravel study was conducted in the Athabasca region. A literature review and airphoto interpretation identified 639 areas with potential for sand and gravel. As many sites as possible were then described on the ground. Access to sites was gained through a combination of truck, ATV, helicopter and jet boat. After fieldwork 100 areas retained potential. Eighty-seven of these were ground checked. The types of deposits with the greatest potential for gravel are Athabasca Valley terraces, preglacial deposits on the Pelican Mountains, outwash and alluvial deposits derived from these preglacial deposits, and thrust deposits in the area of the AIPac mill site. Gravel is in short supply in many areas but there is potential for the discovery of new deposits.
