The proposed Colville Mining District (CMD) encompasses 27,340 mi{sup 2} (70,800 km{sup 2}) in the central part of the North Slope. Known coal deposits within the proposed district range from Mississippian to Tertiary in age. Available information indicates that neither Mississippian and Tertiary coals in the CMD constitute a significant resource because they are excessively deep, thin, or high in ash content; however, considerable amount of low-sulfur Cretaceous coal is present. The paper briefly describes the geology and quality of these coal reserves. Difficult conditions will restrict mining of these coals in the near future.
