Geology and cement raw materials of the Windy Creek area, Alaska

January 1, 1953

The Windy Creek area, on the south flank of the Alaska Range in the Alaska Railroad belt, contains deposits of raw materials which could be utilized in the manufacture of portland cement.

Bedrock in this region includes limestone, argillaceous rocks, chert, and a wide variety of other lithologic types ranging in age from Devonian to Cretaceous.

The major geologic structures of the area are oriented parallel to the regional northeast trend of the Alaska Range. Devonian rocks crop out on the south flank of the range, with generally north-dipping strata of Mesozoic age occurring in the area to the southeast. A northeast-trending fault separates the rocks of the two eras.

Two limestone deposits of the Devonian system are of adequate size and quality for cement manufacturing purposes. They are located 7 and 11 miles west of the Alaska Railroad; argillaceous rocks occur in both the Devonian and Jurassic(?) systems and are found in many parts of the area. Chert, of Triassic age, possibly of some value as a high-silica component, was found adjacent to the Alaska Railroad near Windy Station.
