Frozen deposits of interior Alaska

22 p. : ill., map ; 24 cm.Includes bibliographical references."A description of the frozen deposits in the vicinity of Fairbanks, Alaska, is given. The deposits consist of muck, sand, gravel, peat, volacanic ash and pure ice. The materials, other than the ash and ice, are shown to be of slope-wash and fluviatile origin. A large percentage of the ice is of glacial origin. The volcanic ash is the first to have been found in the region, and its probable source is discussed. The deposits contain large quantities of bones of Pleistocene vetebrates"--P. [1]
