This investigation of soils and permafrost (frozen ground) in Alaska was undertaken in order to evaluate conditions for construction in cold climates, of buildings and airfields, using aerial photographs for terrain analysis. Includes data on geology, geomorphology and climate, with numerous examples of aerial photographs and instructions for interpretation.

Water-deposited materials in Alaska are important for engineering uses because of their general flat topographic situation and abundance. For the purposes of this study, the airphoto patterns of water deposited materials are divided on the basis of origin as follows: coastal plain; stream-deposited materials in the form of flood plains and terraces; and deltas. There are several other water-deposited types such as lacustrine, valley fill, and the several outwash groups. Outwash materials are discussed in the chapter on glacial patterns since complete knowledge of the pattern and its suggested features frequently depend on an analysis of glacial events. Successful interpretation of conditions of various water-deposited materials is contingent on the treatment of each topographic situation as an entire and separate unit. (Author).

The report, entitled 'Evaluation of Soils and Permafrost Conditions in The Territory of Alaska by Means of Aerial Photographs, ' presents the results of one phase of the investigation of airfield construction in arctic and subarctic regions being conducted by the St. Paul District, Corps of Engineers, Department of the Army. The overall investigation has as its objective the determination of design criteria and construction methods for areas of permanently frozen ground. The objective of this phase of the investigation has been the development of a technique whereby engineering soils and permafrost conditions could be evaluated from aerial photographs. (Author).
