This report describes one phase of an investigation conducted for the Airport Development Division, Technical Development, of the Civil Aeronautics Administration, by the Joint Highway Research Project, Engineering Experiment Station, Purdue University. It supplements an earlier publication The Origin, Distribution, and Airphoto Identification of United States Soils., Civil Aeronautics Administration Technical Development Report No. 52, May 1946. Even before Technical Development Report No. 52 was published, it became apparent that supplemental work would be desirable in order that information concerning airphoto analysis of soils of the Western United States be brought up to a standard comparable with that developed for the Eastern States. This report, dealing with the supplemental work performed, describes the following airphoto patterns Glacial materials of North Dakota and Montana aeolian soils primarily of the Columbia Plateau sandstone and shale materials of Montana and Wyoming igneous materials from many States in the Northwest, including considerable information on the basalts of the Columbia Plateau Great Plains outwash materials and soils of filled valleys including the Willamette and the Great Valley of California, plus some Basin and Range data.
