The Umatilla National Forest Aerial Photographs consist of several (8) aerial photographs from the BTU project made by the U.S. Forest Service in May 1939 as well as a completed mosaic photo index (5 sheets) of the BTU project aerial photographs. The photographs depict forested areas as well as areas that may have been cultivated or used as rangeland. The photographs are annotated with section numbers and other codes that may indicate soil type. A few notations indicate crops under cultivation. These annotations may have been added by the Agricultural Adjustment Administration. Most of the photographs are of the area northeast of Ukiah near Owens Butte. The photographs are 21x25 inches, with a scale of 1 inch = 660 feet (1:7920); each photograph covers an area of approximately 2.3 miles by 3 miles.
