Summary
The 1950s images were downloaded from Earth Explorer as medium-resolution scans of aerial photographs, with pixel size ranging from 1.33 to 2.32 m. Original photo scales were 1:54,000 or 1:20,000. (See Source Citation below.) I registered and rectified these images using identifiable common points from 1996 DOQQs. Images with filenames beginning "r37" were acquired 11-29-1953. Images with filenames beginning "r43" were acquired 01-31-1954. Image r1954r49_6786.tif was acquired 02-03-1954. Remaining images have the date of acquisition in the filename, starting with the format "ryymmdd...". Data derived from features mapped from the 1950s images were presented in: Friedman, J.M., Vincent, K.R., Griffin, E.R., Scott, M.L., Shafroth, P.B., [...]

This image set was used to map lower Rio Puerco arroyo geomorphic features (Highway 6 to Bernardo) in the mid-1950s. The mapped features were used to compute average channel and arroyo widths and to determine shrub canopy cover across the arroyo bottom in selected segments. Results from mapping were used to determine geomorphic change in the arroyo through time since the 1950s.
