Individual prints are organized by exposure number and grouped by navigational pools. The flight path follows the Mississippi River (downstream and upstream). The photos will all be displayed with the exposure number in the lower right corner. This does not mean that north is always at the top of the digital image. Since the flight path follows the path of the river each individual photo will need to be rotated to match the area of the river they are representing. Some photos may need to be rotated up to 180 degrees.

Links for each scanned print are displayed by exposure number. Prints that were missing from the collection are listed but do not have a link associated with them.

An index to the prints is available via this document.
