Oregon Historical County Records Guide
Polk County Records Inventory
Series provides visual documentation of changes made to county lands through development and by natural and man-made disasters. The photographs are taken at intervals along a series of flight paths to attain coverage of all or part of a county. They generally include flight path or township, range, and section numbers; show natural and man-made features; and are produced in black and white or color prints to varying scales. An index by quadrant may also be included.
The University of Oregon, Map & Aerial Photography Library Aerial Photograph Collection includes aerial photographs from most Oregon counties.
