Oregon Historical County Records Guide
Gilliam 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.
Aerial photographs dating from 1998 to 2005 (color) are maintained digitally on a computer in the appraiser's office.
