Digital General Land Office Maps
Also known as Donation Land Claim maps, these maps show the original settlement and ownership patterns in Oregon. These are large JPEG images in .zip files (1-2.5MB). All files are geospatially organized by quadrants as shown below. If you do not have the Flash player, there are plain-text links directly to the individual indexes at the bottom of this page.
