The Peggy Helmerich Library will be closed temporarily for light renovation. We anticipate the closure to last several weeks. During the closure, any items you have placed on hold will be sent to Hardesty Library.
We've added a collection of 1950s and 1960s USGS aerial maps of Tulsa County to our Maps digital collection. The maps provide information about Tulsa's changing landscape. For instance, the Blair mansion property (changing to A Gathering Place soon), Arkansas River pedestrian bridge, and 31st Street are pictured left (click here for a larger image) minus parking lots.
The ability to zoom in with any clarity and the time it takes to load a larger file is a balancing act. With the aerial maps, we chose clarity over load time. As a result, the images are largish and may not automatically load depending on the browser/device. You may need to click on “download” to retrieve the image, and it may take a bit to load.
We didn’t have a clever way to name 174 aerial maps in a distinct manner so they all have the same title, but you will find that the descriptions list the Townships, Ranges, and sections covered by each map. The search page is configured in a grid view, so unless you change the default view, the description will be shown on the browse/search page.
Because the maps are described using Township/Range/section, you might want to search by Township and Range and then browse the descriptions for the appropriate section (For example, search using "19N" and "12E." The Tulsa County Assessor provides online access to Tulsa County maps that will assist with area identification: http://www.assessor.tulsacounty.org/assessor-maps-county.php.
Finally, the maps have been rotated to face north (if we missed a rotation, please let us know), but this rotation means that a photograph's edge markings may appear upside down or sideways.
