The area to the south and east was once part of the Shumaker Naval Ammunition Depot. Note the oddly lettered highway running east from US 79. The highway in question is part of today's AR 205. I'm guessing "NR" stood for "Naval Reserve" or something similar. But what did "DA" stand for? How was this highway signed, if at all? And was there a DA NR-2? What's the story behind this oddity?
Special thanks to Geostor for the historic map images.
