There are actually three USGS Benchmark disks for the highest point(s) in Delaware, also known as Ebright Azimuth.

The most famous and seen USGS Benchmark disk is adjacent to a sidewalk.

Another USGS Benchmark disk is in a private trailer park residence, rarely seen.

And, finally, the USGS Benchmark disk seen in this photo is located up an adjacent road only a few blocks' distance from the "official" (sidewalk) disk.

Photo taken on August 3, 2008.
