The Civil War in NE North Carolina
The photo doesn't specifically say this was taken on the Hunchback, but things look similar to other Hunchback photos I have seen.
Notice the details in the supports and the facing around the edge of the roof.
Below is a section of an identified photo of the Hunchback. Note that the officer on the right in both photos appears to be the same man.
In the photo below, the same officer appears again, this time on the left. Both of these photos are identified as being taken on the Hunchback. I'm not sure if the other officer in these two photos is the middle one in the top photo in question because of the poor quality, but the hat and uniform look the same.
