Map of Fort Clark, Hatteras Inlet from National Archives

On a recent research trip to the National Archives, I stumbled on this undated Union map of Fort Clark, part of the defenses at Hatteras Inlet. Though not relevant to my research, it seemed like a interesting sketch. Judging from the units mentioned on the map, I assume it was drawn in fall of 1861. I have not seen this reproduced elsewhere - though my knowledge is by no means extensive. If anyone has additional information, feel free to email me. Source: RG 393, Dept. of Va. and N.C., Misc.
