I scanned this old map to share because it shows farmer's fields which some other maps do not. I dug this out because my post referring to Recreation Field got two comments about what the name of the field was historically. I did remember it being called Glenn Field but was not sure where the dividing line was. Someone else commented that the area that the North Carolina monument is at is Brock Field (a second Brock Field). This I did not remember but the map proves this to be correct too. This area is on the first map section, above the word Park in the title, Chickamauga Park Base Historical Map.
This map is one of those treasures I found at TIC that I've talked about previously. The first three pictures are sections of the map and the final picture is the entire map stitched together.
