IMHO we do have camps inside blue circle , lower red bordered shape is ours, the other red inside blue and all other red is chinese camps.
You are right , i cant see any foot trails for our camp either , could be because we move along the ridge line.
That nathan osint guy on twitter posted hires sat images of that area , he said its chinese camp , but looked clearly indian to me.
i think @detresfa_ also marked it as indian.
big shame that we couldnt get control of helmet top , like you said i think it was because of casualty.
