Anthony, if I had to guess, I'd say it is all part of Miacomet. If you add the 7 holes you are talking about to the holes NE of the road, you get 18. Plus the crazy bunker style you noted is also used on the 2 holes farthest to the NE. It looks to me like there are remnants of abandoned holes on the main part of the property. I'll bet this was a shortish course that was redone at some point to add length.
