Asticou, 1 mi. N. of, 150 N. of bridge over outlet to upper Hadlock Pond, in ledge 50 ft. W. of center line of rd.; standard disk stamped "K-18-1934" "P.B.M. 231.2" on ledge, telephone pole and concrete weir.
This USGS mark was an accidental find (sometimes they're the most enjoyable!). Somehow disoriented after hiking Norumbega Mountain, we took a wrong turn at a wooden bridge over a creek and ended up not on the trail back to the parking area, but directly on Route 198 a half-mile south of our goal. We decided to trudge back up the road rather than enter the woods again in search of the trail. And on our way, directly across the road from the outlet of Upper Hadlock Pond, I happened to look off to my left and spotted a witness post! The mark was well exposed and easy to see from a distance. This is one of several marks in the USGS "K" series level line that were not incorporated into the NGS database.
