Not a gunshot or center punch, looks to be random impacts from a tool such as a welders' slag hammer. Could some one have broken ice from the surface? Not a ball peen hammer, craterization to small.

Although very new to this activity, I have used my GPSr extensively in the past 8 years for various reasons. In benchmarking, the GPSr gets me close to the mark and from there I might as well shut it off unless I want it in the picture. The provided information, a good compass, distance judging, and imagining what the area looked like 60 or so years ago takes over from there. I also have a local advantage, being over 50 years old I remember things that are long gone.

My 2nd bm in 2 days. Granted, the winter here in SE NY has been timid compared to last year, there is still plenty of ice and the ground is frozen. I'll continue to hunt bm's but have learned to carry tools instead of relying on pointy sticks to dig with in frozen cover. Also learned that sunlit sheet ice makes a 4 wheeler swap ends if you let off the gas!
