Recovered in good condition as described in the NGS datasheet with the exception that Grass Lake railroad station no longer exists. This BM is also listed on a topography map as 'BM Herd Azimuth 4854'. The Herd Azimuth Mark is part of the HERD BM series on top of Herd Peak: (visit link)

My more accurate coordinates should place you very close to this station.
