    Seeking the meaning of reference "GSM"

    Tracy Harding Newbie

      I am trying to figure out what "GSM" means in the reference below; it is from a book on place names in Michigan, and "GSM" plus a year appears in several places.  In particular, I'm trying to find more specifics on what it was that Vine Harding did to "develop" his resort officially in 1906.


      WAWATAM BEACH , Cheboygan County : it was the site of Fort Michilimackinac ... it was developed as a resort by Vine Harding in 1906 [ GSM 1907 ]
