Master Map Gets an UpdatePosted September 26, 2012The archaeological excavation of Fort Michilimackinac has been ongoing for more than five decades and detailed notes and records of each season, each site, and each square are important to our understanding and ongoing research. That accumulated data is presented in one, large document, the master map, which shows all of the major features excavated within the palisade wall from1959 until 2007, when the most recent project was completed.Much like the time spent in the field excavating artifacts, maintaining those documents can be a time consuming, but fascinating endeavor.Georgia Wulff updates the Colonial Michilimackinac master map with information from recently completed archaeological excavations at the site.“The master map shows how all of the features, most of which are structural features such as parts of buildings, relate to each other, tying all of our projects together,” said Dr. Lynn Evans, curator of archaeology for Mackinac State Historic Parks. “This is important because we are interested in understanding the community, not individual structures isolated in space.”Georgia Wulff, an artist from Minocqua, Wisc., met Dr. Evans on a study tour and offered to help update the map. But, this wasn’t Wulff’s first trip to northern Michigan, far from it.“My family took a number of trips to the Upper Peninsula when I was younger,” said Wulff, noting that her grandfather served as lighthouse keeper in Manistique and her great-grand father served as lighthouse keeper in Traverse City. “I even remember coming across on a ferry before the bridge was built.”“The master map is also important for planning because it shows where we have and where we have not excavated. We don’t want to install fences or underground utilities in undisturbed deposit,” said Dr. Evans.She added that, ideally the map would be updated at the end of each major project, when the important features are better understood. Things such as rodent runs and modern disturbances aren’t generally included on the master map for the sake of clarity.
