While investigating archaeological and historical sites in and around Ste. Marie among the Huron and the Martyrs Shrine I reviewed "Before and Beyond Sainte Marie" (Friends of Sainte Marie - 1995) and was able to use the research contained within this publication to support the identity and location of numerous sites of interest close to the land in question.
While reviewing this report I came across a section that I had highlighted in earlier research regarding the water level of the Wye River at the time of Ste. Marie (top of page 201). This led me to another report commissioned by the Wye Marsh (Ste. Marie's neighbour on the Wye) regarding the origins of the marsh and the water levels over time. http://www.wyemarsh.com/conservation/pdf/Chittenden-1990-OriginoftheWyeMarsh.pdf
Why water levels matter?
Why should we as historians or archaeologists care about water levels? In the above noted report it concludes that the water level of the Wye River at Ste. Marie was 11 ft. higher than it is now (publication date 1990) and hence all of Lake Huron had a higher water level at the time of first contact.
When looking for landing sites that relate to Champlain, Sagard or the Jesuits or the ports used for trade or the villages that supported these ports and landing spots 11 ft in additional depth of water on an area of now shallow beach with a gradual slope inland can make a significant difference as to where one might look for such a site.
I want to suggest that we need to study this subject further as it is obvious from some of the earliest posts on this blog that some influential thinkers in the historical and archaeological community maintain that the water levels of Old Huronia are essentially the same as they are today.http://www.oashuroniachapter.com/2006/05/canals-and-water-level.html - http://www.oashuroniachapter.com/2006/06/more-on-water-levels.html
Should you have additional documentation in support of either theory please post or make a comment and perhaps we can add the subject to our list of possible presentations for the upcoming year.
