This page is under construction (March 2019). When it is complete, it will include links to the full bandscans of a few dozen sites along the beaches of the Great Lakes and Atlantic Ocean.
For now, the following locations have been completed:
Lake Superior Bandscans (18 bandscans)
Lake Erie Bandscans (4 bandscans)
Lake Ontario Bandscans (6 bandscans)
Lake Michigan, Lake Huron, and the Atlantic should be added by mid-spring. While the scans are long done, organizing and typing up the information takes a lot of time.
