MINNETONKA — Work continues to restore Indian burial mounds in Minnetonka mistakenly disturbed during road construction.

Before work on county Road 101 began last fall, the land was surveyed and the burial ground was thought to be 30 to 50 feet east of the site. But when the project was started and bone fragments were unearthed, the construction work came to a halt.

Now, the Minnesota Indian Affairs Council and Hamline University archaeology and anthropology graduates are working to restore the mounds. The Star Tribune reports crews are meticulously sifting through dirt to recover remains or artifacts. The restoration work is expected to take four more weeks.
