The land near Lake Minnetonka is home to many Indian burial sites. So, when 5000 yards of soil were removed for Tonka Bay infrastructure projects designated as burial grounds, the reaction was immediate.   Under the supervision of the Minnesota Indian Affairs Council (MIAC), tons of soil are now temporarily stored near Manitou Park and Tonka Bay City Hall.   A permanent relocation site proposed by MIAC and the city is meeting resident resistance.
