INTERNATIONAL FALLS, MN—A place known for its frigid winter temperatures may soon be attracting visitors in the warmer months to see one of Minnesota’s most impressive ancient attractions. About 15 miles from the city, the site of Grand Mound, a 25-foot-high burial mound that is thought to be the largest prehistoric structure in the Upper Midwest, may once again be open to the public after remaining closed for 8 years, reports the Grand Forks Herald. Though once concerned about using a burial site as a tourist attraction, the Indian Advisory Council now believes that it would be appropriate to open Grand Mound to visitors once again and to continue efforts to ensure the mound’s long-term preservation. Grand Mound is the largest of five burial mounds that make up the site and were built by the Laurel Indians more than 2,000 years ago.
