ENDEAVOR, Wis. (AP) -- Surveyors suspect there are ancient Native American burial mounds in the Marquette County village of Endeavor.
Village leaders considered several development proposals for the site, but federal law requires local tribes to first survey the area.
Ho Chunk surveyors used ground-penetrating radar and found outlines of four mounds so far.
Wisconsin law prohibits the disturbance of mounds and other human burial sites.
Tribal archaeologist Jay Toth says many of the site's mounds were destroyed by the early operators of a school that was run on the land in the early 1900s.
Toth says they may have used the remains for science projects.
Village President Kevin Boodry says board members and tribal officials will figure out the next step.
