Historic site complicates work


Some 1,200 years ago, a group of American Indians cooked meals of beaver, deer or perhaps woodland bison on a stone hearth near the cool waters of a perpetual spring a few miles west of Springfield. The location had been a gathering spot for prehistoric people for thousands of years, based on items left behind. Stone spear points and arrowheads. Charcoal from cooking fires. Broken pieces of pottery and animal bones.
