Archaeologists have discovered artifacts in northern Minnesota that may date back as far as 14,000 years. The archaeologists found tools made of stone on a hill in Walker, Minnesota, while examining an area of the town that's slated for development.
About a half-dozen archaeologists and other scientists who have examined the artifacts say they are genuine. The archaeologists speculate the find will shed new light on early human activity in the state.
Colleen Wells with the Leech Lake Heritage Site program was part of the dig. She talked with MPR's Cathy Wurzer.
