Rod Johnson, President of the Minnesota Archaeological Society will be demonstrating how stone tools like arrowheads are made at the Welch Station access of the Cannon Valley Trail on Saturday September 4, 2010. Rod will be set up at the Welch station from 11 am to 4 pm. The trail runs from Cannon Falls to Red Wing and is an enjoyable days outing. At a couple of locations along the trail near Red Wing there are interpretive signs explaining archaeological sites adjacent to the trail. The Cannon Valley Trail web site also has a page about the cultural resources found in the area.
