Recently I have posted photos of the new Mill Race Path in Springfield. It is a 3.5 mile long trail that follows the old Mill Race dug late in the 19th Century to provide mills with water, etc. "The canal was hand excavated by Elias Briggs, the founder of Springfield. With his son Isaac’s help, he dug the canal in 1852, using an ox-plow and shovels in order to provide power for the first grist and saw mills in the area."

This is a scene of the beginning of the Mill Race Path at the downtown Booth-Kelly Trailhead at 307 S. 5th St.
