The Green Bay Trail ran near the shoreline of Lake Michigan and crossed the Chicago River on the sand bar of its original mouth. The trail also had an intercepting trail that branched out from the main trail near Gross Point and followed the contours of Old Calumet Beach through Niles Center, Jefferson Park, Cragin., Austin, South Oak Park, Berwyn, and Riverside, In Riverside the trail again divided at the intersections of Forest Avenue, East Avenue, Burlington Street, and North Longcommon Road. The westerly trail or Barry Point,. proceeded southwest down East Avenue and crossed the Burlington Railroad tracks at East Avenue and Pine Street reaching the intersections of Blooming Bank and Barry Point Road. Proceeding south down Barry Point Road, the trail reached the intersections of Barry Point and Fairbanks Road to turn southeasterly down Fairbanks. The trail then crossed Riverside Ford, located 150 yards north of the Hoffman Bridge on which present day Barry Point Road enters Lyons.
Most evidence of Riverside Ford has been obliterated by the building. of the Hoffman Dam and a small dam North of the Hoffman Bridge constructed with the purpose of leveling the height of water in the Des Plaines River. A historical marker was placed on the east side off of Fairbank Road at Riverside in 1932 by the Woman's Reading Club of Riverside with the aid and assistance of the Chicago Historical Society. It reads ---

One locating the true ford will find it almost directly south of the small dam north of the Hoffman Bridge. On the east bank of the river there exists a type of grove in the slope leading down-into the river which can bear out proof of a trail once existing there and the slope being worn down from the pioneers and Indians draggin their weary bodies and belongings down the slope to the rocky ford below. On the westerly bank of the river there still exists a small part of the Barry Point Trail where it travels southward through the forest preserve until reaching the intersections of Barry Point Road and Joliet Avenue in Lyons.
To find the final - Read the plaque and find the date it was dedicated.
To find the north coordinate of the final Add the four numbers of the date together. Divide by 3 and add that number to the decimal portion of the posted north coordinate.
To find the west coordinate of the final Multiply the four numbers of the date together. Add 30 and subtract that number from the decimal portion of the posted west coordinate.
