In 1929, John D. McAdams, business manager of the
Alton Telegraph, made the suggestion to create a monument commemorating
Jacques Marquette as the first European to land in Illinois. This
suggestion was made to H. H. Ferguson, a local landowner, who had the
monument designed. The monument was erected where Ferguson believed the
mouth of the Illinois River was likely to have been located at the time of
Cut from a solid piece of dolomite, the monument is
seven feet six inches high. It is situated on a ledge of a bluff that
overlooks the Illinois River. Two flights of dolomite stairs lead from the
Sam Vadalabene Bike Trail up to the cross. The monument is located 4 1/2
miles east of the main Park entrance on the Great River Road (Route 100.)
