Straight off the bow in that pic is the I-90 bridge. Just a sidenote, under the bridge is an island. On the island there was a large wooden roller coaster from about 1910 to about 1919 when the riverside park there had many amusement rides and games of chance. Under and just north of the bridge was where folks would rent a canoe or rowboat and picnic in the water. Prior to that era it was the spot of large outdoor gatherings, where folks from the city would come by the hundreds for a weekender by the river in the summer time and locals would have skating parties in the winter.
Upstream is the site of the countrfeiters who were discovered by a Dundee barrel maker named Pinkerton. He got some locals including the constable and blew the place up with black powder, then went on to create the agency named after him and Abe Lincoln's special security force, later known as the Secret Service. Didn't work out too well for Lincoln, eh?
Most of this shoreline is now Kane County FP and off limits to detecting. But you can find an occasional barrel hoop in the water, or so we hear from time to time...
