An aerial view, taken in the 1930s, of the old Wolf Lake Speedway right in the middle of Wolf Lake.

Today, a small island parcel sits in the middle of Wolf Lake near 123rd  Street and Calumet Ave.  In the 1930s, this parcel was actually part of the lake front with the old one-mile track sitting west of it and the fifth-mile midget track being situated slightly to the southeast near the current boat dock at about 124th St.
