While digging around on some aerial photographic archives I found an image from 1938 showing Chicago’s now defunct Riverview Amusement Park (1904-1967). You can see some of the amusement park rides (the Chutes and the Bobs) and other features. That’s the north branch of the Chicago River on the top of the image. I also pulled an old map off Pinterest showing site attractions.
