Construction of the Cal Sag Channel on April 20, 1917. The Sanitary District of Chicago (now MWRD) built the 16-mile long channel between 1911 and 1922.
Kevin Coyote-Trust Does MWRD know roughly where the pic was taken?
Joseph Obrien Looks like the Palos area with the moraine in the background.

Building the 1911-22 Cal Sag Channel
(Satellite, a comment suggested the Palos area with the moraine in the background. Unfortunately, I don't know where the moraine is. I do notice there is a Moraine Valley Community College.)
The Chicago Sanitary & Ship Canal that opened in 1900 reversed the flow of the Chicago River. This channel reversed the flow of the Calumet Rivers. The equipment to get material up and out of the channel has changed significantly since the CS&SC construction. Note the block of dolostone that the right "crane" is removing.
