Summary[edit]
DescriptionThornton Quarry (27407239659).jpg |
Thornton Quarry, a large rock quarry south of Chicago, as seen from an airplane flying into Midway (for a layover, like the rest of my Chicago photos to date). The north lobe of the quarry, somewhat visible in the middle of this photo, is now a dirty-water reservoir for the Chicago drainage system. A dam was built in the tunnel under interstate 80 to prevent the water from entering the still-active south lobe of the quarry. At the time of its construction, the water reservoir was believed to be largest reservoir of its kind in the world. This image is licensed with a Creative Commons Attribution license. I did this for this image (not all of my images have this license, most are all rights reserved), as I feel that it is an interesting image of a somewhat underappreciated engineering marvel. I had trouble finding information on this subject when I was researching this photo (which totally stunned me when I saw it from the plane), and I hope that my photo will help there be more information out there about this subject. This license means that you are free to use this image in whatever way you want, so long as you give me credit ("Attribution"). |
