This is shot of I-294 south of Chicago. The pit is the Thornton Quarry. The sky is the sky. I had to make sure some of the cars and trucks stood out, so insignificant were they. Same with the roadbed.

Very interesting image Bob. Its one of those that the more you study it the more you see. It appears the quarry is on both sides of the nearer lanes of traffic with that bridge over part of it.

You are right, Dave.
Here are two more interesting facts about the quarry:
It is the same geologic layer as Niagara Falls. A few eons ago, something slammed into Michigan, uplifting that layer, now at the surface near Chicago and in upstate NY.
Half of the quarry is now sealed off, to be used as an overflow reservoir for the Deep Tunnel Project, which is designed to stop flooding in Chicago. Having reversed the flow of the Chicago River, the city does not drain into Lake Michigan--a heavy rain causes flooding.

Still growing it seems. Wasn’t that known as or operated by Marblehead in the ‘70s-80s’ or am I thinking of another?

Not sure of its previous names. But yes, still being worked.
