in the early 20's to the 50's that used to be the mining pit for the carry brick co. they exavated the mud to make the paver and house bricks for the streets of chicago. the baking ovens stood right behind the brick yard mall to the west. com ed uses the property now. the baking ovens used to run north and south from deversy to grand. what really happened from what i told by my dad they hit a under ground spring while digging in the late 50's and it began to fill with water. he lived right next door to the wolf camera shop on deversy just one block west of narragansett when he was a kid. i remember looking through the fence when i was just a kid visting my grand parents who stll lived there up untill the early 70's. seeing the trucks and real steam shovels that dug and brought up the brick mud. they looked like small toys on the winding road around the pit. it was really deep! carry brick went bust after that. it became a land fill in the 60's for the city when it was topped off, someone got the idea to build a ski resort on top of it. it only lasted for a couple of winter seasons and closed. the land sat dorment for years for the exception of some car dealer parking new car inventories. untill they built the mall. that was a weird area around there. they had a road a few blocks away in back of a goverment factory that went no where. they say it was to test radar during ww2. that's another story!
