sited on a former marsh, chicago had PLENTIFUL clay for making bricks (at one time cook county had 60 active brickyards), but our clay had terrible color consistency, so the mottled bricks it produced (browns, yellows, oranges, salmons, etc.) were deemed inappropriate for front facades.
that's why it was used on the non-street facing facades of just about every single vintage masonry building in the city. face brick (or stone or terracotta) was then imported from other places with more color consistent clay that was used on the front facades of the city's masonry buildings.

Glazing that stuff would certainly make for an aesthetically interesting façade material. Just sayin'.

In the bulk of possible scenarios, St. Louis would be the American interior's dominant city. There's a reason why Cahokia's ruins are to be found in the St. Louis metro: the region was the greatest crossroads of trade routes to be found on the continent when trade would have been conducted primary or exclusively via navigation. It is in St. Louis where the main north-south trade route running up the Mississippi meets the main east-west one running down the Ohio and up the Missouri.
Had St. Louis had time to claim its primate role before the railroads came, it is unlikely Chicago would have surpassed it.
That said,
a major city was destined to grow up in the Chicago area, sitting, as it does, at the best portage between the Mississippi River and Great Lakes systems, and with the straight-shot trade route linking it with St. Louis that is the Illinois River, there are many many alternate history (and dystopian future!) scenarios you can imagine where the Illinois River valley becomes the heartland of significant empires stretching across the interior Midwest.
