Talk:Thornton Quarry

Untitled
I couldn't find good info on the "largest stone quarries", but from things I ran across, it sounds this is often refered to as the second or third largest quarry in the world, but these may be bigger: --Interiot 20:01, 25 December 2005 (UTC) yoyos —Preceding unsigned comment added by 71.201.136.101 (talk) 21:34, 10 January 2008 (UTC)

Type of rock
If anyone knows, it would be nice to say what kind of rock is quarried at this site. I'm guessing limestone, but we don't guess on Wikipedia! Jnmwiki (talk) 03:25, 15 July 2016 (UTC)

Contract with MWRD
I started a section on the use of the Thornton Quarry to hold stormwater prior to treatment, under contract with Metropolitan Water Reclamation District of Greater Chicago since 1998. I took info from other Wikipedia articles but used no other sources. I suppose some of those are needed. - - Prairieplant (talk) 15:39, 4 June 2019 (UTC)
