Sediments mined from the sand and gravel quarry are from erosional deposits consisting of a heterogeneous mixture of materials. The deposits are related to the advance and retreat of continental glaciers that moved back and forth between Canada and Illinois. The glacier deposited materials by its meltwater. Consequently, the quarry has well sorted and layered deposits. Size distribution of sediments concerns the amount of each different size fraction in the deposit.
Material can range from clay sized particles to boulder sized particles.
Glacial gravels, in general tend, to contain coarse sediments. Sediments deposited above the water table are usually brownish or reddish in color. This is due to the oxidation of ironstone particles in the deposits. Once the limestone is removed from the earth, it is feed through various machines in order to get it ready for customer use. The Hammermill crusher is a machine that the quarry often employs.
