Crestmore QuarryEdit

The former and large Crestmore Quarry is on the east side of the hill.[3] The Riverside Portland Cement Company had its plant here, and used both the limestone and the underlying granodiorite for its manufacture of cement. Mineral specimens were also collected from the mine.[4]

As of March 2015, the mining operation of the former TXI cement manufacturing facility has stopped. As the shut down of the operations of this historic facility progressed, the quality of the environment appeared to have increased.
