West Mifflin, PA: Slag Dump

(Satellite, between PA-51, Lebanon Church Road and Clariton Road. It is the home of a lot of "big boxes" today. See the topo maps at the bottom of these notes.)

US Steel had blast furnaces along the shores of a lot of the Monongahela River. The slag from three of those mills was dumped here. The railroad was Union Railroad, which I think was a US Steel railroad.

Butchie Honsaker: You know years ago there were 17 Blast Fces. in the Mon Valley. Just 2 left at the Edgar Thomson where I worked for 35 years.

: After my high school prom in 1947 we went to watch the slag be dumped. It was a high school dating location!
Nick Shelton: That would be cool to see at night

Scot Bierman: Not the only slag dump in the area. Directly across from the Homestead Works at the foot of the High Level Bridge, now renamed the Homestead Gray's Bridge is a slag dump off of Browns Hill Road. It is now a housing development called Summerset. The homes have no basements like a typical Pittsburgh house will. Because you can't get through the slag except at extreme expense. I grew up about a half mile from the back side of this dump. Slag was hauled there and to West Mifflin constantly.
