Crucible mine, or: How did your slate dump get on our side of the river?

Well it's not the only time it's happened.  La Belle's staggering slate dump was actually the waste from J&L Steel's Vesta #4 and #5 mines.  In La Belle's case, however, the entire prep plant was on the Fayette County side of the river.  A conveyor belt across the Monongahela river carried the green coal to the plant, which was built around 1950 and I'm told at the time was the largest such prep plant in the world.  Another conveyor led from the plant to the behemoth of a dump.

Crucible was also a captive mine (of the Crucible Steel Company) however they never had a prep plant on this side, just the dump.  And they didn't have a conveyor belt to bring it over, they had a skip, or as they call it on a mine map an "Aerial Tramway", basically like a ski lift but for buckets of mine waste.  The mine opened in the early 1910s but they must have dumped on their own side for awhile.

It wasn't there in 1939.

It was in 1959.  Probably nearing the end of the mine's life, it shut down by the early 1960s.

So what's left today?  Well I haven't been to the other side but the dump is still there.

 While not the biggest slate dump around in area, these "twin peaks" sure are tall!  Also note the bottom has largely turned to "red dog", a byproduct once used to cover rural roads, today that's the job of gravel.  There aren't many "red dog" roads left, probably due to environmental concerns.

No idea how the overhead skip worked but this must be what's left of it, there's no other reason cables like this would be just hanging out on the top of this pile.  Presumably they had bulldozers or something on this side to even the pile out from time to time.

Update: Sarah's coal

Well it turns out the book was half right, if this map is to be believed.

On an actual mine map mentioning Sarah it would appear that Frick's Maxwell mine mined out the coal, though the nearby Hustead Seamans may have mined some of it, depending on the area of the original Sarah mine.
