In the Mt. Pleasant - Latrobe portion of the Connellsville Coke Field lies the Mammoth patch. The Colonel J.W. Moore Coke Co. built the mining town in the mid-1880s, and they mined the Pittsburgh seam and coked it in their ovens there. Naturally, H.C. Frick eventually took over Mammoth No. 1 and No. 2 and they eventually had 509 ovens in blast there before shutting the whole thing down in 1927.
The slope portal for the Mammoth No. 2 mine is shown here in it's presently restored state. There is a monument there also to "Heros of the Industrial Revolution," the 116 miners that died in the Mammoth No. 1 mine explosion in 1891. There is some landscaping around the site, and overall it is a very nice memorial that is accessable to the public.

These reconstructed coke ovens are over the hill from Mammoth in Mammoth Park and were part of the Magee coke yard.
