The Monson Maine Slate Company was founded between 1870 and 1880 and operated the majority of quarries and produced what most said to be the finest quality slate in the world - superior to that of Welsh slate. Their primary product was roofing shingles but the Monson Maine Slate Company also produced sinks, switchboards, countertops, flooring, and monuments.
