In April of 1886, a group of coal miners working a mine in the Broad Top Hills of central Pennsylvania came upon something both puzzling and remarkable. While extracting coal, they uncovered a stretch of slate that appeared to have a series of crudely carved human faces chiseled into it. They found the discovery remarkable enough that they removed it and showed it to their employers and the press. It caused quite a stir, being reported in the Lewistown Gazette on April 25, 1886. The figures were described as looking as if they were “cut with a graver’s chisel” and bearing the images of human faces with the “chin, mouth, cheeks, forehead, and eyes clearly delineated.” Given the depth of the coal seam and the era when it would have been laid down, the carvings would have had to have been made millions of years before any of humanity’s ancient ancestors were traipsing around and engaging in stonework, to say nothing of having the technology to produce tools capable of performing such work. So how was this to be explained?
