Michigan Crystal Falls
Crystal Falls probably has a larger number of developed mines in its
imediate vicinity than any other town in the Upper Peninsula, and as soon as the depression in iron permits of their working, the place must necessarily assume its proper position among the towns of Northern Michigan. , The Youngstown Mine is located in a cedar swamp that extends east and west between two ranges of moderately high bluffs that rise to the south and to the west. Running east along the north margin of the swamp is Bertha Creek, which a little further on flows into the Paint-river. Along the south side of the swamp is the mine, extending entirely across the northeast quarter of the southeast quarter of section 19, township 43, range 32, and east into section 20. The ore is a dark brown hematite, of medium hardiness, averaging about 60 per cent in metallic iron, 30 in silica, but is too high in phosphorus for a Bessemer. It is said to contain an amount of alumina, magnesia, and lime in quantity that should render it suitable for working easily in the furnace without additional flux.
