“As the Copper Range railroad turns north from Calumet and heads out to the mines along the Allouez gap, it first passes by the town and mine at Centennial. As we follow the same route today – now a snowmobile trail – we pass by the the mine’s remains. In the distance we could make out the collar house to Centennial No. 2, a rather large structure used by C&H in the ’40s. Now its sits forgotten, its rock house long demolished and it’s rock pile completely hauled away. As we continued our walk, we quickly noticed something else in the distance, buried in the trees. It was a structure, at least what was left of one. It took the form of a giant free-standing wall of red sandstone capped by a cycloptic window frame in it’s peak.”
