It is the enduring legacy of historic mining, a vestige of the Keweenaw Peninsula’s heyday as the world’s greatest source of copper. For more than 100 years, roughly 50 billion pounds dumped in a pile so large it once extended a half mile into the lake, has been slowly, inexorably, eroding south. As they move, the stamp sands swallow the coast and smother the lakebed, transforming miles of shoreline into a lifeless, apocalyptic hellscape that people liken to the surface of the Moon. It is a slow-motion ecological disaster unfolding across a century. |
