Minong / Isle Royale has been shaped by human presence for thousands of years. Once an Anishinaabe berry reserve and site for copper mining, the archipelago is now a National Park with limited access, where ecological imbalance grows as human intervention diminishes. Beneath the islands lies a network of abandoned copper mines, contaminated by atmospheric toxins from tailings and industries along Lake Superior, serve as reservoirs of ecological degradation. We propose a constructed geology for surface water remediation. Passive systems engage the basalt’s natural filtration properties and the slopes of remaining mines.
