Roosevelt establishes Superior National Forest creating framework for future Boundary Waters

President Theodore Roosevelt establishes Superior National Forest in northeastern Minnesota through executive proclamation, protecting the largest expanse of wild land east of the Mississippi River across 3.9 million acres. The forest will become the centerpiece of a century-long dispute over mining rights, eventually encompassing the Boundary Waters Canoe Area Wilderness. This foundational designation will be invoked 115 years later when opponents of copper-nickel mining argue Roosevelt's conservation legacy demands protection.
