A. E. Seaman Mineral Museum

The A. E. Seaman Mineral Museum houses thousands of mineral specimens from around the world, featuring displays of copper crystals, rare silicates, meteorites, and fossils within well-lit exhibition cases that showcase the natural diversity of geological formations.

Founded in the early 20th century, the museum has expanded significantly over the decades, growing from a modest collection to become one of North America's leading mineral museums with historical roots tied to Michigan's copper mining industry and academic institutions.

The museum serves as a key institution within the Keweenaw Heritage Sites, interpreting and preserving the technological and cultural significance of the region's copper extraction history while promoting understanding of Earth's mineralogical processes through educational programs and guided tours.

The museum operates Monday through Saturday from 9:00 AM to 5:00 PM, offering accessible facilities, parking for cars and buses, restrooms, a gift shop selling mineral specimens and educational materials, with admission fees ranging from $4 to $9.

Located on the Michigan Technological University campus, the museum features the largest public exhibit of minerals from the Great Lakes area and maintains an active research collection used by scientists studying mineral deposits and environmental factors.
