Seaman Mineral Museum

The A.E. Seaman Mineral Museum, currently located on the campus of Michigan Technological University in Houghton, Michigan, is the official mineral museum of the state of Michigan and is a heritage site of the Keweenaw National Historical Park. The museum is named for professor Arthur Edmund Seaman, who worked at Michigan Tech in the late 19th and early 20th centuries, and was the museum's curator from 1928 until 1937.The mineral collection was established in the 19th century, and by 1890 numbered 27,000 specimens. The museum currently houses over 36,000 specimens from around the world. Many of these specimens are native generally to Michigan, and more specifically to the Lake Superior region. The Copper Pavilion just outside is home to the Guinness World Record holder for largest boulder of copper weighing 19 tons and pulled from the bottom of Lake Superior.
