Old Deetz Slate Mine Quarry

About

In operation from 1854-1911 under the direction of Levi Deetz, the quarry produced high-quality roofing slate for many of the significant building projects in the surrounding area including Duluth. In 1892, 'Slateville' was created to provide housing for workers in the quarry. The quarry was mined to a depth of approximately 100 ft and contained tunnels. Although presently filled with water, the steep quarry walls are visible and an historical marker is at the site.
