MARQUETTE — Mining engineer and local author Allan Koski will present an online slide show featuring his recent book release: “Empire Mine and the Cascade Range” at 6:30 p.m. Eastern time Wednesday. The book tells the story of life on the Iron Range through written voices, images and detailed events from 1844 to the idling of the Empire Mine in 2016.

An in-person book signing will take place from 11 a.m. to 1 p.m. Eastern time Saturday, Feb. 13, at the Marquette Regional History Center.

Recently retired from Cleveland-Cliffs after a 44-year career primarily at the Empire Mine, Koski has authored numerous professional papers and published articles, including a previous book. He is chair of the advisory board at the Michigan Iron Industry Museum, appointed by Gov. Gretchen Whitmer, in the seat representing Michigan’s mineral industry.

During his presentation, Koski will review the lifespan of the Empire Mine in the context of mining history on the Marquette Range, focusing on several important events that shaped the Iron Range.
