HOUGHTON, Mich. A Michigan Technological University professor has written a book about historic streetcar service in the Upper Peninsula's Copper Country.
Bill Sproule is a professor of civil and environmental engineering at the Houghton school.
His book, "Copper Country Streetcars," was published by Arcadia Publishing Co. earlier this month.
During the early 1900s, copper mining was at its peak in that part of the state. A number of communities sprang up throughout the region, but travel between towns was difficult, because roads weren't paved and became impassable during the winter months.
Streetcar service then popped up, linking communities such as Houghton, Boston, Laurium and Wolverine.
According to the publisher, Sproule's book is 128 pages and features 200 black-and-white images.
