Beams and sunlight at the Redridge Steel Dam
near Houghton, Michigan. This is one of only three such steel dams built in the United States. It was built in 1901 to provide water to two copper mills nearby, on the shore of Lake Superior. It has been sitting untended for nearly 100 years, but it's still strong and solid. If you like my photos, please visit my photo store: David Clark Photography
