Houghton-Douglass Falls is a waterfall in the U.S. state of Michigan. At 110 feet (34 m) from the top to its base, it is Michigan's tallest waterfall. It is located in the state's Upper Peninsula between the villages of Laurium and Lake Linden just off Highway M-26. Prior to 2018, the waterfall was privately owned and access to the waterfall was restricted due to its dangerous geological makeup. The waterfall is situated in a deep gorge that is flanked by sharp loose rock. Multiple deaths have been reported at this location; the most recent one was in September 2011. Houghton-Douglass Falls is named for Douglass Houghton, Michigan's first geologist. and Columbus Christopher (C.C.) Douglass, Douglass Houghton's cousin who is also important to Copper Country History.
