“The largest letter "M" in the world!”
The Platte Mound M is the letter "M" written using whitewashed stones on Platte Mound about four miles east of Platteville, Wisconsin. It is the largest letter "M" in the world. The letter is 241 feet (73 m) high, 214 feet (65 m) wide, with legs 25 feet (7.6 m) wide. University of Wisconsin-Platteville students Raymond Medley and Alvin Knoerr worked at a Colorado mine in the summer of 1936, where they saw a large letter "M" on the side of a hill that signified mining. They believed that a larger "M" should be written on the Platte Mound to represent Platteville miners.
