Platte Mound M, Hillside letter on Platte Mound near Platteville, Wisconsin.
The stone letter M on Platte Mound stretches 241 feet high and 214 feet wide, with legs measuring 25 feet in width across the slope.
Two University of Wisconsin-Platteville students initiated the construction in 1937 after seeing a similar letter on a Colorado mine hill.
The letter M represents the mining heritage of Platteville and continues to receive maintenance from university student organizations throughout the years.
Visitors can access the site by climbing 266 stairs to reach the summit, which provides views of the University of Wisconsin-Platteville campus.
Students originally marked the letter design in snow during winter 1936, making it temporarily visible before constructing the permanent stone version.
