The Story of the Hillside Letters

Cowboy Hill in Rapid City
You might have seen the giant letters near Vermillion (USD), near the School of Mines campus in Rapid City and by Spearfish. A big "C" is also on a hill above Chadron State College in Nebraska, just south of the Pine Ridge Reservation. I wasn't aware that such markings are fairly common throughout the West, and quite rare in other parts of the world.
A new book titled Hillside Letters: A to Z tells the stories of the letters. The author, Evelyn Corning, found them from Arizona to Texas. She missed the Vermillion site, but did a nice job on the "H" which represents Black Hills State University. The school hired three students to construct it in 1956. They used handcarts to get the concrete to the top of the Lookout Mountain. Freshmen used to whitewash it, sliding around it with their bodies, as a Swarm Day activity. But in the 1970s they used the wrong kind of lime and over 100 students received chemical burns. That stopped the whitewashing.
The SMD on Cowboy Hill near the School of Mines campus in Rapid City is much older. The college declared a school holiday in October of 1912 to give 65 students and 10 faculty the time to lay out the M. They used picks, shovels and horse-drawn plows. Townspeople watched from down below with spyglasses, opera glasses and binoculars. The photo above shows students carrying a barrel of whitewash up the hill. The S and D were added in 1953.Cowboy Hill was sold for development last year but the SMD and a greenspace around it will be preserved.
