University of Arkansas Senior Walk
Started by the Class of 1906, Senior Walk contains the names of graduates, beginning with the first class in 1876; the original class is inscribed at the foot of Old Main steps. It is a unique tradition among American colleges and universities, covering over five miles of paved walks throughout the campus. Originally stamped by hand, the names are now etched by a machine known as the Senior Sand Hog, invented in 1986 by University Physical Plant employees. Over 140,000 graduates are now listed. The tradition is as unique as the Hog Call, as there is nothing like it at any other college in the world.
