 In 1931, Everett H. Kimmell, another U.S. Surveyor, found this newer stone had broken too and he replaced it with a brass disc marker set in concrete.In 1962, the Bureau of Land Management and the Bureau of Indian Affairs poured an elevated concrete pad around the 1931 brass marker; this pad included the state border lines and names in tile.The monument was completely rebuilt in 1992, and the 1931 brass marker was replaced with a disc shaped aluminum-bronze plate set in granite.
