Designated a national monument on January 17, 2001, and managed by the U.S. Bureau of Land Management in conjunction with The Friends of Pompeys Pillar, it consists of only 51 acres (21 ha), making it one of the smallest National Monuments in the U.S. The community of Pompeys Pillar lies just east of the monument.
