The Lightning Field (1977) is a land art work in Catron County, New Mexico, by sculptor Walter De Maria. It consists of 400 stainless steel poles with solid, pointed tips, arranged in a rectangular 1 mile × 1 kilometre grid array. It is maintained by the Dia Art Foundation as one of 12 locations and sites they manage. While the work's title, form, and best-known photographs may suggest the installation attracts lightning strikes, in fact these happen rarely.
