Missoula Ranch Locators - Vision Encompassed (1972) by Nancy Holt is a site-specific sculpture created on ranchland near Missoula,  Montana. Eight Locators, T-shaped structures made from galvanized steel, were arranged in a circular formation and aligned with the compass directions outdoors, developing from experiments Holt conducted in her studio the previous year.

In this 1972 drawing, Nancy Holt develops an idea for an outdoor Locator work for a site she referred to as the “Village Triangle,” at the intersection of West 12th Street and Greenwich Avenue in New York City. She indicates that the three Locators are made of two-inch galvanized steel pipe and should be installed 40 feet apart, set in concrete in the ground. This site-specific sculpture remains unrealized.
