Locator (Cracked Window) was one of the earliest works Nancy Holt created in her Locator series. Positioned by a window in Holt’s New York Studio, a steel Locator captures a view of the cracked window on the slanted glass ceiling below. The crack forms a circle with radial slivers protruding outwards, a sun-like shape similar to those featured in Holt’s public artworks. The circular shape of the crack is accentuated by the circular framing of the Locator’s view, casting an aesthetic light onto an ordinarily unfavorable slice of city life.

Installed in the shared studio space of Nancy Holt and Robert Smithson's loft in New York City, Locator (Studio Corner) is one of the earliest Locator works that Holt created, and the first that solely engaged interior space. In contrast to other early Locator works that Holt created in her studio—which concentrated vision on preexisting details in the built environment outside Holt's studio window—Locator (Studio Corner) focuses vision on a black shape that Holt painted in the corner of the room.

Locator (Exhaust Pipe) was one of the earliest works Nancy Holt created in her Locator series. Directed out of a window in Holt’s New York studio, the view from this Locator features an exhaust pipe, perfectly encompassed by the aperture. The illuminated circular opening of the pipe is reiterated in the circular outline of the Locator view; both create tunnels of vision, holding light within their shapes. Holt's fascination with perception and vision are embodied in this simple intervention in her studio.
