Nancy Holt developed the idea for her landmark earthwork Sun Tunnels over three years between 1973 and 1976. Part of the process involved using cardboard tubes to model potential configurations for Sun Tunnels and then photographing these models to understand the shifting shadows and scale of the earthwork. In these photo study collages from 1975, we see Holt experimenting with the configuration of the constellations cut into the tops of the tunnels and the orientation of the tunnels to the sun. Each group of images simulates the effect of the shadow patterns cast by the tunnels at different times of day.
Written in the margins of each photo study collage are notes about the orientation, the time of day and year, and the constellation Holt was testing in each series. Through this expansive series of collages begin to see patterns emerge in Holt's studio practice—illustrating her systematic approach to making sculpture, directly informed by her background and interest in natural science, photography, and light.
