Nancy Holt created Moon Book in 1972—shortly after the first Moon landing in 1969 and the additional five lunar landings between through the end of 1972—a period when the Moon loomed large in the collective imagination. The collaged fourteen page book brings together disparate relationships and perceptions of the Moon over a large span of time.

Holt designed ​Dark Star Park i​n concert with the development of the site as a whole, integrating landscaping and sculptural features to encompass the neighboring building and adjacent traffic island. Concrete spheres are interspersed throughout the park, visible through tunnels, reflected in pools of water, and framed in the carved-out hole of another sphere. Every year on Dark Star Park Day people gather to watch the shadow alignment.
