Untitled Earthwork (Johnson Pit #30) is a landmark land art project by Robert Morris that transforms an abandoned gravel pit in Washington’s Kent Valley into a monumental sculptural landscape. Created in 1979 as part of the symposium Earthworks: Land Reclamation as Sculpture, the work exemplifies an early and influential effort to use art as a tool for environmental rehabilitation.

Morris reshaped a 3.7-acre post-industrial site by clearing invasive vegetation and carving 16,000 cubic yards of earth into descending concentric terraces, forming an amphitheater-like hill. Planted with rye grass, the sculpted terrain restores the land to active use while inviting public access and gathering. A line of blackened tree stumps – what Morris termed a “ghost forest” – remains embedded in the landscape as a quiet marker of the site’s layered history, from natural hillside to gravel pit and dumping ground.

Drawing on ancient and modern traditions of terracing – from Persian gardens to agricultural landscapes and industrial embankments – Morris conceived the project as a “prototypical act in shaping the earth.” The work challenges conventional ideas of sculpture by using the land itself as both material and subject, merging aesthetics, ecology, and public infrastructure.

One of the first publicly funded land art projects in the United States, Untitled Earthwork (Johnson Pit #30) has since become a valued community space and a touchstone in the history of environmental art. Its significance was formally recognized in 2021, when it was listed on both the Washington Heritage Register and the National Register of Historic Places – an unprecedented distinction for a contemporary earthwork – affirming its high artistic value, historical importance, and enduring relevance in conversations about public art, land use, and environmental restoration.
