At California Environmental Protection Agency, one can find the four monolithic stones called Sacremento Stele done by Beverly Pepper. They were sculpted from Pietra Serena stone. Her daughter, Pulitzer Prize-winning poet, Jorie Graham, provided the text and images etched on the surface of the stone sculptures. The benches are made from stone quarried over 120 years ago for the construction of the San Francisco Ferry Building, but the architect at the time rejected them and left the stones to age in the field. It represents all that the California Environmental Protection Agency advocates, and creates a beautiful oasis for quiet contemplation.
