Gradient/Suspect Terrain (Seasons of the Sea ' Adrift'), Yerba
Buena Gardens, San Francisco, CA, 1993.
This work is
a permanent public work that refers to the origin of the coastal California
landscape from sea floor sediments and the accretion processes of
plate tectonics. The sedimentary material within the structure was
gathered from the sea floor about 4 miles (6km) off the California
coast. Currently plants are growing inside originating from seeds
encased in the sea floor sediment. A recent project, Yerba Buena Complex, 2008, extends and contexturalizes Deep Gradient/Suspect Terrain.., further into the Yerba Buena site.
