In summer, the sandstones are perfectly camouflaged into the color of the dry golden grass and dirt.
And then one day, when tangobaby and I had a conversation about the genius of Andy Goldsworthy’s art, she told me that one of his works was right here in my own back yard. I’m talking about Andy Goldsworthy’s 2001 sculpture “Stone River” , a 320-foot-long sandstone sculpture set in a 3 ½ foot channel in front of Stanford University’s Cantor Center for Visual Arts.
Andy Goldsworthy is a British sculptor who uses elements of nature and shapes them into art that fits perfectly into its environment. All his works are beautifully documented in his books and his DVD "Rivers and Tides".
Some of his art is impermanent, meant to be melted by the sun or washed away by the waves of the sea or rush of a river. Other works, like “
"The ephemeral work is the soul of my art. That is the food. All these other things that I do -- the permanent pieces, the installations in museums -- are like breathing out.” 
Goldsworthy used sandstone from a repository of materials salvaged from
"The idea of stone that was once a building returned to the ground, back into the earth, for a work that is about flow, movement and change, it was perfect. It was really perfect.”
His unflagging dedication to his work is legendary. He lamented that he had to interrupt his time with the sculpture in order to be guest of honor at the inauguration of the sculpture.
"I've stayed here watching it the whole day. I've seen incredible changes (now) there's a gap in my understanding of the piece… If you had to describe my work in one word, it would be 'time'."
Then when I recently happened to drive by the location after a good rain storm, when the grass was bright green, the sculpture took on a completely different nature. It looked cool and lush, complementing its environment rather than melting into it.
I’m not sure if Goldsworthy has seen this piece in this blossoming state, but if he saw the dramatic changes, he would be want to be here year-round to get a fuller understanding of the piece. Hmm, that might not be all bad; maybe he’ll be inspired to do another work of art.
