Out for a walk in Fort Mason, army-post-turned-park in San Francisco, we came upon this by accident. Yikes! What happened here? Is this a practical joke? No! Those boulders would be too heavy. What's holding them up? Are they real boulders or hollow plastic casts? Why are those guys hanging out where boulders could fall on them?
We had not been warned to be on the lookout for sculpture. This one is entitled Ideas of Stone and was created by Giusepe Penone. The boulders are real. The tree is a bronze cast.
An article on the website of the Golden Gate National Parks Conservancy says, "Penone uses objects from the natural world to document the intertwined relationship between humans and nature," and "Penone’s earliest works included site-specific sculptures."
So, Penone has a lot in common with Andy Goldsworthy, four of whose sculptures can be found in the Presidio, another army-post-turned-park in San Francisco: Earth Wall, Spire, Tree Fall, and Wood Line.
The article also says another work by Penone has been installed elsewhere in Fort Mason. I guess we'll have to take another walk.
