Tucked in the rolling hills just beyond Geyserville, California, the Olivers have commissioned over 18 works of art on their property. Their only direction to artists has been to "respond to the land."
Richard Serra's "Snake Eyes and Boxcars", 1990-1993 are six pairs of forged, hyper-dense corten steel blocks set at intervals across a valley to demarcate where the slope of the landscape drops most severely and provide points for viewing and surveying the landscape.
Ann Hamilton's The tower, 2003-2007 is a cast concrete silo with double spiral staircases, open to the sky at the top, with a 3' pool at its base—a singular acoustic space to house site-specific performances.
Bruce Nauman's "Untitled", 1998-99 measures the contour of the landscape via a cast concrete stair with 30" square treads, each rising at a specific height particular to the incremental change in grade for almost a quarter of a mile.
