The sculptures and drawings in Maya Lin’s self-titled exhibit at the Heinz Architectural Center in Pittsburgh are notable for their sinuous shapes and spare beauty. But they also invite us to contemplate our relationship with the natural world, as the pieces are all representations of environmental features, including a recycled-silver sculpture of the Hudson River, called “Silver River” (shown), and a plywood version of the Caspian Sea that reveals the extent of the water’s depths below the surface. Lin created one installation just for the show: a series of pins mounted on a wall that depict Pittsburgh’s three rivers—the Ohio, Allegheny, and Monongahela. That Lin wants to reveal nature’s often-obscured beauty comes as no surprise, given her reputation as an environmental advocate. Through May 13. •
