I like to think there are trolls with poles underneath. If there were fish, what would they look like? Maya Lin's gorgeous and sensual Storm King Wavefield, above, is awash in living contradictions. Grass swells like water. Ocean waves mimic mountain ridges. An artist-designed tide flows to nowhere. Weeds, waves and rows of distant trees part like a classic landscape painting into fore, middle and background. And everywhere, shade upon shade of mysterious purple rust. I crave this beautiful decay, before the white.
