Narrator: Thomas Woodruff’s oeuvre consists mainly of subtle earth sculptures, most of them on Hawaii, where he grew up. ”Louisa” is a grassy knoll, hardly noticeable if you’re not actually looking for it. Like a hidden treasure, it is available to all, but can only be experienced by those who know where to find it. It is a work in perpetual change. The hill is altered by the trampling of feet and the weight of snow in winter. The grass goes yellow and turns green again. Woodruff died in 1988, and ”Louisa” was his last work.
