As Andy Goldsworthy launched his nine-month project to build a now-you-see-it, now-you-don’t “Walking Wall:” at the Nelson-Atkins Museum, I began to drop by from time to time to watch its progress. The grounds of the Nelson’s sculpture park, now including a green space to the east, across Rockhill Road, became a laboratory for Goldsworthy’s hand-made experiments in landscape, natural phenomena, and conceptual art. I wrote about the project early on for KC Studio magazine (find that one here). After the wall’s completion, I wrote another piece for the Art Newspaper, the global journal. The gallery above includes some of my favorite photos from the site visits.
