There’s an exhibit of site-specific earth art installations going on at the Royal Botanical Gardens in Ontario, Canada. Artists from all over the world have come to install unique environmental pieces, which will be on view until October 13. There are sod ramps, floating sculptures, and other Andy Goldsworthy-esque pieces. There’s also a tumblog of installation photos, which shows how some of the pieces were constructed and installed.
