Carbon Sink: What Goes Around Comes Around, installed at the University of Wyoming in late 2011, "consisted of a 36-foot-wide circle of logs from beetle-killed trees, arranged in a whirlpool pattern around a pile of coal. ... In May 2012, however, just after most students left campus,
Carbon Sink quietly disappeared."
