The John Burroughs Association announces the 2010 winner of its annual award, created 84 years ago to honor outstanding natural history writing, a genre perfected by John Burroughs: Michael Welland, for his book Sand: The Never-Ending Story (University of California Press, 2009). In Sand, Welland reflects on the extraordinary story of one of nature's humblest, most powerful, and most ubiquitous materials.
