SHANGRI-LA, mythical kingdom synonymous with Utopia, was the brainchild of American novelist James Hilton in his 1933 bestseller Lost Horizon. Hilton's inspiration came not from any personal travel experience in Tibet, but from articles by American botanist Joseph Rock, who lived in the Khams region (the area flanking the present-day border between Tibet and Sichuan Province) from 1922 to 1949.
