The United Nations Educational, Scientific and Cultural Organization (UNESCO) named six new natural sites, plus one addition to an existing candidate, to its World Heritage List on June 21, 2013. Mount Etna, pictured here, was one of the newly added sites, along with the Xinjiang Tianshan mountain system in China and the Namib Sand Sea, a coastal desert in Namibia. The Mount Kenya-Lewa Wildlife conservancy in Kenya, was also added as an extension to Mount Kenya Natural Park/Natural Forest, which was designated a World Heritage Site in 1997.
