Burning Man is an annual gathering that takes place at Black Rock City—a temporary community erected in the
Black Rock Desert in
Nevada. The event is described as an experiment in community and art, influenced by 10 main principles, including "radical" inclusion, self-reliance and self-expression, as well as community cooperation, gifting and
decommodification, and
leaving no trace. First held in 1986 on
Baker Beach in
San Francisco as a small function organized by
Larry Harvey and a group of friends, it has since been held annually, spanning from the last Sunday in August to the first Monday in September (the U.S.
Labor Day); for example, Burning Man 2015 took place August 30 – September 7, 2015.
