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
