Burning Man is a week-long large-scale desert event focused on "community, art, self-expression, and self-reliance" held annually in the Western United States.[1][2] The event's name comes from its ceremony on the second to last night of the event: the symbolic burning of a large wooden effigy, referred to as the Man, the Saturday evening before Labor Day.[3] Since 1990, the event has been at Black Rock City in northwestern Nevada, a temporary city erected in the Black Rock Desert about 100 miles (160 km) north-northeast of Reno. According to Burning Man co-founder Larry Harvey in 2004, the event is guided by ten stated principles: radical inclusion, gifting, decommodification, radical self-reliance, radical self-expression, communal effort, civic responsibility, leaving no trace, participation, and immediacy.
