1991 marked the first year that the event had a legal permit, through the BLM (the Bureau of Land Management). 1991 was also the year that art model and fire dancer (and later Burning Man's first art director) "Crimson Rose" attended the event. 1992 saw the birth of a smaller, intensive (about 20 participants the first year; about 100 in years two and three) near-by event named "Desert Siteworks", conceived and directed by William Binzen and co-produced (in 1993 and '94) with Judy West. The annual, several weeks-long event, was held over summer Solstice at various fertile hot springs surrounding the desert. Participants built art and participated in self-directed performances. Some key organizers of Burning Man were also part of Desert Siteworks (John Law, Michael Mikel) and William Binzen was a friend of Larry Harvey. Hence, the two events saw much cross-pollination of ideas and participants. The Desert Siteworks project ran for three years (1992–1994). 1996 was the first year a formal partnership was created to own the name "Burning Man" and was also the last year that the event was held in the middle of the Black Rock Desert with no fence around it.
