The annual Burning Man festival, which sees the construction of a small tent-opolis in Nevada’s Black Rock Desert each year, got underway Sunday, bringing out devotees of the bacchanal—self-described “Burners”—clad in the usual Barbie-meets-Mad Max fantasy looks. (After all, the festival even offers a custom tailoring table for any inevitable wardrobe malfunctions.) For the uninitiated, the festival, which was founded in 1986, has garnered a reputation as a hedonistic spectacle for prominent Hollywood and Silicon Valley figures, a weeklong spirit quest of sorts during which participants make “theme camps” in the temporary Black Rock City. (This year’s themes include such heady titles as “)*(Aloha = H’Aloha,” “404: Village Not Found,” and “”#Octothorpe.”) It has earned so much cult appeal that its attendees regularly post throwbacks to previous years’ festivals in the lead-up to the latest installment, often with lengthy postscripts about the experience. Last year, supermodel and actress Cara Delevingne was in the crowd, as was Vikingsstar Gaia Weiss; this year, Paris Hilton has made the pilgrimage yet again. Cell phones might be verboten at Burning Man, but what’s the point in having a geotag if you’re not going to Instagram the experience? Here, see a few of the best moments from Burning Man 2017 thus far.
