Organisers of the event in the Nevada desert have asked people to stagger their exits after thousands were stranded over the weekend
Burning Man attenders began their slow exodus from the campsite in the northern Nevada desert after muddy roads that left tens of thousands of partygoers stranded for days dried up enough to make travel possible.
Festival organisers said they started to let traffic flow out of the main road around 2pm local time on Monday – even as they continued to ask revelers to delay their exit to Tuesday to ease traffic. As of Monday afternoon, they said about 64,000 people remained at the festival site.
