The Burning Man festival site in Nevada's Black Rock Desert experienced torrential rain over multiple days, flooding the area with mud and difficult conditions. On Monday, organizers began an "exodus operation" to help the tens of thousands of attendees at the site depart as conditions began to dry out. Leaving the remote site still posed major traffic challenges. Attendees spent days sheltering in place amid the rain and mud, navigating the treacherous conditions. Some chose to depart on foot through miles of mud.
