Thousands of Burning Man attendees were forced to trudge through mud – many barefoot or wearing plastic bags on their feet – as flooding from storms swept through the Nevada desert.
Organisers closed vehicle access to the counter-culture festival on Saturday and revellers were urged to shelter in place and conserve food, water and other supplies.
Vehicle gates will be closed for the remainder of the event, which began on August 27 and was scheduled to end on Monday, according to the US Bureau of Land Management, which oversees the Black Rock Desert where the festival is being held.
More than half an inch of rain is believed to have fallen on Friday at the festival site, located about 110 miles north of Reno, the National Weather Service said. At least another quarter of an inch of rain is expected on Sunday.
The Reno Gazette Journal reported that organisers started rationing ice sales and that all vehicle traffic at the sprawling festival grounds had been stopped, leaving portable toilets unable to be serviced.
Officials have not yet said when the entrance is expected to be opened again, and it was not immediately known when celebrants could leave the grounds.
The announcements came just before the culminating moment for the annual event – when a large wooden effigy was to be burned Saturday night.
Many people played beer pong, danced and splashed in standing water, the Gazette Journal said.
Mike Jed, a festival-goer, and fellow campers made a bucket toilet so people did not have to trudge as often through the mud to reach the portable toilets.
“If it really turns into a disaster, well, no-one is going to have sympathy for us,” Mr Jed said. “I mean, it’s Burning Man.”
