More than 4,000 people arrived at what is believed to be the world's largest post-apocalyptic festival.
Wasteland Weekend, which is inspired by the Mad Max film franchise, aims to mimic a dystopian society.
The over 18s event, held last weekend in the Californian desert, costs around £170 to attend and guests are encouraged to stick to a "post-apocalyptic dress code".
The festival takes place in the Mojava desert, near a defunct Nevada nuclear test site that was used during the Cold War.
To buy anything from makeshift shops, attendees have to barter for goods with themed bottle caps instead of cash.
According to the Daily Star , festival-goers have the option to cruise around in Mad Max-style vehicles.
Alternatively, they could battle it out in the Death Guild Thunderdome.
In this arena, revellers charge at one another with replica weapons and padded paddles.
Unlike a real dystopian environment, the setting has plenty of facilities and entertainment.
DJs were on hand and live bands and fire performances kept the atmosphere lively.
Wasteland Weekend has been running since 2010.
One of the founders, Jared Butler, spoke to Mojave Desert News about why the idea has been such a success.
He said: “We have a broad demographic in terms of ages, backgrounds and interests.
"People are drawn to the event for many different reasons and we didn’t want to set the barrier to entry so high that they couldn’t attend.
“If they only want a little bit of immersion, they can stay in the camp area.
"For the fully immersive experience there is still the city behind the gates.
“It’s not about making everything look great, it’s about the experience we can give to the attendee.
“When you’re out there and everything looks different, you do get this sense of escape, that’s one of the things people gravitate to about the event.”
