The country’s hautest festival may be losing steam — and the very soul of Burning Man may be at stake.

Earlier this month, big changes were announced for Burning Man, the 50,000-person melting pot of social mores in Black Rock City, Nevada — a jaw-dropping annual carnival of coitus, costumes and contraband — that’s become more over-the-top bacchanal than down-to-earth bohemian in recent years.

Vowing to return to its roots and stamp out “negative cultural trends,” organizers have booted upscale Camp Humano (a Fyre Festival-style camp) and promise to regulate the “Instagram culture” going forward.

Burning Man CEO Marian Goodell called out the relentless Instagram posts and wayward camp, whose negative effects fly in the face of Burning Man’s “10 core principles,” including decommodification.

“Posts of gratitude cross referenced with hashtags started off slow and innocently enough, but are now wildly out of control,” Goodell writes on her blog.

“Failing to make clear what behavior is unacceptable has compounded the problem. I recently heard rumors of more than one product or business launch happening on playa [the temporary city created by attendees] in 2018. Seriously, people. This really isn’t Burning Man.”

Veteran Burners are thanking the “Playa” gods for some action against Camp Humano.

“[It’s] a very long time coming. They’ve been agonizing over how to rein in the truly egregious camps,” one local Burner tells The Post.

“It’s been a problem and topic of conversation for a few years. But only this past year was a camp so bad that they had to take drastic action,” says the Burner, adding that she doesn’t know of anyone who’s not behind the latest push to save Burning Man’s soul.

“I think it’s a great thing that they are thinking about how to preserve culture. The Burning Man culture is both amazing and extremely unique — it’s a big part of what makes the event so fantastic,” says RCT, a longtime Burner who provided his Playa name, adding that he’s not holding his breath for meaningful change. “But I expect these specific changes to have only a very minor effect,” says RCT, who works in software in the “default world.”

RCT pleads for a return to the good old days.

“[Some] people are not even trying to live by the 10 principles of Burning Man,” RCT rants. “If people are there to get cool Instagram selfies, or to spot celebrities or merely to get trashed and party, they are missing out on what makes Burning Man incredible, and in fact actively working against the unique culture that makes it so good in the first place.”
