The salt mines lie 650 feet under the surface of Yekaterinburg, Russia.
Hundreds of feet below a Russian city is something so trippy and mind-blowing, it's hard to believe it's actually real. What was once a salt mine is now an insanely colorful, psychedelic underground cave, an effect caused by many natural layers of mineral carnallite.
Carnallite creates swirls on the colored rock,ranging from yellow to white to bold blues and reds. It turns an average old salt mine into a site of particular interest for potential tourists, but unfortunately, it's also totally off limits without permission from the Russian government. Luckily, we've got photos of the mine below.
The carnallite has caused an abundance of colorful swirls to appear on the rock.
Though this is a highly-sought after tourist spot, it's only accessible with a permit from the Russian government.
Mikhail Mishainik, a Russian photographer, was able to obtain the permit and capture these photos.
It's not a safe job, either: The photographer and his crew risked exposure to gas and landslides while inside.
Still, it might have been worth the risk for these trippy views.
"The mines are huge and stretch many kilometers in width and length, a single tunnel can be over four miles long," the photographer said in an interview." It is hard to describe how it feels being so far down, you lose all track of time and the air is very dry, you always feel thirsty."
It took him over 20 hours down below to capture these images, and we're glad he did: Who knew something so amazing could occur in something as innocuous as an abandoned salt mine?
