Amazing photos have appeared of a psychedelic looking cave underground within the miles of abandoned mines beneath Yekaterinburg, Russia. For reference, Yekaterinburg is in southern Russia about 1100 miles east of Moscow or about 1600 miles northeast of Sochi. Layers of carnallite -- a mineral used in fertilizers -- band the tunnel walls, producing these technicolor masterpieces. Carnallite is a mineral that forms in very specific conditions, typically forming from some sort of evaporative process over a long period of time.
A small portion of the carnallite mines remain in use, but most of the passageways are now closed and off-limits to the public without a special government permit, according to photographer Mikhail Mishainik who took the pictures below.
