Горло Барлога, Karst cave in Karachay-Cherkessia, Russia.
The cave entrance leads through a 73-meter vertical shaft, followed by cascading passages and deep wells reaching depths of up to 170 meters.
A team of speleologists from Rostov-on-Don, Cherkessk, and Donetsk discovered the cave in 1994, initially exploring it to a depth of 330 meters.
The name Gorlo Barloga references The Lord of the Rings character Balrog, as the cold stream flowing through the narrow entrance reminds of drinking.
Access to the cave requires specialized equipment including hydrosuits, with water temperatures maintaining at approximately 3 degrees Celsius throughout the system.
At 839 meters deep and 3000 meters long, this cave system represents the deepest karst formation in Russia, with marbled limestone walls displaying blue-gray and black stripes.
