Stunning Russian fire and ice caves
The bizarre combination of freezing cold winter and active volcanos are married together in these stunning photos by Denis Budko. The two seemingly opposite elements are found existing harmoniously in the cave of the far east peninsula known Kamchatka in Russia. Until 1991, the caves were strictly off limits to foreigners. But ever since the fall of the Soviet Union, fantastic natural wonders like this have been shared with the rest of the world.
