Svartifoss (Black Fall) is a waterfall in Skaftafell National Park, Iceland, framed with dark lava columns, which give rise to its name. Svartifoss stands out thanks to the very pronounced hanging hexagonal basalt columns underlying it that resemble organ pipes. Its bottom is full of piled up sharp rocks that have chunked off. These columns were formed inside a lava flow which cooled extremely slowly, giving rise to crystallization.
