The spectacular patterns covering the curved roof and walls of this ice cave look like they were made by a kaleidoscope.
Glacial water causes the brilliant translucent blue colouring in the ice, while the shadowy black sections are frozen volcanic ash.
This otherworldly ten metre high cave is only temporary - every year new caves are formed and old ones disappear as the glacier they lie beneath retreats.
Australian photographer Guy Havell travelled half way around the world to photograph these breathtaking ice caves underneath the Breidamerkurjokull glacier in south-eastern Iceland. SEE OUR COPY FOR MORE DETAILS.
