'Underland' by Robert Macfarlane
The author is visiting the decorated sea caves of Norway's western coastline.
'One of the remotest of these painted caves lies near the western tip of the Lofoten archipelago: the island chain that extends for almost 100 miles into the Norwegian ocean at a latitude of around sixty-eight degrees.
The cave's modern name is Kollhellaren, which translates roughly as 'Hole of Hell', and it lies near the tip of the island of Moskenes, on its uninhabited north-western coast.
It is here that 'the red dancing figures exist.....in some of the harshest country in the world.'
