A stretch of the northern shore on remote Yttygran Island, 82km off the coast of Alaska, has become a macabre tourist destination. Massive whale jawbones, ribs and vertebrae stand horizontal in the ground forming an eerie alleyway. It’s generally agreed that the site dates back to the fourteenth or fifteenth century, but whether it was a sacred spot for native tribes to meet or simply a gathering place for mass slaughter, no one knows.
