Fractal Arch, Erebus Ice Tongue Cave, Antarctica
The Erebus ice tongue is the end of a glacier that extends onto the sea ice on McMurdo Sound. A small opening in the tongue leads to an ice cave containing unusual and fragile ice crystal structures. It is accessible only a few weeks a year. Accompanied by a mountaineer, I explored this remarkable environment. When I had him backlight the features with the lamp he was carrying, they came to life in marvelous ways.
