Ice Cave ~ Mt Erebus, ANTARCTICA
Usually to cold is cold and the hot is hot. Rarely do the two meet.
Here in an ice cave in Mt Erebus, Antarctica the Antarctica ice meets the the hot volcanic rock.

"An ice cave on Mt. Erebus, Antarctica, where steam escapes from cracks in underlying volcanic rock, melting out chambers in overlying ice.
As warm moist air condenses, it forms ice crystals which grow on cave walls in strange forms.
On the right is volcanologist Alexander Gerst, inspecting volcanic ash which coats the walls of the largest room. Caves like these are considered good analogs for the kinds of environments which could harbor life on other planets, such as Mars.
This photo was taken in 2005, and just last November, Alex returned from 165 days on the International Space Station."
