Mount Erebus in Antarctica is one of the most active volcanoes on earth.
The region averages fifty-eight degrees below zero in the winter and on an especially balmy summer day the temperature can nudge toward four below. Combine those frigid temperatures with hot gases escaping from ground vents around the volcano, and massive ice structures form, towering forty to fifty feet high.
They’re an oddly beautiful sight in such an unforgiving landscape.
And they exist because of opposite forces coming together.
