Life in the extreme south and north is much different than the rest of the world. The sub-zero temperatures require a careful and meticulous approach to survival, and produce some of the most daring expeditions. However, some of the icy frontiers remaining to be pioneered are the art and skill of arctic surfing.

These penguins are in danger of getting pulled down by the undertow caused by big surf.

Here is a picture of some explorers on Kagalaska Island resting from a long day of exploring.
