Icebounding

Some lands are cold and baron, and the very air stings your skin. Ranks in this Subskill will increase your ability to survive in a place where existence is pain, and only the strongest (and those with cold resistance) survive. This Subskill bonus is applied to any standard Survival check you make while in a polar environment; however, its bonus can also be applied to other Subskills you may have that work in a polar environment (Such as Tracking when in a Tundra, if you also have a Tracking Subskill bonus.)
