Frost Pocket

Born of Ice: The depressions you are walking through are known as frost pockets. Made when huge chunks of ice were left behind at the end of the ice age, frost pockets can be much cooler at the bottom than at the rim since cool air is often trapped in the depressions. They can have frost at the bottom even into early summer! The lack of tall trees, dry soil, and frequent frosts allow rare and highly adapted plants and animals to thrive here.
