Arctic Spires

The Arctic Spires are an above-water biome that will be featured in Below Zero.

Description
The concept art displays a frozen landscape, with a flat ice sheet broken up by huge spires of ice jutting up from below. It would appear the sea level has dropped since the ice spires formed, or the spires were thrust upwards, as the spires each have a large mass of ice a short way up above the floor, implying that this was once the level of the surrounding ice sheet.

It is currently in a very early blocked out stage in Below Zero.
