Next stop on the microterrain World Tour, this synthetic terrain represents a small area of Western Antarctica.

Geologically, West Antarctica closely resembles the Andes mountain range of South America. (which comes later on the tour!)
The most common rocks in West Antarctica are volcanics formed during the Jurassic period. There is also evidence of volcanic activity, even after the ice sheet had formed.
From a landscape erosion perspective, this area of Antarctica is fairly inactive, the major factors being cliff-face shearing due to the extreme low temperatures, plus of course glacial movement of the ice-sheet... Everywhere else, it's a thick blanket of permanent snow.
This simulated terrain attempts to capture all of these aspects within a small area... cliff-shearing terraces, ancient volcanics (there's a big crater), some directional glacial erosion and thick wind-drifted snow everywhere else...
