The cold mountain above Frost Cavern has puzzled geologists by surviving millions of years in a windswept place where it should have long ago been whittled away by erosion. This mountain lacks an official name, for its peak has long been impassable to human settlement and travelers, although Frost Cavern, while cold enough for ice pokemon from higher on the mountain to prosper, remains a well-traveled route. Bergmite therefore have rarely been observed in their natural habitat, and it was not until Kalos' people had run out of distant lands to explore that they finally surveyed the strange and inexplicably resilient peak in their own homeland.

The answer to its survival, however, is not geological but biological, for its Bergmite population has triumphed in a long war against the slow processes of nature. Bergmite have long been known for their ability to repair cracks in their own ice, but only with this recent observation have they been seen doing the same to their mountain home – and with it, their potential was revealed to the modern world.

Climate change threatens many cold lands around the world, and Bergmite have been shipped en masse from their frozen home, in such numbers that Kalos' own population can not breed fast enough to keep up. In some places, they are put to work repairing permafrost melted by increasingly warm weather; in others, they protect ancient cities, rock formations, and other tourist attractions in climates endangered by erosion. The city-states of modern Kalos have sought to bring about measures to limit and regulate Bergmite exports, for they fear that erosion would irreparably damage the route through frost cavern far before it destroyed the mountain above it; however, disputes over the mountain's sovereignty have so far prevented any effective action.
