|Ice Cavern (Ice Age)|
This ice cavern was a long passage of naturally-occurring tunnels formed from ice.
After having inadvertently caused an avalanche, three animals, a mammoth named Manfred, a ground sloth named Sid, and a saber-tooth tiger named Diego, with a human baby named Roshan in tow, the latter being brought along by the three mammals so as to return him to his family, hurried into the cave to escape being crushed by the avalanche. The falling snow, however, had blocked the cavern's entrance, trapping the four inside to walk through the cavern and reach the other side.
While walking through the caves, Sid had found a number of frozen creatures within the ice walls, among them were animals that all bore a passing resemblance to Sid, a frozen dinosaur, a frozen carnivorous fish, and even a large frozen alien spacecraft. At the end of the tunnels and slides of the cavern was a cave that humans had settled in at one point, adorning the walls with paintings of animals and humans on the hunt.
The baby, however, was separated from the other three mammals as he slid off on an ice slide, prompting the others to slide after him. As they slid, the three mammals wrecked their way through ice buildup, from upward-pointing icicles to an expansive wall of ice.
On the route taken north to reach Glacier Pass, the ice cavern was expansive, with a number of passages and honeycomb-like divisions, some of which contained a number of frozen animals, among them a frozen dinosaur which had been frozen while pursuing prey, a large carnivorous fish, a number of animals from various ages that all resembled the evolutionary ancestors of Sid and even a massive flying saucer that had become frozen in the ice.
Throughout the caves were a number of naturally formed ice slides, though some of the slides were peppered with icicles that formed upside-down, upward, along with a number of natural drops and pits that led to other slides. The slides eventually led to a large cave that was riddled with a number of human paintings of animals. There were paintings of both contemporary and prehistoric, with the exception of ground sloths.
