Kristoff and Sven were walking down the rocky mountain path under the bright glow of the northern lights.

克斯托夫和斯特在北极光的指引下，沿着崎岖的山路前进。

And then climate change decreased rates of snowfall in the rocky mountains and droughts have been making everything much worse.

然后，气候变化减少了落基山脉的降雪率，干旱使一切变得更糟。

Now the rocky mountain grey feeds at night.

今晚这只落基山小灰能吃的肚儿圆。
