Summits of most mountains also have polar climates, despite being in lower latitudes, due to their high elevations. The highest mountains of the Rocky Mountains, Alps, and the Caucasus have tundra climate. Some mountains of the Andes, the Saint Elias Mountains, and most mountains of the Himalayas, the Karakoram, the Hindu Kush Range, Pamir Mountains, the Tian Shan Mountains, and the Alaska Range also have ice cap climates at extremely high elevations, in addition to tundra climates at relatively lower elevations. Only the summit of Mount Rainier has an ice cap climate in the Cascade Range.[citation needed]
