Well, not quite. The geologic evidence suggests that the area of Central Asia where the Indian plate collided with the Asian plate to create the Himalayas, Pamir, Kun Lun, and Karakoram mountain chains is hundreds of millions of years old. Even so, it is the YOUNGEST area of mountain-building on the planet. "Young" mountains are high, steep, and snowy, whereas "old" mountains like the Appalachians in the eastern US, are quite a bit older, and have been worn down by wind and water erosion.

On K2 mountain, temperatures can drop as low as -60°C (-76°F) during the winter months. The average temperature on the summit ranges between -36°C (-32°F) and -27°C (-17°F) throughout the year.
The side of a mountain that experiences the rain shadow effect is the leeward side, or the side opposite to the direction of the prevailing winds. As moist air is forced to rise over the windward side of the mountain, it cools and releases moisture in the form of rain or snow. By the time the air descends on the leeward side, it has lost much of its moisture, creating a drier microclimate known as the rain shadow.
