This photograph is quite interesting from climatological and geophysical point of view.

The upper mountain range lacks vegetation due to cold weather conditions. The lower plains in front of the mountain lack vegetation due to dry conditions. The result is a small belt of forest vegetation, where precipitation and temperature allow good growing conditions. Right at the end of the plains there is a huge fault that has been created by a strong earthquake. The picture shows Lost River Range near Leslie, Idaho, USA.

Rough and high mountains usually rise into zones of permenant underground freezing. This photograph from Iceland shows flowing of mountain slopes due to permafrost conditions.
