　　　　In the eastern basin area and the lower western valleys that are sheltered from cold polar air masses by the surrounding mountains, there are 350 frost-free days in the east, and the growing season lasts nearly all year round. In the west, the sheltering effect of the mountains is evident from the contrast between the perennially snow-capped peaks and the mild weather prevailing in the valleys beneath them.
