I love all the climate zones that are produced by mountains. I think the local wet and rain shadow areas around mountains are fascinating, but I also really appreciate the vertical gradient of climates from the base to the peaks.
I was just thinking about climate diversity and how seasons have a significantly different meaning for different climates.
1) Several thousand year old Bristlecone pine tree growing at high elevation and under harsh seasonal extremes.
2) Low elevation deciduous forest with mind seasons.
3) Tropical rainforest with little seasonal variations.
