Different biomes

One of the few places where you can drive from Mexico to Canada in about a half hour is Mount Lemmon near Tucson, at least you can pass through the biomes on your way up. As you make the vertical climb, you move from the Sonora Desert environment, through mixed woodland and ponderosa pine and finally get to a mixed pine-fir forest near the top. On the first picture you can see the various biomes lined up
The temperature at the bottom was a comfortable 65 degrees. At the top is was 37 degrees. Chrissy and I rented a convertible so that we could see and feel all the differences on the way and and we kept the top down, admittedly with the heater on, all the way up.
