Islands in the Desert
Season 8 Episode 806 | 26m 46s | CC
In southern Arizona a handful of mountain ranges jut up from the desert, producing a dramatic change in landscapes and habitats. They are called Sky Islands because their higher slopes are wetter and harbor animals and plants not found below. We visit three of the best-known islands and talk with people who know them best.
