- Alpine Desert -
Zone 5: Alpine Desert
Altitude: roughly 13,200 to 16,500 feet
This is a harsh, dry, windy region, consisting mostly of bare rock and ice. The temperature of the
area ranges from below freezing at night to over 100°F during the day. The air is very thin, and
radiation from the sun is intense. It rains less than 10 inches per year, and the zone's thin soils retain little of what does materialize so there are very few plants, mostly lichens and small mosses.
