The Mojave Desert is special because it has a little bit of everything. People refer to the Mojave Desert as a "high desert" because it has an elevation of 2,000 to 5,000 feet. It changes from a cold desert in the northern section and a hot desert in the southern section. The Mojave Desert covers 25,000 square miles. There are some fascinating features to be found in this desert, especially the Kelso Dunes. The Kelso Dunes are the largest of the Mojave dune fields, reaching 500 to 600 feet in height. When you run down these dunes you can hear an unusual "barking" sound. It is not entirely understood yet but some people believe that grains of quartz and feldspar rubbing against each other cause it.
The key to the Sonoran Desert's climate is the amount of rainfall which falls. More rain falls on the Sonoran Desert than any other desert. When it does get rain, the desert is damp, and the air is cool. When it has no rain the desert is really dry and really hot. When the desert is windy, the sand gets picked up and tossed around which creates a sand storm or if the wind is blowing in a certain kind of way, it creates a whirlwind or dust devil. These mini-tornados move across the desert floor and they most often occur in hot weather. The desert valley is hot while up in the mountains it is cool and some mountains are even snow covered.
Which desert would you choose?
