The road to Joshua Tree National Park. 

The high desert, very dry throughout the year

in addition, it can be very cold in the winter time

It may even snow in some places.

That's why the vegetation is very different from 

other kind of desert.

Joshua Tree, the plant that can only be found around

this kind of high desert (Mojave Desert) is the unique 

feature of the area and thus the name for the National Park.
