arid region

South of this arid region, strewn with great lava stones, are the Rendile uplands, affording pasturage for thousands of camels.

In this arid region much of the vegetation is set with thorns, and some of the animals are made to match the vegetation.

The powers of erosion are far slower than those of corrasion, especially in an arid region, because they are intermittent.

The same has been done in the arid region of the United States.

A glance at the map will show that the Park is in the midst of a vast arid region extending far into the surrounding states.
