Rippled sand dunes sing an eerie chorus. Cactus flowers bloom after a spring rain,
jewels against buff-colored earth. Saltbush borders a dry lakebed, and countless
Joshua tree limbs reach toward the sky as if in prayer. Mojave is all of these scenes
and more -- a bounty for the senses.
Summer temperatures often exceed 100 F; yearly rainfall ranges four to 14 inches.
Mountains, cinder cones, lava beds, sand dunes and dry lakes attest to the geological
forces at work through the ages.
Many variables -- elevation, moisture, soil composition, exposure to the sun and shelter
from the wind create habitats for plants and animals. Habitats of course, do not have
hard boundaries and often overlap. Different habitats may be encountered within a short
distance of each other.
