| Joshua Tree encompasses three of California’s ecoregions. Its geology
shows the effects of plate tectonics, volcanism, mountain-building, and
stark erosion. With elevations ranging from 900 feet to over 5000 feet above
sea level, the park is home to a diversity of biological communities found
nowhere else in such proximity. Sand dunes, dry lakes, flat valleys, extraordinarily
rugged mountains, granitic monoliths, and oases are all found within its
nearly 800,000 acres. Each feature makes its contribution to the natural
tapestry of the southwest. |
