Joshua Tree National Park - Geologists believe the modern landscape of the park was born more than 100 million years ago. Molten liquid, heated by the continuous movement of Earth’s crust, oozed upward and cooled into granite while still below the surface.
After the arrival of the arid climate of recent times, flash floods began washing away the protective ground surface. As they were exposed, the huge eroded granite boulders settled one on top of another, creating the impressive rock piles seen today.
This is a bold set of outcroppings seen just before the sun slips below the horizon on the road leading to the North Entrance Station.
