Joshua Tree’s jumbled geology captivates every visitor who sets foot in the park. Surreal rock formations rise out of the ground like petrified balloons and spread over the landscape like dripped wax.
You don’t need to know a thing about geology to enjoy the scenery here. But take the time to learn about the forces that sculpted the rocks, and you’ll look upon the park with a fresh set of eyes. The seemingly fixed landscape will roll into motion. Mountains will wash away like piles of sand. Ice ages will come and go like snowstorms, and 70-ton boulders will dissolve like sugar cubes as you stare across the park.
