Bentonite Hills – Mars

The Bentonite Hills are composed of volcanic ash deposits from the Jurassic period, which have transformed over millions of years into a unique popcorn-textured clay. When these hills are dry, they appear as a muted, earthy grey; however, after a rain or during the soft light of dawn and dusk, they explode into vibrant bands of purple, maroon, ochre, and blue. The result is a topographic masterpiece that feels entirely disconnected from the traditional red rock scenery of Southern Utah.

Because the bentonite clay is highly absorbent, it swells and shrinks with moisture, creating a delicate, "popcorn" crust that is incredibly fragile. This is a landscape where the visual reward is matched by the environmental responsibility; visitors are encouraged to stick to the washes and existing paths to avoid crushing the very textures that make this "Martian" terrain so special. It is a place where geology becomes art, and every ridgeline offers a new, otherworldly perspective.
