On the western slopes of the Shotori Mountain Range, near the beautiful village of Geshn, the Geshn “Martian” Hills form a spectacular and wonderful landscape. Just 25 km from Tabas, this geosite takes visitors into a landscape that feels like another world. These hills are composed of marl—a soft sedimentary rock made of clay and limestone—with a delicate bluish color that recalls the ancient seas that once covered this region. The sediments were deposited in the depths of Jurassic seas approximately 165 to 161 million years ago.

Thousands of years of wind and rain erosion have transformed these hills into a unique landscape known by geologists as badlands, or “a land of a thousand valleys.” A complex network of valleys and gullies creates an endless panorama, as if the Earth itself carries thousands of ancient scars. The Geshn “Martian” Hills are a living testimony to the long and fascinating history of our planet. Visitors experience not only soil and rocks, but also a deeper connection with geological time, evoking the silent Jurassic seas that once covered this land. Here, beauty and scientific knowledge shine together, creating an unforgettable experience for every visitor.
