Salt caves, rugged canyons, and dry lake beds also dot the valley floor, making it a popular area for hiking, sightseeing, and geological study.
Climate and Environmental Conditions
The Atacama Desert, where the Valley of the Moon is situated, is considered one of the driest places on Earth. Rainfall is extremely rare, with annual precipitation often less than 15 millimeters (about 0.6 inches).
Daytime temperatures can exceed 30°C (86°F), but nights become cold due to the high desert altitude and clear skies. Humidity remains persistently low, and there is almost no permanent surface water.
This arid, hostile climate means little to no plant or animal life is found within the valley. The intense sunlight and clear atmosphere create vivid contrasts in color and shadow, enhancing the otherworldly, moon-like appearance of the landscape.
Unique Martian Landscape Features
The Valley of the Moon in Chile's Atacama Desert is known for scenery that closely resembles the geological features seen on Mars. Its dry climate, unusual surface textures, and dramatic landforms attract scientists and visitors seeking a terrestrial analog of the Martian environment.
Salt Flats and Rock Formations
Large salt flats cover expanses of the valley floor, forming bright, reflective patches that stand out against the arid landscape. These salt deposits are the result of ancient evaporated lakes, leaving behind mineral crusts that crunch underfoot.
Among the most distinctive features are the Tres Marías formations, three elongated rocks that rise starkly from the salt crust. Their shapes, sculpted by millennia of wind erosion, create a landscape that feels both alien and ancient.
Rock outcrops show layers of sediment and minerals, often striped with white salt. This geology provides valuable insight into both the history of the Atacama and the kind of mineral deposits found in Martian valleys.
Dunes and Sand Structures
Wind-driven dunes are a dominant feature in the Valley of the Moon. These dunes, formed from fine-grained sand and silt, shift and reshape with the prevailing winds, creating ever-changing patterns and ridges.
Some dune crests reach impressive heights and are often traversed for panoramic views of the valley and the distant Licancabur volcano. The shapes and ripples in the sand mimic dune fields observed by Mars rovers in the planet’s equatorial regions.
Sand structures are interspersed with rocky debris and gypsum crystals, offering more texture and contrast to the landscape. This mix of sand and stone is crucial for researchers studying physical weathering in Earth’s oldest deserts.
Caves and Craters
Shallow caves and eroded hollows pockmark the valley’s surface, showing evidence of chemical weathering and wind-driven erosion. These voids are typically found in cliffs or rock walls that contain higher concentrations of salt and gypsum.
Craters in the Valley of the Moon are not created by meteorites but formed through subsidence and erosional processes unique to hyper-arid deserts. Some depressions are ringed with calcium sulfate, giving them a pale, lunar-like appearance.
The caves and craters provide habitats for extremophiles—organisms adapted to survive intense dryness and saltiness. Their study helps astrobiologists theorize about the potential for life in similar Martian environments, especially in regions like Mars Valley or near volcanic features such as Licancabur.
