A Mirror in the High Desert

The Laguna de Santa María is not a monument built by human hands, but a geological masterpiece sculpted by the harsh elements of the Argentine Puna. Located near the remote village of Tolar Grande, this high-altitude lagoon was formed millions of years ago as the Andes rose, trapping mineral-rich waters in a basin of volcanic soil and salt. Historically, it served as a vital watering hole for ancient caravans. Long before modern borders existed, the Lickanantay (Atacameño) people and later the Incas traversed these desolate plains, using the lagoon as a waypoint on the arduous trade routes connecting the Pacific coast to the fertile valleys of the east.

The Silent Guardians of the Water

While the lagoon appears tranquil, its history is marked by the silent passage of the Qhapaq Ñan, the Great Inca Road. Archeologists have found evidence that the surrounding peaks were considered huacas, or sacred sites. The most significant historical “event” here is the preservation of life itself; the lagoon is home to stromatolites—microbial reefs that are among the oldest life forms on Earth. These “living fossils” have survived in the lagoon’s extreme salinity and radiation for millennia, mirroring the conditions of the planet billions of years ago. The recent closure of the site is largely a protective measure to ensure these fragile organisms, which survived the extinction of the dinosaurs, do not succumb to the footprints of modern tourism.

The Legend of the Coquena

In the quiet reaches of Tolar Grande, storytellers speak of the Coquena, a mythical being who acts as the supreme protector of the high-altitude wildlife, particularly the vicuñas that frequent the shores of Laguna de Santa María. Described as a short man wearing a traditional poncho and a hat, he is said to be invisible to those with ill intentions. The Legend of the Coquena serves as a moral compass for the region:

• He rewards the humble shepherd who cares for his flock with gold or protection.
• He punishes the greedy hunter who kills more than he needs by leading them astray into the “white labyrinth” of the salt flats.
• Local guides often whisper a prayer to him before entering the basin, asking for safe passage through the thin, oxygen-poor air.

The Pachamama’s Breath

An enduring anecdote shared by the people of the Puna involves the “Viento Blanco” (White Wind). It is said that when the lagoon turns a specific shade of deep turquoise, the Pachamama (Mother Earth) is breathing. If a traveler is disrespectful—shouting or taking stones without permission—the Pachamama summons a sudden, blinding salt storm. This belief is why you will see apachetas (small stone cairns) near the access paths. Travelers add a stone to these mounds as a silent “license” to enter the goddess’s territory, a practice that continues even as the lagoon remains closed to the general public.

Signification culturelle aujourd'hui

For the residents of Tolar Grande, the Laguna de Santa María remains a symbol of the “Deep Argentina.” It represents a time when the landscape was a spiritual entity rather than a resource. Its current status as a restricted area has only added to its mystique, transforming it into a “forbidden sanctuary.” It stands as a reminder of the Puna’s fragility and the local commitment to preserving the sacred balance between the ancient past and the environmental future. To the locals, the lagoon is not “closed”; it is simply “resting,” reclaiming its silence from the modern world.
