Árbol de Piedra

The Árbol de Piedra is a rock formation in the Siloli Desert shaped by wind erosion over millions of years into an unusual tree-like silhouette. The structure features a narrow base that supports a wider upper section, creating a natural pillar-like monument.

This rock formation originated from volcanic activity that shaped the Andes during mountain building. Its present shape was carved by wind erosion over geological timescales at this extreme elevation.

Local Quechua communities view this formation as a sacred link between earth and sky within their Andean worldview. This spiritual connection appears in their stories and shapes how they relate to the high-altitude landscape.

Visitors reach this formation through guided tours from Uyuni in this remote desert region. Warm clothing is essential due to significant temperature swings and the thin air at this altitude.

Despite its unusual form where a narrow base supports a broader top, this formation has withstood millions of years of wind and erosion against all odds. The stability of this natural wonder makes it a sought-after photograph in the barren landscape.
