Cerro de los Siete Colores, Mineral-colored mountain formation in Purmamarca, Argentina

Cerro de los Siete Colores is a mountain slope rising directly behind Purmamarca in Jujuy Province. Its upper part is a broad mass of rust-red and orange rock; below it, bands of pale pink, white, grey and purple run diagonally across the face, and grey-green mountains stand behind the crest. The layers are marine, lake and river sediments lifted by tectonic movement.

The formation originated from marine sediments that accumulated when the region was covered by ancient oceans millions of years ago. Tectonic uplift later raised these layers and shaped the mountain into its present form.

The hill gives its name to Purmamarca, which in Quechua means "town of the lion" or refers to the arid land, and it appears on the town's imagery. The Santa Rosa de Purmamarca football club plays at the field at its base, and the 2024 Fortnite recreation by the Foreign Ministry carried the hill to a global audience.

The mountain is accessible by foot from Purmamarca village with several paths leading to different viewpoints. Early morning light provides the clearest visibility of the colored layers and makes photography easiest.

At the foot of the slope lies a football pitch, home ground of Santa Rosa de Purmamarca in the Quebradeña Football League. In 2024 Argentina's Ministry of Foreign Affairs worked with a video game studio to recreate the hill inside Fortnite.
