Tête d'Auferrand

Tête d'Auferrand is a mountain summit in the Bornes massif located between two mountain passes. The peak forms a narrow, prominent ridge made of clay and limestone layers.

The summit formed during the Jurassic period when layers of clay and limestone were deposited. This geological history shaped the current form and composition of the peak.

Shepherds use the slopes as summer grazing land for their herds, a tradition that shapes the landscape seasonally. This pastoral practice remains an important part of life in the surrounding valleys.

Two hiking routes ascend from the southern mountain pass, one passing by a secondary peak and the other through a mountain valley. The climb time and difficulty vary depending on which route you choose.

The layers reveal an unusual arrangement with older limestone beneath and younger deposits above, a rare geological composition. This distinctive layering makes the site of particular interest to those who study rocks.
