    Let’s explore in images a stunning ridgeline in the Mercantour (Alpes-de-Haute-Provence). Through this photograph, part of a documentary series on the French Alps, a wild and unspoiled landscape unfolds, where light and terrain shape a timeless scene. A suspended moment, capturing the vision of Félix Briot (1845-1926), inspector of Water and Forests, and author of several studies and articles on mountain regions.

    The Forester and his tent

    Agate presents its current favorite.
    Here we are in 1877, in the Basses-Alpes, during the great mountain reforestation efforts. Through the lens of Eugène de Gayffier, a solitary tent stands watch over the freshly planted pine trees, a testament to the hard work of foresters striving to bring new life to these fragile lands.
