Copper Alluvial Fan Near Nouakchott Before Dusk

Copper-toned light spills across a vast alluvial fan spreading from a deep canyon mouth near Nouakchott. The sedimentary slopes display layered textures of ochre, rust, and pale sand, shifting in color as the sun dips below the horizon. A shallow pool of water at the fan's base acts as a mirror, reflecting the striated rock faces and the clear sky above. The landscape stretches wide and flat, showing the scale of the geological formation against the encroaching twilight. Shadows lengthen gently across the dry riverbed, while the water surface remains glass-smooth, doubling the visual weight of the canyon walls. at the edge is the sharp edge where the dry sand meets the dark, still reflection of the canyon rim.
