Sandstone Arch Over Floodplain Near Nouakchott

Bright midday sun illuminates a weathered sandstone arch rising from a flat, wet floodplain near Nouakchott. The stone surface shows deep vertical erosion lines and a warm ochre tone that contrasts with the pale, shimmering heat haze hovering just above the ground. Beyond the arch, a distant mesa stands as a solid, flat-topped block against a washed-out sky. The floodplain stretches out in a mosaic of damp, dark earth and scattered shallow puddles that reflect the harsh light. From the high vantage point, the arch acts as a natural window, framing the arid horizon while the surrounding terrain appears smooth and slightly rippled from recent rain. The shadow beneath the arch is sharp and confined, showing the stone's thickness against the vast, empty space.
