Sediment Tubes on Bench Under Corrugated Roof Dawn Tunisia

Deep shadows cloak a wooden bench holding rows of clear sediment tubes beneath a gray corrugated metal roof. Thin rainwater beads on the tubes and drips onto a mud-splashed notebook resting at the edge. Early autumn light breaks through low-hanging clouds, creating a sharp silver rim along the roof's ridges and the curved dome of an observatory in the background. The wet wood grain of the bench contrasts with the smooth plastic of the containers. one drop of water hangs from the notebook's corner, ready to fall onto the damp surface below.
