Geologist Marking Chalk Bedding Planes Night South Sudan

Cold moonlight washes the rugged rock face in shades of slate and charcoal. A geologist stands against the steep outcrop, their white chalk line cutting sharply against the dark, wet stone. The rock layers reveal distinct horizontal bedding planes, slick with recent rain from the wet season. Heavy clouds hang low above, diffusing the pale lunar glow into a soft, even illumination. The figure wears practical field gear, slightly damp at the cuffs, holding a small white stick against the stone. Beside them, a deflated weather balloon rests on the muddy ground, its fabric crumpled in the shadows. The chalk mark ends abruptly at a small, jagged crack in the rock.
