A male individual is depicted engaged in manual excavation within an open-air site in Ufueseni, Nigeria. The scene features prominent multi-layered earth cliffs; an upper reddish-brown stratum overlays a thick, lighter-colored stratum exhibiting vertical striations from prior digging. The individual, dressed in dark attire, holds a pickaxe-like tool and is actively breaking material from the lighter-colored cliff face. He stands on a sizable mound of excavated, light-colored, sandy material, streaked with reddish earth. A dark, cylindrical object rests on this mound. The background reveals a partially cloudy sky with both white and grey cumulus clouds. Sparse, tall grass is visible along the crest of the right-side cliff.
