An overhead photograph displays multiple white, rectangular metal grates covering a dark, grid-patterned drainage system in Lokoja, Nigeria. The grates are constructed from parallel horizontal slats, forming narrow rectangular openings. A prominent grate extends diagonally from the upper left to the lower center, partially overlapping a second grate visible in the lower right section of the frame. A third, smaller section of a similar grate is present in the upper right. Green vegetation, identified as small plants and weeds, protrudes through the apertures of both the white grates and the underlying dark structure, predominantly in the upper and central areas. The environment is an outdoor, brightly lit setting; no individuals are present, and no specific actions or interactions are depicted.
