Inland delta of the Niger River. (A) In October 1996 (NASA photograph NM22-736-055) the dark green vegetation is luch when water from the summer rains pass through the region. Although vegetation cover lasts only a few months, it provides a strong visual contrast with the surrounding desert countryside. (B) By April 1997, the wetlands have dried up, and the inland delta is a uniform tan color (NASA photograph NM23-730-271). The white box outlines the area covered by view (A).
