Image Caption:
Lake Chad, Late 1988 T15

In late summer, 1988, parts of the Sahel had received heavy
rains. However, the shorelines of Lake Chad continued to recede,
as can be seen in this oblique view of the lake taken on STS-26.
Note the smoke palls (arrows) around the old shoreline. (S26-

STS026-46-052 - This photograph of the Lake Chad Basin and Sahel
Rgreen lineS was taken October 3, 1988, looking east from 12.1!
N, 8.7! E. The altitude of the Discovery at this time was 168
miles. Local duststorms are blowing west across the Grand Erg de
Bilma in northern Chad to the left. Lake Chad itself has shrunk
to a small remnant (~5%) of the large lake of 1966, marked by
dark-toned vegetation and strandlines. Range fires are burning
to the southeast of Lake Chad and along the southwestern shore of
the 1966 lake edge. The small white and brown dots are villages,
surrounded by barren areas created by firewood foraging.
