Image Caption:
Erg El Ahmar T6

Two views looking southeastward show the small dune field of the
Erg El Ahmar (located west center of the Erg Chech Site). An ar-
row on the 100 mm lens view shows the approximate location of the
250 mm view. Numerous small escarpments, playas, and wadis can
be seen on the 100 mm view. Formative winds blow from the bottom
left in both views. (S30-87-035, 036, S34-85-102)
