Image Caption:
El Chichon sits by itself in eastern Mexico. The summit is still
deforested and surrounding rivers remain choked with ask after
the 1982 eruption. Recovery from major eruptions may take several
decades. The photograph was taken on 28 April 1990 from an alti-
tude of 331 n.mi. (613 km) using a Hasselblad camera equipped
with a 250 mm lens and color IR film. (Photo ID: S31-91-068).
