Aerosols: Saharan dust over western tropical Atlantic Ocean on
June 16, 2001, approx. 12N 38W.

Aerosols: Saharan dust crosses the Atlas Mountains in Algeria
(top) and penetrates the Guadalquivir River valley in southern Spain
on June 19, 2001.

Aral Sea: Aral Sea, Central Asia. Waters of the Amu Darya and
Syr Darya (rivers) are almost completely diverted for agricultural
irrigation - little reaches the inland Aral Sea. By 1990 the surface
area of the Sea had decreased by about half and the salinity had
tripled since 1960. Our lengthy time series of photos from orbit
permits monitoring and quantification of changes in this disappearing
body of water.

Aral Sea: Aral Sea, dust storm on dry seafloor. Toxic
compounds ranging from agricultural chemicals to metallic and
biologic wastes were once beneath the Sea; now, however, the seabed
is largely dry and dust storms whip the toxins into the air and carry
them out over adjacent farmland.

Mountain Building: Southern Zagros Mts., southern Iran. The
broad, open folds of the Southern Zagros are characteristic of folded
mountains with rock salt, gypsum or similar materials at their cores.
Such salts behave plastically when mountain-building forces are
applied. This detailed photo shows several breached folds, from which
the salt cores have been eroded away. In the narrow up-arched fold
(anticline) at the right, individual rock layers can be seen to dip
away from the center of the structure and to be pervasively
fractured.

Mountain Building: Pyrenees, northeastern Spain/southern
France. The Pyrenees (highest point 3404 m), extend from the Bay of
Biscay (west) to the Gulf of Lyon (east). The range began forming
about 320 million years ago and was strongly uplifted again during
early stages of Eurasian-African plate collision. This fine photo
reveals details of folded and faulted strata of the southern
Pyrenees. Tin, tungsten, talc, fluorite, barium and gold have been
mined from the mountains, and petroleum is produced from the adjacent
Aquitaine sedimentary basin in France.

Mountain Building: Wind River Range, Wyoming. The broad,
SE-trending Wind River Mts. are part of the great Rocky Mountain
chain that stretches from northwestern Canada into northern Mexico.
That whole mountain system was created in response to the
long-lasting collision of the eastern Pacific and North American
tectonic plates. In this fine view, rock layers on the NE flank of
the range can be seen to dip away from the ridgecrest. Numerous
parallel joints and fractures control the locations of valleys and
stream courses along both flanks of the uplift.
