Title: View of eastern coast of Sicily area
A vertical view of the eastern coast of Sicily area is seen in this Skylab
3  Earth Resources Experiments Package S190-B (five-inch earth terrain
camera)  infrared  photograph taken from the Skylab space station in Earth
orbit.  Mount Etna, the highest volcano in Europe (10,958 feet), is still
active as  evidenced by the thin plume of smoke emaneting from its crest.
On the flanks  of Etna recent lava flows appear black in contrast to the
older flows and  volcanic debris that are red. Numerous small, circular
cinder cones on the  flanks represent sites of previous eruptions. Catania,
on the Mediterranean  coast south of Etna, is the largest of several cities
and villages which  appear as light-gray patches on the lower slopes of the
volcano. Plano de  Catania, south of the city of Catania, is outlined by
polygonal light and  dark agricultural tracts. Several lakes, the largest
of which is Lake  Pozzillo, show up as dark blue in the photograph. The
unusual colors in the  picture are due to the use of color infrared film in
which vegetation appears  red. This is very evident on the slopes of Etna,
in the Monti Nebrodi area at  upper left, and in the local areas in the
lower part of the picture.
