  Title: STS-55 Earth observation of Altiplano ash/dust plume in Argentina
  Description:
  STS-55 Earth observation taken from Columbia, Orbiter Vehicle (OV) 102,
  shows  several plumes of blowing material over northern Argentina.  All
  plumes  originate downwind of the recent volcanic eruption of Lascar
  Volcano (just  over the border in northern Chile). It seems most likely,
  therefore, that the  blown material is dust-sized particles of ash that was
  deposited on the high  Andean plateau by Lascar during the eruption of
  04-20-93.  The large, dense,  V-shaped plume in this frame is about 40
  kilometers long.  It is blowing  eastwards from a point about 100 km
  southeast of Lascar.  On 05-10-93, images  from the AVHRR sensor on the
  environmental satellite NOAA-11 showed the dust  from these parts of
  Altiplano reaching the lowlands hundreds of kilometers to  the east.  This
  photo was recorded on 05-04-93 at 19 hours 10 minutes 38  seconds GMT.
