  Title: STS-48 ESC Earth observation of southwestern corner of the Great Salt Lake
  Description:
  STS-48 Earth observation of the southwestern corner of the Great Salt Lake, 
  308 nautical miles below Discovery, Orbiter Vehicle (OV) 103, was provided
  by  the electronic still camera (ESC).  While the image is mostly covered
  with a  thin veil of cirrus clouds, many of the surface features can be
  recognized.   The causeway linking the northern tip of the peninsula to the
  southwest shore  of the lake is clearly visible as is the interstate
  highway.  Considerable  topographic detail is visible in the snow covered
  peaks to the south of the  lake.  The commercial salt pans between the
  peninsula and the interstate show  high contrast with the brightness
  dependent on the concentration of the  brackish water in the pan.  Recent
  heavy rainfall has caused considerable  runoff into the lake but the
  flooding hazard of a few years past no longer  exists due to a pumping
  system that now transfers excess water to the  Bonneville Salt Flats. The
  ESC image was stored on a removable hard disk or  small optical disk and
  was converted to a format suitable for downlink  transmission. The ESC
  documentation was part of Development Test Objective  (DTO) 648, Electronic
  Still Photography.
