                                          November 4, 1997
                                          Twin Peaks (b/w)
                         

The Twin Peaks are modest-size hills to the southwest of the Mars Pathfinder landing 
site.  They were discovered on the first panoramas taken by the IMP camera on the 4th 
of July, 1997, and subsequently identified in Viking Orbiter images taken over 20 
years ago.  The peaks are approximately 30-35 meters (-100 feet) tall.  North Twin is 
approximately 860 meters (2800 feet) from the lander, and South Twin is about a 
kilometer away (3300 feet).  The scene includes bouldery ridges and swales or 
"hummocks" of flood debris that range from a few tens of meters away from the lander 
to the distance of the South Twin Peak.  The large rock at the right edge of the 
scene is nicknamed "Hippo".  This rock is about a meter (3 feet) across and 25 meters 
(80 feet) distant.

Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with 
highly focused science goals. The Jet Propulsion Laboratory, Pasadena, CA, developed 
and manages the 
Mars Pathfinder mission for NASA's Office of Space Science, Washington, D.C.  JPL is 
a division of the California Institute of Technology (Caltech). The IMP was developed 
by the University of Arizona Lunar and Planetary Laboratory under contract to JPL.  
Peter Smith is the Principal Investigator.
