The two hills in the distance, approximately one to two kilometers away, have been dubbed the 'Twin Peaks.' The image was taken by NASA's Imager for Mars Pathfinder (IMP) after its deployment on July 7, 1997.

The two hills in the distance, approximately one to two kilometers away, have been dubbed the "Twin Peaks" and are of great interest to Pathfinder scientists as objects of future study. The white areas on the left hill, called the "Ski Run" by scientists, may have been formed by hydrologic processes.

The image was taken by the Imager for Mars Pathfinder (IMP) after its deployment on Sol 3. Mars Pathfinder was developed and managed by the Jet Propulsion Laboratory (JPL) for the National Aeronautics and Space Administration. The IMP was developed by the University of Arizona Lunar and Planetary Laboratory under contract to JPL. Peter Smith is the Principal Investigator.

Photojournal note: Sojourner spent 83 days of a planned seven-day mission exploring the Martian terrain, acquiring images, and taking chemical, atmospheric and other measurements. The final data transmission received from Pathfinder was at 10:23 UTC on September 27, 1997. Although mission managers tried to restore full communications during the following five months, the successful mission was terminated on March 10, 1998.
