This digital elevation map shows the topography of the "Columbia Hills," just in front of the Mars Exploration Rover Spirit's current position. Rover planners have plotted the safest route for Spirit to climb to the front hill, called "West Spur." The black line in the middle of the image represents the rover's traverse path, which starts at "Hank's Hollow" and ends at the top of "West Spur." Scientists are sending Spirit up the hill to investigate the interesting rock outcrops visible in images taken by the rover. Data from the Mars Orbital Camera on the orbiting Mars Global Surveyor were used to create this 3-D map.
