Columbia Hills' elevation map from MGS

This elevation map shows the region of the Columbia Hills where Rover Spirit has been working since mid-2004. Areas colored blue are lower in elevation while areas colored yellow are higher.
The map imagery is from the MOC on NASA's MGS orbiter.
More than 15 months after landing on Mars, the Spirit rover is still going strong, having traveled a total of 4.276 mt as of Sol 450 (April 8, 2005). This elevation map shows the traverse followed by Spirit since arriving at the "Columbia Hills" in June, 2004.
The blue area at the foot of the Columbia Hills is approximately 20 mt higher in elevation than the site where Spirit landed in Gusev Crater. The highest peak is on the order of 80 mt higher still".
