Opportunity Traverse Map for Cape York: A region known as Cape York on the western rim of Endeavour Crater, where NASAs Mars Exploration Rover Opportunity worked for 20 months, is highlighted in these images. The inset at upper left is a portion of a false-color image taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASAs Mars Reconnaissance Orbiter. The black outline shows the Matijevic Hill region, enlarged in the central image. Initial traverses accomplished by Opportunity to evaluate the geologic setting of the region are noted. The Opportunity team was interested in this region because the Compact Reconnaissance Spectrometer for Mars (CRISM) on NASAs Mars Reconnaissance Orbiter showed a specific type of clay mineral called a ferric smectite. This type of clay mineral originally formed in groundwater along fractures in which the water was only mildly acidic. The lower left inset shows a portion of CRISM data centered on Cape York. The red region delineates where CRISM spectra show features diagnostic of the smectite clay mineral.
