Summary
DescriptionMissoula spirit.jpg
English: This mosaic was assembled from images taken by the panoramic camera on the Mars Exploration Rover Spirit at a region dubbed "site 31". Spirit is looking at "Missoula Crater". From orbit, the features within the crater appeared to be ejecta from the younger "Bonneville Crater", but Spirit's closer look revealed wind-blown drift deposits, not ejecta, within Missoula Crater.
