title: Mars: influence of topography on formation of temporary bright patches.
abstract: The Mountains of Mitchel and other temporary bright patches observed on the Martian disk may be carbon-dioxide condensations in depressions rather than a water-ice mixture on mountains as previously thought. This interpretation supports the hypothesis that the Martian deserts, that is, the light areas, are lower than their surroundings.
