Description and Formation

  1. (1)

    Crater-associated frost streak (Fig. 1): Bright streaks composed of seasonal wind transported accumulations CO2 frost/snow, present in the lee of craters in the polar regions of Mars. They appear after the annual cap has formed, and they are surrounded by a less bright cover of the annual cap. The albedo difference is due to a more complete frost cover of the ground within the streaks than in the surrounded cap (Thomas et al. 1979, 1981).

     
  2. (2)
    Polar frost streaks (Figs. 2 and 3): They are found on the polar layered terrain. Polar frost streaks form by off-pole katabatic drainage winds generated by the broadly domal topography of the layered deposits (Howard 2000). They form when wind velocities are at a maximum, during southern spring and summer. When the...
