Strange Flow: Landslide, Impact Melt or Lava?
ESP_039117_1745  Science Theme: Impact Processes
This observation shows the full-width of a HiRISE image and its enhanced color strip, which only covers approximately 20 percent of the picture.

The image is approximately 6 by 6 kilometers and is located east of Noctis Labyrinthus, in a portion the large canyon system Valles Marineris. Visible in this image is a close-up of extensive deposits (some of which has a bluish color) that originated outside of the valley. These deposits appear to have flowed down towards low-lying areas and then bank up against higher topographic features.

Scientists are trying to determine if these deposits represent materials deposited by a massive landslide, an impact crater or a nearby volcanic event.
