This is an infrared image of Ius Chasma taken at night. Bright surfaces are warmer than dark surfaces; the floor of the chasma is warmer than the plains at the top of the frame. Nighttime infrared images are extremely helpful in identifying bedrock outcrops, which stay warmer than dust covered surfaces. The landslide is also easy to identify in this image.
