The THEMIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image. This image from NASA 2001 Mars Odyssey spacecraft shows part of the northern rim of Horowitz Crater. Horowitz Crater is located in Terra Cimmeria. Orbit Number: 58894 Latitude: -31.4618 Longitude: 140.816 Instrument: VIS Captured: 2015-03-25 01:00 https://photojournal.jpl.nasa.gov/catalog/PIA21548

The dark, narrow streaks flowing downhill on Mars at sites such as this portion of Horowitz Crater are inferred to be formed by seasonal flow of water on modern-day Mars in this image from NASA Mars Reconnaissance Orbiter.

This image comes from observations of Horowitz crater by the HiRISE camera onboard NASA Mars Reconnaissance Orbiter. The features that extend down the slope during warm seasons are called recurring slope lineae.
