The Mast Camera (Mastcam) on NASA's Curiosity Mars rover captured this mosaic as it explored the "clay-bearing unit" on Feb. 3, 2019 (Sol 2309). This landscape includes the rocky landmark nicknamed "Knockfarril Hill" (center right) and the edge of Vera Rubin Ridge, which runs along the top of the scene.

Made of many individual images, this mosaic includes a variety of geological features, such as several kinds of bedrock and sand. The clay-bearing unit has been an important scientific destination since before Curiosity launched. NASA's Mars Reconnaissance Orbiter (MRO) spied a strong clay "signal" in this region, indicating that water may have played a role in its formation. On its long trek since landing in 2012, Curiosity has discovered many examples of mudstones containing clay minerals.

The scene is presented with a color adjustment that approximates white balancing to resemble how the rocks and sand would appear under daytime lighting conditions on Earth.

Malin Space Science Systems in San Diego built and operates Mastcam. A division of Caltech, the Jet Propulsion Laboratory in Pasadena, California, manages the Mars Science Laboratory Project for NASA's Science Mission Directorate in Washington and built the project's Curiosity rover.
