Curiosity examined Canada Falls with the MAHLI camera on the end of the arm on sol 1634 (March 12, 2017). The rock may record a dry lakebed period within Gale crater. The view is a mosaic of three MAHLI observations.
Curiosity's Mastcam and ChemCam pointed at two locations on a wind-eroded outcrop on sol 1666 to examine whether the rock's color changes meant changes in composition. These fine-grained sedimentary rocks formed at a time when Gale crater held a lake.
On sol 1226 (January 17, 2016), Curiosity dumped sand that had been scooped from Namib dune on sol 1224. The left, "dump pile A", consists of sand that passed through the 150-micrometer sieve. The right, "dump pile B", is the portion that did not pass through that sieve.
