</p><p>An image taken at the "Hidden Valley" site, en-route to Mount Sharp, by NASA's Curiosity rover. A variety of mudstone strata in the area indicate a lakebed deposit, with river- and stream-related deposits nearby. Decoding the history of how these sedimentary rocks were formed, and during what period of time, was a key component in the confirming of the role of water and sedimentation in the formation of the floor of Gale Crater and Mount Sharp.
</p><p>This image was taken by the Mast Camera (Mastcam) on Curiosity on the 703rd Martian day, or sol, of the mission.
