A mosaic of Mastcam images captured by NASA's Curiosity rover on November 10th, 2016 (Sol 1,516), showing the lower slopes of "Mount Sharp". Variations in the rocks colour hint at the diversity of their composition. The purple tone of the foreground rocks has been seen in other rocks where hematite has been detected. Winds and windblown sand help to keep rocks relatively free of dust which would otherwise obscure their colour differentiation. These images have been white balanced, so the scene appears as it would under typical Earth daylight conditions
