Pretty dunes in Gale Crater
Pretty dunes in Gale Crater These dunes and ripples share a valley with an ancient, infilled channel on the mound of sediment in Gale Crater, near the end of the proposed MSL traverse. They are especially striking because they are made of dark volcanic sand, mixed with light-toned sand from the sediments filling the channel.Image: NASA / JPL-Caltech / U. Arizona
