Description: The Shoemaker impact site is approximately 30 kilometres in diameter and clearly defined by concentric ring structures formed in sedimentary rocks (brown to dark brown, image centre). Several saline and ephemeral lakes—Nabberu, Teague, Shoemaker, and numerous smaller ponds—occupy the land surface between the ring structures. Differences in colour result from both water depth and from suspended sediments, with some bright salt crusts visible around the edges of smaller ponds (image centre).
