This Curiosity image shows a rock outcrop called Link. Rounded gravel fragments up to a couple inches in size are in a matrix of white material. Many gravel-sized rocks have eroded out of the outcrop onto the surface, particularly in the left portion of the frame. The outcrop characteristics are consistent with a sedimentary conglomerate, or a rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together (NASA / JPL-Caltech / MSSS)

$The image shows the interconnected craters Sigli and Shambe, believed to have formed when a large meteorite fragmented in to two pieces just before impact. Extensive fracturing can be seen within the craters. Above the craters, west, creek-like flow channels can be seen leading in to the wider impact basin region to the right, north (ESA / DLR / FU Berlin / G. Neukum)$
