Deposits of impact glass have been preserved in Martian craters, including Alga Crater, shown here. In color coding based on analysis of data from the CRISM instrument on NASA’s Mars Reconnaissance Orbiter, green indicates the presence of glass; blues are pyroxene; reds are olivine. This view shows Alga Crater’s central peak, which is about 3 miles (5 km) wide within the 12-mile (19-km) diameter of this southern-hemisphere crater. The information from CRISM is shown over a terrain model and image based on observations by the High Resolution Imaging Science Experiment (HiRISE) camera. The vertical dimension is exaggerated by a factor of two. Image credit: NASA / JPL-Caltech / JHUAPL / University of Arizona.

The Reiner Gamma formation is a well known lunar swirl region, due to its nearside location. Swirls are described by curving, diffuse bright patterns, which are interspersed with darker lanes. These anomalous albedo patterns are associated with local magnetic anomalies of varying intensities; swirl complexes are often extensive and may stretch across thousands of kilometers, well beyond localized magnetic anomalies.
