Ring-mold craters (RMCs) are rimless, concentric crater landforms with a circular outer moat and a variety of interior morphologies including central plateaus, pits, bowls, mounds, or multiple rings (Fig. 2), and they are named for their similarity to the cooking implement called ring mold (Kress and Head 2008). Ring-mold craters are best observed on images with a spatial resolution of 10 m/pixel or better (Pedersen and Head 2010).
Ring-mold craters are small-scale craters with diameters ranging from ca. 50 m to <1 km with observed average diameter between 100 and 200 m. Ring-mold craters are typically larger than the associated bowl-shaped craters, which also are found in lineated valley fill, lobate debris aprons, and concentric crater...
