The floor of the Caloris basin consists of smooth, volcanic plains -- but these plains have been modified by subsequent impacts and tectonic deformation. This crater, which is located not only on the Caloris interior plains but half-covers its neighbor, has a sharp, well-preserved rim and internal terraces. The floor of the crater is some 900 m (~0.5 mi.) below the rim, making this crater's wall quite a cliff indeed.
