Arandas (crater) km in diameter) they usually have a central peak. The peak is caused by a rebound of the crater floor following the impact. Sometimes craters expose layers that were buried. Rocks from deep underground are tossed onto the surface. Hence, craters can show us what lies deep under the surface. Arandas (crater) Arandas Crater is a crater in the Mare Acidalium quadrangle of Mars, located 42.77° North and 15.17° West. It is 24.76 km in diameter and is named after the town of Arandas in Mexico. South is the scalloped terrain of Cydonia Labyrinthus and further south is Cydonia Colles,
Kearons (crater) Kearons (crater) Kearons is a small lunar impact crater that is located on the far side of the Moon, to the northwest of the Mare Orientale impact basin, in the outer skirt of ejecta that surrounds the Montes Cordillera range. It is a relatively isolated crater, possibly because any nearby features have been buried under the ejecta. Some distance to the south is the crater Lewis, and to the north-northeast lies Grachev. The rim of this crater forms a rounded polygon, with a sharp edge that has a small craterlet across the northwestern side. The inner wall and interior floor
