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,
Toms Canyon impact crater USGS scientists, show that the crater was formed by an object or objects which struck from the southwest at a glancing angle and formed a long, oval crater. Since impact, sediment filled part of the crater, giving it its present triangular shape. Toms Canyon impact crater The Toms Canyon impact crater is a probable impact crater where one or more asteroids struck the Atlantic continental shelf, about east of Atlantic City, New Jersey. The submarine canyon is the drowned glacial-age mouth of Toms River. The crater dates to the late Eocene geological time period (about 35 million years ago), and
