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,
Cloud Creek crater skirt, and four through the outer rim structure. Cloud Creek crater Cloud Creek crater is an impact crater in Wyoming, United States. The crater is located in Natrona County, about 48 miles northwest of Casper, near the center of a geological feature known as the Casper Arch. The Cloud Creek structure is circular with a current diameter of about 7 km, and it is buried beneath about 1200 m of Mesozoic rocks. The age of the structure is estimated to be 190 ± 20 million years, which means that it formed as the result of an impact during the early
