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,
Tunnunik impact crater diameter struck the Earth. The desert-like landscape of impact craters like Tunnunik can be useful in understanding the geology of other rocky planets such as Mars. It is Canada's 30th known meteorite impact feature. Not to be confused with the unconfirmed Victoria Island structure in California, United States. Tunnunik impact crater The Tunnunik impact crater, formerly known as the "Prince Albert Impact Crater", is a recently confirmed meteorite impact crater. It is located on Prince Albert Peninsula in the northwestern part of Victoria Island in Canada's Northwest Territories. The wide crater was discovered in 2010 by Brian Pratt, professor of
