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,
Haughton impact crater Haughton impact crater Haughton impact crater is located on Devon Island, Nunavut in far northern Canada. It is about in diameter and formed about 39 million years ago during the late Eocene. The impacting object is estimated to have been approximately in diameter. Devon Island itself is composed of Paleozoic shale and siltstone overlying gneissic bedrock. When the crater formed, the shale and siltstone were peeled back to expose the basement; material from as deep as has been identified. At 75° north latitude, it is one of the highest-latitude impact craters known. The temperature is below the freezing point of
