Roter Kamm crater
Roter Kamm (German: Red Ridge) is a meteorite crater, located within the Namibian section of the Namib Desert approximately 80 kilometres (50 mi) north of Oranjemund in the ǁKaras Region. It is 2.5 km in diameter and is 130 metres (430 ft) deep. The age is estimated to be between 4 and 5 million years placing it in the Pliocene.[1] The crater is exposed at the surface, but its original floor is covered by sand deposits at least 100 metres (330 ft) thick.
The meteorite hit a layer of precambrian granitic gneiss that is part of the Namaqua Metamorphic Complex, overlaid with some younger sedimentary rocks. No parts of the meteorite have been found, suggesting that it completely evaporated upon impact.[2] The meteor that hit it was approximately the size of an SUV.[3]
