Grindavik is an impact crater in the Oxia Palus quadrangle of Mars, located at 25.39° North and 39.07° West. It is 12 km (7.5 mi) in diameter and was named after Grindavík, a town in Iceland.[1] Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km or 6.2 mi in diameter) they usually have a central peak.[2] The peak is caused by a rebound of the crater floor following the impact.[3]
