Baltisk is a crater in the Argyre quadrangle of Mars. It was named after a town in Russia in 1976.[1] Baltisk is located on the western edge of the Argyre impact basin.[2]

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 in diameter) they usually have a central peak.[3] The peak is caused by a rebound of the crater floor following the impact.[4]
