Clark Crater, as seen by CTX camera (on Mars Reconnaissance Orbiter)
Clark Crater is a crater in the Phaethontis quadrangle of Mars, located at 55.6°S latitude and 133.4°W longitude and is in the southeastern part of Terra Sirenum. It is 98.0 km in diameter and was named after Alvan Clark, and the name was approved in 1973.
Clark is run by one of the faults of Icaria Fossae which runs from southwest to northeast, with one crossing near the center of the crater. Other nearby craters include Hussey to the northeast, Dokuchaev to the southeast and Nansen further northwest.
Dunes are visible on the floor of the crater, and dust devil tracks are in the area. The thin, dark streaks are dust devil tracks.
