Tags: Crater.
McLaughlin Crater is an old crater in the Oxia Palus quadrangle of Mars located at 21.9°N 337.63°E / 21.9; 337.63. It is 90.92 km (56.50 mi) in diameter and 2.2 km (1.4 mi) deep. The crater was named after Dean B. McLaughlin an American astronomer (1901-1965). The Mars Reconnaissance Orbiter has found evidence that the water came from beneath the surface between 3.7 billion and 4 billion years ago and remained long enough to make carbonate-related clay minerals found in layers.
