Rutherford Crater is an impact crater in the Oxia Palus quadrangle on Mars at 19.2° N and 10.7° W. and is 110.5 km in diameter. Light-toned rocks on Mars have been associated with hydrated minerals like sulfates. The Mars Rover Opportunity examined such layers close-up with several instruments. (wikipedia entry)
