Layered deposits visible in Ryder crater, photographed by LROC

This circular-rimmed crater lies along the eastern rim of a larger formation that is most likely the remains of an old, worn impact. Less than a crater diameter to the west of Ryder is the 24-km-diameter satellite crater Pauli E. Ryder is an oblique impact, and a coherent, layered piece of the lunar crust lies on its side on the eastern side of the crater.^[2]
