Tikhonravov (crater)

Tikhonravov is a large, eroded crater in the Arabia quadrangle of Mars. It is 344 km in diameter and was named after Mikhail Tikhonravov, a Russian rocket scientist. Tikhonravov is believed to have once held a giant lake that drained into the 4,500 km Naktong-Scamander-Mamers lake-chain system. An inflow and outflow channel has been identified. Many craters once contained lakes.

Pedestal craters
Some craters in Tikhonravov are classified as pedestal craters. A pedestal crater is a crater with its ejecta sitting above the surrounding terrain. They form when an impact crater ejects material which forms an erosion resistant layer, thus causing the immediate area to erode more slowly than the rest of the region. The result is that both the crater and its ejecta blanket stand above the surroundings.
