Vinogradov is an old, 224-kilometer diameter, heavily degraded impact crater in southern Margaritifer Terra.
The southeastern floor of Vinogradov is covered with several mysterious light-toned, sub-meter scale "blobs" that lack obvious layering. In some places the light-toned material appears to have filled pre-existing craters giving them a circular appearance.
The light-toned material has a northwest-southeast orientation and tends to be associated with a smooth, darker-toned deposit. This material may be related to ejecta from a nearby crater, eroded from the rim of Vinogradov or emplaced by some other process.
This is a stereo pair with ESP_037519_1590.
