this crater formation has been significantly disintegrated by smaller impacts around the outer rim, leaving a wall that is deeply notched and incised. there is a gap in the western rim through which the interior has been flooded and resurfaced by layers of basaltic lava. thus all that remains of the original crater is an irregular, crescent-shaped formation along the southern edge of the lacus somniorum. the southern rim is attached to the rough terrain to the south of the mare, and the irregular satellite crater g. bond g is attached to the southeast rim.
