This scene, 650 kilometers to the east of Olympus Mons, shows a circular feature about 3 kilometers in diameter with raised rims surrounded and infilled by lavas.

A lava channel extends from the feature and continues 60 kilometers to the northeast, growing deeper along its path. The circular formation is likely an eroded impact crater whose walls have been breached by the lava as it surrounded the rim and then infilled the crater. Alternatively, it could represent the location of a volcanic vent that sourced some of the lavas that formed the channel.
