Irregular Graben Features

The graben in this image contains an unusually tall cone with very even sides, and the surrounding terrain is darker in the direction of prevailing wind. This observation could bring out some of the detail around this unusual feature and show possible changes that have occurred over the last ten Earth years in case this area is thermally active.
