Flow around Dromore Crater in Chryse Planitia. Flow was from the left and apparently ponded west of the mare ridge. It then cut gaps as it flowed over to low points in the ridge.
Similar relations occur in the channeled scablands of Washington State.
After crossing the ridge, the flow cut grooves in the Chryse Planitia floor as it flowed around Dromore, an older impact crater. The image is about 45 km across. North is to the upper right.
