Ridge at the center of Urvara Crater (closeup)

Ridge at the center of Urvara Crater (closeup)
Ridge at the center of Urvara Crater (closeup) Dawn took this picture on July 6 from an altitude of 72 miles (116 kilometers). This ridge is in the center of Urvara Crater. We saw a different section of the ridge, west of this scene (photographed on the previous orbital revolution), in the previous Dawn Journal. (We provided some additional context for this image then as well.) This scene is 5.3 miles (8.6 kilometers) across. Many large craters have a peak in the center. Urvara is more unusual in having a ridge. Note the patterns of bright material that apparently flowed downhill. Full image and caption. NASA / JPL-Caltech / UCLA / MPS / DLR / IDA
