Ashbrook is a large impact crater near the South Pole on the far side of the moon and therefore cannot be directly observed from Earth. Its eastern flank is overlaid by the equally large Drygalski crater , and more than half of its interior is buried under the ramparts and ejecta of Drygalski. Zeeman Crater extends northwest .
The remaining outer wall of Ashbrook is worn and badly eroded by subsequent impacts, but the original formation can still be seen. Only part of the crater floor near the southwestern rim is flat and only marked by a few small impacts. If the crater had a central peak, it is now covered by ejecta from Drygalski.
Before Ashbrook was given its own name by the International Astronomical Union (IAU) in 1994 , it was known as "Drygalski Q".
