Second of a three-frame minipan taken by David Scott of the Station 9 crater bench, prior to leaving. The small, fresh crater is located about 100 meters east of Hadley Rille. The crater is filled with blocks of compacted soil, known as regolith breccia or "instant rock".
Although it is tempting to think that the break in slope represents the point at which the impactor encountered basaltic bedrock beneath the overlying regolith, that explanation is unlikely because Dave and Jim found no basaltic ejecta from this crater.
