as16-107-17473.JPGAS 16-107-17473 - The "Sample Container"77 visiteThis picture is showing the Rover in the background, while the SCB that John Young brought to hold individual sample bags is in the foreground. Charlie is at the back of the Rover. Note the footprints that John made as he made his way up to the Station 4 Crater.

as16-107-17483.JPGAS 16-107-17483 - Station 4 Crater (ejecta crater)65 visiteStation 4 crater. Note that there is very little debris on the Western (right) side of the Crater. As John Young recognized in the field, this crater was almost certainly formed by a large piece of highly-shocked ejecta from South Ray Crater which plowed into the side of Stone Mountain at relatively low velocity and came apart.
Hence, this is a Secondary Crater.
Notes (from "Glossary of Geology", 2nd Edition, American Geological Inst., Falls Church (VA) - 1980)
Ejecta — The material thrown out of an impact crater by the shock pressures generated during the impact event. Ejecta generally covers the surface around an impact crater to a distance of at least one crater diameter, with individual streamers of material extending well beyond this distance ("rays"). The ejecta blanket of a crater becomes less visible with increasing age of the crater.
Secondary craters — Craters produced by the impact of debris thrown out by a large impact event. Many secondary craters occur in clusters or lines where groups of ejecta blocks impacted almost simultaneously.MareKromium

Note the spray of dirt propelled toward us by backward motion of Charlie's left heel. Note, also, the large rock at the lower right that John drove over just before stopping the Rover.
The Rover chassis clearance is about 14" (35 cm)".
