Much of the activity at station 4 was devoted to the boulders shown in this photograph. These boulders are basalts and represent material excavated during the formation of Dune Crater. The crew reported that vesicles were abundant in the boulders at this location and that some vesicles were as large as 9 cm in diameter. The abundance and size of the vesicles in these boulders suggest that this basaltic material cooled on or very near the lunar surface.
