Earth's Moon - Apollo 12

One of the odd mounds seen by the Apollo 12 astronauts on the Moon

This is an image of one of the peculiar mounds which were seen around Head crater at the Apollo 12 landing site. The mound is described by Bean as "about 4 feet high and, at the top it's about 5 feet across..." It is roughly 4 to 6 meters in diameter at the base. The mounds are thought to be clumps of regolith thrown out of craters during impact which have slowly formed into their present shape by small meteorite bombardment over time. This southwest looking photograph was taken by commander Charles "Pete" Conrad on the first moonwalk EVA. (Apollo 12, AS12-H-46-6795)
