Dave Scott Swann Hills Photo

Apollo 15 commander Dave Scott photographs a rock sample on the slopes of Hadley Delta mountain. Note the rover in the background, which the astronauts had to take turns holding in place while the other explored.

The rover weighed substantially less than 100 lbs. on the moon and often threatened to tumble or slide down the mountainside. The slopes of Hadley were very powdery, burying the astronauts up to their ankles.

In the background are the Swann Hills, which Scott named after Gordon Swann of the USGS, one of the geology instructors.

Scott has signed and added "CDR Apollo 15".
