65767 is a glassy object containing relatively large white clasts and was collected as a rake sample. The white clasts are ferroan anorthosite which have been described as pristine. Rotation 1 highlights the shocked nature of the anorthosite. Rotation 2 shows the devitrified nature of the glassy coating.
The sample weighed 17.5 grams before analysis and has not been dated.

Note the glass slide on which this sample is mounted has been scribed with the numbers 1-4. The embedding resin appears to have begun to decompose - hence the circular dendrite growths.
The Apollo 16 landing site was in the hilly region around Descartes crater in the lunar highlands. The landing spot was chosen to allow the astronauts to gather geologically older lunar material (Descartes Formation and the Cayley Formation) than the samples obtained in the first four landings, which were in or near lunar maria.
The mission lasted 11.1 days, with a stay on the lunar surface of 71 hours. The crew were on the lunar surface for 20.2 hours during which they traversed approximately 27 kilometers and collected approximately 96 kilograms of samples.
Apollo 16 was launched on 16 April 1972.
