Apollo 17 Astronaut Schmitt samples the boulder at Station 7

Apollo 17 Astronaut Harrison H. Schmitt samples the boulder at Station 7 located at the base of North Massif in the Taurus-Littrow valley.  This large boulder was dislodged by a strong moonquake that occurred about 28.5 million year ago.  The source of the quake was likely from an event on the Lee-Lincoln fault. The picture was taken by astronaut Eugene A. Cernan, Apollo 17 commander.
