Moon Walk - Preparation in Arizona

How did fighter pilots, who became astronauts, prepare to walk on the moon?  How could those individuals, untrained in geology, make geological observations? 

In this clip from The Planets, see how a section of Arizona was “converted” into an area of lunar-type craters, thereby allowing moon-bound men to prepare for their upcoming Apollo missions.
