This Apollo 15 photo shows how NASA began to incorporate mountains in the background, as the fake pictures they put forward for the 11, 12 and 14 missions, were bland and uninteresting.
They assumed it would renew public interest, as the public had become bored by it all. So an impressive background scene was built up in various stages, and used as a wide pan photo shot for the 17th mission, ie, the Grand Finale.
Notice large sloping mountain to the right of the hill, has disappeared in this picture. Looks as though NASA have been busy with the heavy earth moving equipment again.
Notice LM is in WIDE OPEN SPACE, ie, flat open plain land, however in the picture below, which is also Apollo 15, the LM is shown to be surrounded by towering mountains and hills.
