Astronauts went to many different places from the mid 60s right up until the end of Apollo in 1972, for their so called training simulations. Picture on right shows just one such place, known as Blackhawk Slide.
It's easy to see why they used such places for taking fake Moon pictures. Just remove those few shrubs in the foreground, (should take about half an hour), and you have your perfect fake Moon setting. Not only that but you already have your 'orange soil' in place for Mr. Schmitt to quote his famous remark "There's orange soil here, orange soil on the Moon." Both Cernan, and Schmitt were here on 6 Oct 1972 to record their 'Moon Game'.
