and all future groups of astronauts who went to the moon came to flagstaff to train.he field, several meyer roots from downtown -- several miles from downtown flagstaff, not far from meteor crater, this field has senders from the explosion. when astronauts were training here, they went to sunset crater and meteor crater and grand canyon and other places, but nasa realized they wanted another place to train, something that was more accurate for the lunar surface in terms of crater. usgs, based on an image from the moon, created this crater field. they dug holes with a back at different depths, filled them with explosives to create different sized craters, and 400 plus craters were made here. they set the charges, blew them up in this cataclysmic explosion, senders flew up in the air and then settled down. they took aerial photos and realized this was really effective, at really did look like craters on the moon in terms of, not necessarily the exact geology, but the orientation of the craters and everything. from 1968 through 1972, astronauts came here for training. ,
