Before Apollo 11, nasa spent a lot of time getting astronauts to try to navigate to a simulated lander out in the desert. They used explosives to make a scale version of a lunar field, dropped astronauts off, and had them try to navigate to the lander.

If I remember right, only a couple people were able to even identify where they were on the map, let alone find the lander again. Lunar surfaces are just so unnatural that human instincts about size and scale tend to get you in more trouble than not.
