Planet of the Apes (1968) Question

[Eye Candy]

I re-watched Planet of the Apes (1968) and I have a couple of questions:

1. When the "scarecrows" are seen, are they facing toward the Forbidden Zone or away from the Fordbidden Zone? In other words, are the scarecrows specifically mounted to scare people from going into the Forbidden Zone, or to scare people from coming out of the Forbidden Zone into the Apes territory ?

It seems to me that the scarecrows are facing the Forbidden Zone, to scare people from entering Ape territory, so the apes don't really seem to care if any humans go into the Forbidden Zone, because the humans would probably die before they could find sustainence.

2. At the end of the movie, just before we see the top of the statue of Liberty, do we have any idea of what we see that is "metal" that is shown ??

If you don't know, or don't have any idea, or just don't care..... then please don't bother to reply.
