Aboriginal sites and appropriate conduct.

G'day.
A quick question which was prompted by a photo of a midden in another thread.
If I was to come across one of these middens I am not sure I would be able to recognise it for what it was or know what the appropriate behavior is towards them.
So, how does one generally recognise a location which might have some sort of heritage value and what is to be done about it? Do you give it a wide berth or appreciate it without interfering with it or something else entirely?
I am assuming I am not the only one who is ignorant of such things so this thread may be of interest to others too.
Cheers.
