Like the guy in Oklahoma said, pottery is a good indicator of a village site. Looking at what you've shown here, I'd say that the spot was somewhat temporary, but, most "campsites" were used over and over again over a period of hundreds and thousands of years, here in N.E. Texas for example, most sites will produce points from Paleo and Early Archaic times, right up through Late Caddoan (1700's).
Farther west, of course, its mostly temporary camps, but they were used over and over again, and produce a wealth of artifacts.
Dont be surprised if yall dont stumble across a potsherd or two, or maybe an arrowpoint.
Hope this helps.
