What we do is we excavate down from the top, and we have ways of dating the different layers, primarily by the artifacts but also by the cultural events that we know that happen over time. One of the things to note here is that we have also found Native material in locations within the soil context that are fairly close to the surface, with the idea being, generally, that the older material is found close to the bottom but I think what this profile illustrates is that you don't have to have old stuff really, really deep down.
