The archaeologists worked for the housing development people. The dug some trenches with a back hoe to look around, but like I said before, these sites are often very large, so they never dig up the entire place. Artifacts can always be found left behind, simply because there are so many of them. Its not uncommon to see hundreds or even thousands of pottery sherds laying on the surface out here. Then you combine that with the amount of lithic debris, and there is just stuff everywhere. The archaeologists are looking for museum quality stuff to preserve, not just anything I guess. I didnt get his first name, but the foreman guy or manager (whoever he was) said he has found some interesting stuff from time to time, but he didnt go into specifics.
