What is dug up may be analyzed by a metal detector for stray finds but unless of course the excavation site has always been untouched for a lengthy period of time, there can be a tiny layer of modern day material on the exterior that is of limited archaeological interest. In farm areas, any kind of archaeological features should be noticeable beneath the surface. With urban areas, they may be thick layers of human deposits and only the uppermost will be visible to the naked eye. With either case, the first task is drawing a scaled site plan which will show the edges of the excavation. This strategy can be composed using tape measures, or as its much more common these days, an electronic total station. A grid is typically set up, to divide the site. Excavation is also useful for digging out houses and trenches. When clearing dirt out for roads or sub divisions, excavation is what takes care of things.

There may be a lot to find out with excavation, as you'll need to know just how to run an excavator machine, shoot grade, and exactly how to properly dig holes and trenches so they won't cave in.
