Q:why dose it take archaeologist many years to excavate a site?

Basically they have to work by hand. Going into a site, they do not know exactly where the artifacts will be...how deep, how close together etc. Also, the objects they seek can be very small. Using mechanical tools (excavators for example) can damage or destroy artifacts. They also want to map the locations of things they find, to see if there is a pattern...for example, finding a fire remnant and bones that show charring might indicate a kitchen given one pattern, or a massacre site given another. The closer they get to an object, the smaller the brush and the more delicate the handwork. There are other issues...the deeper one digs, the more you have to shore up the sides or widen them to avoid cave-ins...there are safety concerns. Also, most sites are not wasteland and they are tying them up from other uses, so permissions and agreements have to be obtained and kept. Many interesting sites have people living over them at the surface who would not appreciate having their house or business collapse because of an overzealous dig.

Q:We built our own house two years ago and moved in April 2008. We had the excavators back-fill after inspections. Since then the soil has been settling down to the point now I can see the top of the tar on the foundation. How long does this continue? It seems to have slowed down this past year, but it has messed up my plans of planting around my house. I want to put more dirt around the foundation to build it back up where it is suppose to be, but then I'd have to wait on that to settle. That is a lot of dirt. I'm debating on doing it myself or have the excavator come back in and do it for me.

Although the ground never finishes settling most settling will occur in the first 4 years. I suggest you fill in with dirt now and then again next season. Planting will help bind the dirt and can be started after this first fill.
