I worked for a private company in NW Arkansas. We did surveys, site testing, and full excavations. Our largest projects were surveying forest service land for logging contracts. We'd find, map, and record any prehistoric or historic resources located in the project area.
We also did archaeology for govenment-funded projects on private property, such as pipelines, proposed highway expansions, etc. If disturbance to the site was unavoidable, we'd test the site with limited excavations to determine if it was eligible for nomination to the National Register of Historic Places. Most times, especially with logging, the site area was simply flagged off with a buffer and avoided.
I worked as an archaeologist in Arkansas for over five years, then moved to New Mexico for the same type of work. Recently I switched 'careers' and am now a geologist on a drill rig in a natural gas field.
In Arkansas, some of the project I worked on that you might have heard of: the Two-Ton water line in NW Arkansas, the NOARK gas pipeline through the Ozarks, excavation for an nterstate interchange for a new hospital in Little Rick, excavations and surveys for the new north-south interstate in Western Arkansas.
