Prehistory

How does the archaeologist know where to dig? Either local people have reported noticing artifacts on the ground-or in some regions, they have seen ruins-or the archaeologist has surveyed an area, walking over sections looking for artifacts. Frequently, in recent years, the survey has been conducted to meet government requirements to protect our cultural her­ itage: Before road or building construction can destroy historic or prehistoric remains, the area to be affected must be surveyed by a competent archaeologist, and, if significant remains are present, the construction should be rerouted if possible, and if not, the remains recorded and salvaged.
