Four different Pequea Valley High School classes, including the Advanced Placement U.S. History class, recently visited a local archaeological dig. This is an exploratory dig in anticipation of a new bridge being built.
The archaeologist talked to the students about how people's knowledge of history can be dramatically changed just by finding new evidence in one key area. Students were shown the proposed blueprints for the new bridge, as well as older maps dating back to the 1800s that show a bridge in that area. Students also were able to see the soil layers.
The students are just finishing a unit about the Revolutionary War and how Lancaster County was involved in this conflict. Students learned that the topmost layer of soil from that period is now approximately three feet deep below ground and that the area was at one time covered with trees.
