Excavations were conducted in 1999 along the east side of Second Fort Crawford, a military fort in Prairie du Chien that was occupied from 1829 to
1835. Even though historic records and maps of the fort existed, the excavations revealed interesting differences in the configuration of the rooms as compared to the
historic map of the floor plan, and were able to clarify or expand on many aspects about frontier life.
Archaeologists look at all past cultures, even those that are not usually thought of as "archaeological." Historic
archaeology deals with sites and artifacts
that date to the period of time when written records are also available. In Wisconsin this is after about 1700 A.D., but in some parts of the world such as Greece or the
Middle East, written records have existed for thousands of years.
Written records would seem to eliminate the need for doing archaeological research with material remains. However, written records tell only part of the story about the past,
and that story is often biased or idealized from one perspective (that of the recorder). Thus, most histories, even diaries and personal journals, often won't record such
details as what people were eating, how they were preparing their food, what their lives were like. The archeology of historic sites provides powerful complementary
information to that provided by written records, particularly for segments of a culture that didn't record their own history, such as peasant classes.
Even with good records available, the archaeological evidence might be able to correct misinformation or fill in many details.
