The goal of this research was to develop methods for identifying indicators of historic and prehistoric surface
hydrologic features in available Geographic Information System (GIS) data to create a GIS layer representing relict
hydrography for inclusion in Mn/Model, Mn/DOT’s statewide archaeological predictive model. This research
addresses the limitation imposed on the current predictive model by the absence of historic and prehistoric surface
water features, such as drained lakes and wetlands. Because several important variables are derived from surface
hydrography in Mn/Model, the use of historic/prehistoric hydrologic features, instead of strictly modern features,
will greatly improve its predictive accuracy. This research resulted in an automated tool, developed using ArcGIS
ModelBuilder and based on ESRI ArcGIS ArcInfo 9.2 (ESRI 2005), that can be used on any county in the state
where the input data are available.
