Statistical Prehistoric Landscape Sensitivity Model Worksheet

Use the following statistical prehistoric landscape sensitivity worksheet to evaluate the relative likelihood of finding traces of significant prehistoric sites at any given point in southern New England. Make one selection within each of the eight environmental categories, then add for a total score ranging between 0-100. Scores above 20 indicate a moderate to high sensitivity for the potential presence of prehistoric sites.
