This research note documents a concept for describing a terrain by considering it to be a composite of individual representative landforms each of which has a unique distribution of slope-gradient frequencies. By identifying landforms along a hypothetical line of movement and assigning to them slope values derived by field measurements of similar landform types in another area, the total range and frequency of the slopes that would be encountered are predicted. The data of this report from glaciated features in central Massachusetts are intended only to implement presentation of the concept they give no more than initial ranges of slope-gradient values for the seven features considered. Additional field measurements would extend and refine these ranges and could consider other features and other terrain factors of worldwide environments.
