Lidar-Based Detection and Interpretation of Glaciotectonic Features of the Morainic Topography of Finland

Figure 19

Within main ice lobes or streams the glaciated terrain is often divided into smooth looking, abrasive drumlin highlands and into rough erosional lowland zones, where the erosion has happened firstly by glaciotectonism and plucking. Elevation differences between high and low zones are quite small, at most cases 5–50 m. GT = glaciotectonic zone. DR = drumlin field.
