Piedmont glaciers, also called ‘piedmont lobes’, form where constrained valley glaciers and outlet glaciers reach open lowland areas and are able to spread out laterally, whereby they take on a characteristic tear-drop or lobate shape due to the flow of the ice (Figure 6).They typically occur at lower altitudes (i.e., in ablation areas) and generally form glacier termini.
