Fig. 4.

3-D rendered image from UAV DEM data at the initiation of the north lobe, which aligns with the start of transect E (Fig. 1c). The image is looking up-flow to accentuate the festoon texture seen in the foreground, which is identified with the black arrow. The background displays the rubble levees of event 2 aʻa flows. Numbers after transect label E refer to GPS locations (see Additional file 1: Sheet 7)
