Aerial photograph showing a large part of Glen Ogle. The image was made by stitching adjacent 1 km by 1 km tiles before cropping to give approximately 4 km (vertical) by 3 km (horizontal) coverage; north is to the top. (From Winter et al. 2009.). Key: 1. North debris flow: (a) potential source areas, (b) debris track, (c) runout/ debris fan and (d) subsequent carriageway repair. 2. South debris flow: (a) potential source areas, (b) debris track, (c) runout/ debris fan and (d) subsequent carriageway repair. 3. Historic rock falls. 4.
