Figure 2b. Field measured extent of channels, areas of estimated thick colluvium and landslide scars in a portion of the Mettman Ridge site shown in Figure 1. Border of area mapped also shown (field work done by D. Montgomery). All landslides occurred between 1987 and 1997 after clear cut logging. It was not always possible to separate failure scar from runout disturbance, so some elongate scars include both. Topographic base map has 5 m contours and is derived from a 2 m grid of the laser altimetry data.
