YEARS THURBER ENGINEERING LTD. YEARS Photo 1. Backscarp of the 2+500 slide. Some additional, relatively minor erosion has occurred in the backscarp near the road, though significant additional movement has occurred at the north margin of the slide (left of the picture). Also note the shallow skin failures on the slope above the highway in the background. (May 2007) Photo 2. Backscarp of the 2+500 slide (Photo provided by AIT, taken in Sept 2007). This portion of the slide has retrogressed significantly since our visit in May, and is estimated to be only 3 m to 5 m away from the guardrail. Also note the re-graded skin failures with subsequent cracking and movement between 2+200 and 2+300 in the background.

Photo 3. Looking south along the road at the Sta. 2+500 slide (photo provided by AIT, taken in Sept 2007). The location of SI-27 is indicated by the arrow – this was the furthest upslope extent of sliding in May 2007 – note the subsequent retrogression of the northern part of the slide (foreground).
Photo 4. Significant downslope movement of the new slide block to the south of the main Sta. 2+500 slide. The block has shifted downslope by more than 5 m since 2006. (May 2007)

Photo 5. Looking downslope across the flowslide mass from the Sta. 2+500 slide. Some ponds with water exist on the uneven topography.
Photo 6. Looking south along the backscarp of the Sta. 2+500 slide. Note how close inclinometer SI27 is to the backscarp (arrow).

Photo 7. Culvert at around Sta. 2+650. The upstream end of the culvert is plugged. Downstream, the channel has suffered erosion in the past, and joins the main Sta. 2+500 slide area at the margin of the trees.
Photo 8. South end of the skin failures above the highway. These have worsened and expanded slightly since 2006. Since our inspections, these have been re-graded, some RECP placed, and a trail of driven fence post “soil nails” started to see if the surficial soil can be reinforced.

Photo 11. Crest of the slope to the north of the Elephant Trunk. The near surface skin of soil and grass has slipped downslope.
Photo 12. The debris from the skin failures flows down hill and has formed lobes at the base of the slope.

Photo 13. Skin failures and flowslides downhill of the highway, looking towards the Elephant Trunk.
Photo 14. Looking north along the slope below the highway. There are a series of small failures along the crest with associated flowslides.
