ABSTRACT
Following the 1998 study, a geotechnical hazard assessment of the south flank of Frank Slide was undertaken by BGC Engineering (2000). The assessment included a site reconnaissance partly to confirm the geological structure and fissure patterns in the South Peak and to assess the state of the existing instrumentation on Turtle Mountain. Six of Allan’s original 18 gauging stations were identified and aperture measurements taken. No significant displacements were interpreted from these measurements. It was observed that the TM-71 Moiré crack gauges had been completely destroyed through vandalism.
