Turtle Mountain Field Laboratory, Alberta (NTS 82G): 2012 Data and Activity Summary

The Turtle Mountain monitoring system is a near-real-time monitoring system that provides data from a series network of more than 80 geotechnical sensors on the south peak of Turtle Mountain (site of the 1903 Frank Slide) in the Crowsnest Pass, Alberta. Alberta Geological Survey (AGS) is responsible for the long-term monitoring and interpretation of these data. It also notifies the Alberta Emergency Management Agency should significant movements occur.

This report has two main chapters:

Chapter 2 lists the major changes to the physical sensor network of the monitoring system during 2012. This includes a review of the main repair and maintenance activities, a summary of new installations and overall system performance and reliability.

Chapter 3 details the interpretations of slope conditions and displacement behaviour from instrumentation results. As weather conditions affected some of the sensors, the report focuses only on the sensors that have provided reliable annual data. Displacement results from ground-based interferometric synthetic aperture radar monitoring of South Peak are also provided.
