This report provides a summary of both the lessons learned from the Turtle Mountain monitoring system (TMMS), and from studies undertaken by the Alberta Geological Survey (AGS) and collaborators between January 1 and December 31, 2019. The TMMS is a near–real-time remote monitoring system that provides data from a network of sensors and monitoring campaigns on Turtle Mountain, located in the Crowsnest Pass of southern Alberta. As of April 1, 2005, the AGS took ownership of this system, and the responsibility for long-term monitoring, interpreting data, and notifying the Alberta Emergency Management Agency should significant movements occur. Since that time, Turtle Mountain has been the site of ongoing monitoring and research focused on understanding the structure and kinematics of movements on the unstable eastern slopes. As this site provides a rich dataset and optimal conditions for the application of new and evolving warning characterization technologies, the site has been termed the ‘Turtle Mountain Field Laboratory’. As part of this responsibility, the AGS performs an annual detailed review of the data stream from the TMMS. To help in this interpretation, the AGS initiated specific studies to better understand the structure of the mountain and its relationship to the style and rate of movement seen in recent and historical deformations of South Peak. These studies also better define the unstable volumes of rock from the South, North, and Third Peak areas.

This report comprises five main sections:

  • The first section contains information about the significant changes to the TMMS’s network during 2019. This includes a review of the main repair and maintenance activities and a summary of system performance and reliability.
  • The second section provides the analysis and interpretation of data from the primary monitoring equipment, known as LiSAmobile.
  • The third section discusses supporting studies and research.
  • The fourth section contains information on the emergency preparedness documentation and collaborations with external government agencies on the Turtle Mountain Monitoring Program. In addition, the Alberta Energy Regulator (AER) hosted an internal workshop on emergency response principles and best practices.
  • The last section features information on two videos produced by the AER to highlight work completed on Turtle Mountain in 2019.
