The Peace River Lowlands of Alberta and British Columbia is one of the most historically active mass-movement areas in western Canada. Alberta Geological Survey (AGS), in collaboration with other stakeholders, has initiated a multiyear study, centred on the town of Peace River, to develop a better understanding of the type and extent of landsliding within the municipality. To help establish the geological setting for these landslides, AGS conducted a drilling program using rotosonic coring, wet-rotary drilling and downhole geophysics.

This report details the drill program and contains borehole logs with descriptions of the encountered lithology. The lithological descriptions include geophysical logs and select core photographs in two of the four borehole locations. In addition, the report defines the methodology developed to classify discontinuities in the core samples.
