Landslide Processes in Yukon Permafrost, 2004 Field Study

A terrain evaluation study identified over 35 areas of landslide activity in the Little Salmon Lake area of central Yukon. Field work in summer 2004 provided ground truth and characterized prominent landslides. The dataset likely contains observations on four distinct landslide processes: debris flow, rock slumping, bimodal flow, and multiple retrogressive slumping.

Use Cases

• Model slope stability hazards based on terrain evaluation studies.
• Characterize landslide processes like debris flows and retrogressive slumping based on field observations.
• Assess development risks in discontinuous permafrost zones based on identified landslide activity areas.

Strengths

• Terrain evaluation identified over 35 areas of landslide activity.
• Field work in summer 2004 provides ground truth for terrain evaluation.
• Focuses on four distinct landslide processes: debris flow, rock slumping, bimodal flow, and multiple retrogressive slumping.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific Yukon study area.
