Permafrost Disturbance and Recovery in the Klondike Goldfields, Yukon

A cryostratigraphic record documents permafrost degradation and recovery following historic surface disturbances at a site in the southern Klondike goldfields. The investigation reveals three distinct ages of disturbance and recovery potentially spanning the last century, including a recent burn (2004), a 1970s disturbance, and an older early 20th-century thaw event. This dataset was published by the Government of Yukon and was last updated on 2026-04-17.

Use Cases

• Modeling permafrost recovery rates based on documented disturbance events from the 1970s and 2004.
• Analyzing the role of vegetation cover in permafrost aggradation based on evidence from the described forest and burned sites.
• Investigating legacy impacts of early 20th-century deforestation on thaw depth based on the described ~2 meter thaw event.

Strengths

• Documents three distinct ages of permafrost disturbance and recovery potentially spanning a century.
• Includes a specific measurement of a historic thaw depth of approximately 2 meters.
• Explicitly links permafrost recovery to vegetation succession and specific disturbance events (e.g., 2004 fire).

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 a single site in the Klondike area.
