Permafrost Conditions Beneath Yukon Infrastructure in Dawson and Ross River

Investigations conducted by the Government of Yukon assess permafrost degradation affecting critical buildings. Geophysical surveys and borehole drilling reveal warm, ice-rich permafrost beneath Dawson's Palace Grand Theatre, unfrozen sediment under the Old Territorial Administration building, and a deep thawing active layer at Ross River School. The dataset includes findings from DC resistivity, ground penetrating radar, and borehole data.

Use Cases

• Model infrastructure vulnerability based on geophysical survey results
• Map permafrost variability based on borehole and active layer observations
• Analyze thaw contributions from building drainage systems based on survey indications
• Assess structural risk for specific buildings based on subsurface condition descriptions

Strengths

• Focus on specific critical buildings (Palace Grand Theatre, Old Territorial Administration building, St. Andrew's Church, Ross River School)
• Combines multiple investigation methods (DC resistivity, ground penetrating radar, borehole drilling)
• Explicitly links permafrost conditions to infrastructure integrity

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 open_canada
