Western Cordillera Paleoclimate Evidence During the Last Glaciation

Paleoecological evidence from the western and northern Cordillera tests assumptions about glacial climate conditions. The dataset likely contains pollen, plant macrofossil, and beetle data from periods including the Olympia interval (>59 to 25-29 ka) and the 18-19 ka Fraser/Puget Lowlands. It was published by the Government of Yukon and last updated on April 17, 2026.

Use Cases

• Test hypotheses about glacial climate variability based on paleoecological proxy evidence.
• Correlate regional warm/moist events like the Hanging Lake thermal event using pollen and beetle data.
• Analyze drivers of ice sheet advances based on paleobotanical moisture and cooling indicators.
• Model past vegetation mosaics and large mammal habitats in eastern Beringia from plant community evidence.

Strengths

• Evidence spans multiple proxy types including pollen, plant macrofossils, and beetles.
• Analysis covers a specific time range from >59 ka to around 18-19 ka.
• Data is sourced from a government organization and licensed under OGL-CA-2.0.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description suggests inferences require further testing, indicating potential uncertainty.
