Early Pleistocene alpine ice centres existed in west-central Yukon uplands. Paleo-equilibrium line altitude (ELA) data is provided for the Crag Mountain upland (1054 ± 96 m) and for the Reid (1391 ± 132 m) and McConnell (1488 ± 103 m) glaciations in the Ogilvie Mountains. The dataset, from the Government of Yukon, examines the marginality of cirque glaciation through the Middle and Late Pleistocene.
Use Cases
- Model paleo-climate conditions based on paleo-equilibrium line altitude (ELA) proxy data.
- Analyze glacial cirque degradation patterns based on descriptions of subdued cirque forms.
- Study the relationship between continental ice sheet growth and cirque glacier marginality based on the suggested precipitation-diverting mechanism.
- Map the spatial distribution of pre-Reid and later glaciation cirques based on the described geographic regions.
Strengths
- Includes specific paleo-equilibrium line altitude (ELA) measurements with error margins (± 96 m, ± 132 m, ± 103 m).
- Provides temporal context for glacial features, distinguishing Early Pleistocene (pre-Reid), Reid, and McConnell glaciations.
- Identifies specific geographic regions: Crag Mountain upland, Ogilvie Mountains, Dawson Range.
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 study area in west-central Yukon.
