Late Wisconsinan McConnell Ice-Flow Patterns in Yukon's Pelly Mountains

Government of Yukon data describes the McConnell glaciation phases (ca. 24-11 ka) in the Pelly Mountains of southern Yukon. It details four phases of ice accumulation, expansion, and retreat, including the onset in cirques above 1524 m a.s.l. and the dominant glacial dispersion trajectory for drift prospecting.

Use Cases

• Modeling glacial dispersion trajectories for drift prospecting based on described ice-flow phases.
• Analyzing the relationship between ice-divides and Cordilleran ice lobe invasion patterns.
• Mapping sediment distribution patterns based on the described phases of ice accumulation and retreat.
• Studying the chronology of local glacier expansion and retreat in cirques above 1524 m a.s.l.

Strengths

• Describes a specific glaciation event (McConnell) with a defined time range of approximately 24-11 ka.
• Details four distinct phases of ice-flow and sediment distribution.
• Provides specific elevation thresholds for ice accumulation (1524 m and 1600 m a.s.l.).

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 Yukon region.
