The Fifty Mile Creek area in west-central Yukon contains previously unrecognized glacial erosional and depositional landforms, including cirques and end moraines. These features, similar to those in the adjacent Yukon-Tanana uplands of Alaska, formed during the Eagle glaciation (>40 ka). Glaciation influenced runoff and terrace formation, with placer gold occurring along Fifty Mile Creek and its tributaries, as well as in the lower-level terraces.
Use Cases
- Map glacial landforms based on descriptions of cirques, u-shaped troughs, and moraines.
- Model fluvial terrace formation cycles based on described climate-controlled runoff variations.
- Identify potential placer gold deposits based on locations along Fifty Mile Creek and its tributaries.
- Compare glacial evidence with the adjacent Yukon-Tanana uplands of Alaska.
- Analyze cycles of aggradation and incision in the Fifty Mile Creek drainage.
Strengths
- Identifies specific glacial landforms (cirques, end moraines) and their age (>40 ka).
- Describes the spatial occurrence of placer gold along Fifty Mile Creek and its tributaries.
- Links landform formation to the Eagle glaciation and compares them to features in Alaska.
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 Yukon.
