Surficial Geology and Geohazards of the Greater Whitehorse Area, 1:15,000 Scale

Remote predictive mapping at a 1:15,000 scale details the surficial geology of the greater Whitehorse area, supported by field investigations from 2017 to 2021. The dataset includes ten map sheets and an aggregate potential model, with a focus on identifying geohazards like landslides, permafrost, and flooding. A robust summary of unprecedented 2022 landslide activity along the Whitehorse escarpment is also provided.

Use Cases

• Model landslide susceptibility based on mapped historical and recent landslide features.
• Identify areas with aggregate potential for gravel resource exploration using the provided model.
• Map permafrost distribution based on identified landforms in the surficial geology data.
• Assess flood risk by analyzing surficial geology units and terrain features from lidar.

Strengths

• Mapping is based on recent high-resolution imagery, primarily 2013–2019 lidar and 2007 air photos.
• Field investigations were carried out over four field seasons from 2017 to 2021.
• Includes a detailed summary of unprecedented landslide activity from early 2022.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
