Sunnydale Landslide Monitoring Data from Yukon River

Aerial lidar data from 2014, 2018, 2019, 2020, and 2022, along with physical monitoring stations, track a slow-moving rock-slope deformation across from Dawson, Yukon. The dataset documents movement rates up to 11 cm/yr, road subsidence, expanding tension cracks, and rockfall. It is produced by the Government of Yukon and includes ongoing terrestrial lidar analysis and near-real-time monitoring installed in early 2023.

Use Cases

• Model landslide hazard probability based on documented acceleration rates and movement trends.
• Analyze geomorphological change over time based on detailed maps of surficial geology.
• Monitor deformation progression based on data from physical monitoring stations and lidar differencing.
• Assess infrastructure risk based on documented road subsidence and expanding tension cracks.

Strengths

• Multi-year lidar coverage from 2014 to 2022 provides a longitudinal view.
• Movement rates are quantified up to 11 cm/yr across the slide area.
• Includes detailed geomorphological and surficial geology maps produced from field mapping.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Limited data precludes certainty on probability and timing of rapid failure, as noted in the description.
