Simulated lahar arrival times and maximum depths in the Middle Fork Nooksack River drainage, resulting from hypothetical landslide sources on the western summit of Mount Baker, Washington

This data release contains postprocessed D-Claw model output, simulation configuration, and provenance information for six hypothetical lahar scenarios at Mount Baker, Washington. The modeled scenarios evaluate the influence of landslide source volume and material properties on lahar dynamics, inundation, and runout in the Middle Fork Nooksack River drainage. The numerical simulations and scientific interpretation are documented in Gardner and others (2025). This release is the second of two U.S. Geological Survey data releases supporting the Mount Baker D-Claw modeling study. The companion data release (https://doi.org/10.5066/P1PEX7FS) contains the digital elevation models used to construct the computational domains together with selected hazards-assessment products. Those DEMs are intentionally not redistributed here. The present release provides the complete collection of published derived products for the six modeled scenarios, including arrival-time maps and maximum-depth maps, together with multiband model output, simulation configuration (setrun.py), provenance information, and visualization products. Each published product is identified by both a ScenarioID, identifying the modeled scenario, and a RunID, identifying the specific D-Claw execution that produced the archived results. The simulations were performed using the D-Claw model (George and others, 2025). Additional documentation is provided in README.md and DATA_ORGANIZATION.md.
