Short summary
We created the first empirically calibrated high-resolution map of mountain permafrost distribution in mainland Chile. Using field evidence from rock glaciers and boreholes with climate and terrain data, we found that more than 8000 km², mainly in the dry Andes of northern and central Chile, offer suitable conditions. Permafrost affects water resources, slope stability, and infrastructure, and our model provides a baseline for planning and future research under climate change.
