| Summary: | Advanced methodologies such as core drilling, borehole logging/monitoring, geophysical tomography, high-precision photogrammetry, laser altimetry, GPS/SAR surveying, miniature temperature data logging, geotechnical laboratory analyses, numerical modelling, or GIS-based simulation of spatial distribution patterns in complex topography at regional to global scales have created a rapidly increasing knowledge basis concerning permafrost in cold mountain ranges. Based on a keynote presentation about mountain permafrost at CFG8 in Obergurgl 2012, a brief summary is provided concerning primary research frontiers and the long-term challenge related to the increasing probability of far-reaching flood waves in high-mountain regions originating at newly forming lakes as a consequence of large rock falls and landslides from destabilising steep rock walls with conditions of warming and degrading permafrost often in combination with de-buttressing by vanishing glaciers. Research is especially intense in the densely populated European Alps. |
