Abstract

The latitudinal-altitudinal distribution of rock glaciers in the dry Chilean Andes between 27° and 33°S was analysed and their hydrological and geomorphological significance evaluated. Statistical estimation techniques were used based on digital elevation models and air photo interpretation, and sediment budget models were applied to assess surface-lowering rates. Results and discussion about rock glacier distribution limits, hydrological significance, estimation uncertainties in glacier and rock glacier volumes, and geomorphological significance
