Glacier and rock glacier changes since the 1950s in the La Laguna catchment, Chile

to related objects

Abstract - 25.2 ± 4.6  % between 1956 and 2020, while the mass balance of Tapado Glacier has become steadily more negative, from being approximately in balance between 1956 and 1978 (- 0.04 ± 0.08  m w.e. a- 1 - 0.32 ± 0.08  m w.e. a- 1 - 0.54 ± 0.10  m w.e. a- 1 between 2012 and 2015. The rock glaciers within the La Laguna catchment show heterogenous changes, with some sections of landforms exhibiting pronounced elevation changes and surface velocities exceeding that of Tapado Glacier. This could be indicative of high ice contents within the landforms and also highlights the importance of considering how landforms can transition from more glacial landforms to more periglacial features under permafrost conditions. As such, we believe high-resolution (sub-metre) elevation changes and surface velocities are a useful first step for identifying ice-rich landforms.
