GeoRoundup: the highlights of EGU Journals published during December!

Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we put the journals that publish science from those Divisions at the top of the Highlights roundup. For December, the Divisions we are featuring are: Geodynamics (GD),  Geomorphology (GM) and Soil System Sciences (SSS). They are served by the journals: Biogeosciences (BG), Earth Surface Dynamics (ESurf), Geoscientific Instrumentation, Methods and Data Systems (GI), Hydrology and Earth System Sciences (HESS), Natural Hazards and Earth System Sciences (NHESS), Nonlinear Processes in Geophysics (NPG), SOIL, Solid Earth (SE) and Geoscientific Model Development (GMD).


Featured highlights

Earth Surface Dynamics:

Alpine hillslope failure in the western US: insights from the Chaos Canyon landslide, Rocky Mountain National Park, USA – 4 December 2023

In this paper, we investigate the 28 June 2022 collapse of the Chaos Canyon landslide in Rocky Mountain National Park, Colorado, USA. We find that the landslide was moving prior to its collapse and took place at peak spring snow melt; temperature modelling indicates the potential presence of permafrost. We hypothesize that this landslide could be part of the broader landscape evolution changes to alpine terrain caused by a warming climate, leading to thawing alpine permafrost.
