Abstract. Monitoring of the periglacial environment is relevant for many disciplines including glaciology, natural hazard management, geomorphology, and geodesy. Since October 2022, Rock Glacier Velocity (RGV) a new Essential Climate Variable (ECV) product within Global Observing System (GCOS). However, geodetic surveys at high elevation remain very challenging due to environmental logistical r...

A series of polygon networks has been discovered on the most recent LiDAR (Light Detection and Ranging) DEM (Digital Elevation Model) Flanders (Belgium) available in a resolution 1 m2. They are located sandy Campine area (northern Belgium) resemble thermal contraction crack from present-day permafrost regions. Different network types were observed, ranging orthogonal to hexagonal various combin...

Talus slopes origin is connected both with weathering and transport of the rock grain. The formation these landforms an effect many climatological, morphological geological factors. grain size surface talus slope brings some information about way deposition mechanisms. main aim paper to present different in two mountain locations - arctic periglacial semi-arid continental climate zones.

[1] We present observations of seasonal variations in polygonal crack patterns located in a polar trough on the south polar cap of Mars; previously, there was no direct observation showing that these patterns change. Polygonal patterns on Mars are attributed to thermal contraction cracking, which is commonly observed in periglacial environments on Earth. In this paper we discuss observations ba...
