Rock glaciers represent hidden water stores in the Himalaya
, 2021 In the high mountains of Asia, ongoing glacier retreat threatens human and ecological systems through reduced water availability. Rock glaciers are climatically more resistant than glaciers and contain valuable water volume equivalents (WVEQ).

DETECTION AND QUANTIFICATION OF ROCK GLACIER CREEP USING HIGH-RESOLUTION ORTHOIMAGES OF VIRTUAL GLOBES [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 Rock glaciers are creep phenomena of mountain permafrost and are composed of ice and rocks. Active rock glaciers move downslope by force of gravity. Maximum creep/flow velocities of individual rock glaciers may vary from a few centimeters up to several

Antarctic Record, 1998 Part of the debris slopes previously defined as alpine moraines at the foot of Mt. Riiser-Larsen were considered to be active rock glaciers in terms of longitudinal profiles, degree of weathering, size of surface boulders and morphological similarities ...

Incorporating InSAR kinematics into rock glacier inventories: insights from 11 regions worldwide [PDF]
The Cryosphere, 2022 Rock glaciers are landforms related to permafrost creep that are sensitive to climate variability and change. Their spatial distribution and kinematic behaviour can be critical for managing water resources and geohazards in periglacial areas.

Comment on “Ice content and interannual water storage changes of an active rock glacier in the dry Andes of Argentina” by Halla et al. (2021) [PDF]
The Cryosphere, 2023 Recently published work on water preservation in Chile assumes that “permafrost” (cryogenic) rock glaciers are dominant. Melt pond development shows that rock glaciers are glacier-derived (“glacigenic”) rather than of permafrost origin.

Mountain glacier-to-rock glacier transition
Global and Planetary Change, 2019 Abstract In many of the world's high mountain systems, glacier recession in response to climate change is accompanied by a paraglacial response whereby glaciers are undergoing a transition to rock glaciers. We hypothesise that this transition has important implications for hydrological resources in high mountain systems and the surrounding lowlands ...

A review of topographic controls on moraine distribution [PDF]
, 2014 Ice-marginal moraines are often used to reconstruct the dimensions of former ice masses, which are then used as proxies for palaeoclimate. This approach relies on the assumption that the distribution of moraines in the modern landscape is an accurate ...

Glacial decline next to stable permafrost in the Dry Andes? Vertical glacier surface changes and rock glacier kinematics based on Pléiades imagery (Rodeo basin, 2019–2025) [PDF]
The CryosphereThe presence and volume of high-mountain cryospheric features are drastically affected by rising air temperatures – on global scale. In the Dry Andes, precipitation is extremely scarce, shifting the hydrological significance towards the solid water ...

Is that a relict rock glacier? [PDF]
Geomorphology, 2019 The distribution of rock glaciers is often used to investigate the occurrence of permafrost in mountain areas and to understand their climate and paleoclimate evolution. This requires the creation of regional and global inventories capable of discriminating active and relict landforms in order to forecast the presence or absence of ice in the ground ...

Arctic, Antarctic, and Alpine Research, 2018 Little is known about the presence, distribution, age, or activity of rock glaciers in the British Columbia Coast Mountains of western Canada. Reflecting debris accumulation and mass wasting under a periglacial climate, these rock glaciers describe a ...
