The geography of rock glaciers in the American West

open access: yesArctic, Antarctic, and Alpine Research
Rock glaciers are relatively common in conterminous United States west of the 100° meridian, yet their distribution and number are not well known. Using aerial and satellite imagery, we inventoried the population of rock glaciers, yielding 2,257 rock ...

Spring-water temperature suggests widespread occurrence of Alpine permafrost in pseudo-relict rock glaciers [PDF]

open access: yesThe Cryosphere
Runoff originating from ground ice contained in rock glaciers represents a significant water supply for lowlands. Pseudo-relict rock glaciers contain patchy permafrost but appear to be relict, and therefore they can be misinterpreted when using standard ...

Rock Glaciers [PDF]

open access: yes, 2022
Rock glaciers, a key element of alpine mountain geomorphic systems, consist of coarse surface debris that insulates an ice-core or ice-debris mixture. Rates of movement of active rock glaciers vary from 1 to more than 100 cm yr–1.

Inventory and Distribution of Rock Glaciers in Northeastern Yakutia

open access: yesLand, 2020
Rock glaciers are common forms of relief of the periglacial belt of many mountain structures in the world. They are potential sources of water in arid and semi-arid regions, and therefore their analysis is important in assessing water reserves.

Rock glaciers in central Patagonia [PDF]

open access: yesGeografiska Annaler: Series A, Physical Geography, 2018
Active rock glaciers are ice and debris-cored landforms common in cold arid mountains. They have not been widely described in the Patagonian Andes of southern South America and here we provide the ...

Assessment of rock glaciers and their water storage in Guokalariju, Tibetan Plateau [PDF]

open access: yesThe Cryosphere
Rock glaciers are important hydrological reserves in arid and semi-arid regions. Their activity states can indicate the existence of permafrost. To help further explore the development mechanisms of rock glaciers in semi-arid and humid transition regions,

ROCK GLACIERS IN THE KOLYMA HIGHLAND

open access: yesЛëд и снег, 2015
Based on remote mapping and field studies inGrand Rapids, Tumansky,Hasynsky,Del-Urechen Ridges as well as Dukchinsky and Kilgansky Mountain Massifs there were identified about 1160 landforms which morphologically are similar to the rock glaciers or they ...

Rock glaciers in the Suntar‑Khayata Range

open access: yesЛëд и снег, 2016
The remote map‑making technique and results of field investigations made possible for the first time to reveal a great number of rock glaciers within the area of the Suntar‑Khayata Range (North‑East Asia). A total of 540 formations were identified. Among

Éboulis et glaciers rocheux(Talus and rock-glaciers)

open access: yesBulletin de l'Association de géographes français, 1983
On examine les relations spatiales, temporelles et génétiques entre les éboulis ou formations de pente à blocailles structurées et les glaciers rocheux, ainsi que la signification paléoclimatique et paléomorphologique de l'environnement des glaciers rocheux hérités.

On the dynamics of rock glaciers [PDF]

open access: yes, 2020
Mountain permafrost is currently enduring substantial modifications due to climate change. A drastic increase in the creep rates of rock glaciers and the onset of rock glacier destabilization have been observed at the regional scale since the 1990s, concurrent with ground temperatures warming and widespread ice loss.
