“…The main evidence tends to be from geophysical investigations (e.g. Barsch, 1973;Fisch et al, 1977;Haeberli, 1985;Barsch and King, 1989;Evin and Fabre, 1990) and drilling operations (Barsch et al, 1979;Vonder Mühll and Haeberli, 1990) and does seem to show the presence of interstitial ice (ice-cemented) rather than an ice-core in many modern rock glaciers. Morris and Olyphant (1990) suggest that ice-cemented rock glaciers form when conditions are sufficiently cold and wet to produce an ice matrix within rockfall debris but insufficient to promote positive mass balance.…”

“…It is also generally accepted that in some contexts both kinds of ice can be present in rock glaciers, as noted earlier where ice-cored rock glaciers can form by the periglacial deformation of recently deglaciated ice-cored moraines. However, it is important to appreciate that measurements and observations show that permafrost is always associated with rock glaciers (Evin and Fabre, 1990).…”

Relict rock glaciers have been identified and mapped in the high cirques of Mount Tymphi, in the Pindus mountains of northwest Greece. They are periglacial forms and represent the most recent cold-stage landforms in an area that displays widespread evidence of Pleistocene glaciation. It is likely that these features formed during the Last Glacial Maximum (Late Würmian) as talus rock glaciers, and beneath small cirque glaciers as debris rock glaciers. Comparisons with modern rock glacier-climate relationships suggests mean annual temperatures of ca. 8-9°C lower than present at their time of formation. This temperature reconstruction is in good agreement with recent palaeoclimatic reconstructions for the northern Mediterranean based on a general circulation model. Moreover, as rock glaciers are typical of cold and relatively dry mountain regions, their presence is consistent with palaeobotanical and lake-level data suggesting a cold and relatively dry climate for the Last Glacial Maximum in Greece. However, the presence of small cirque glaciers above some rock glaciers suggests that although precipitation must have been low enough to preclude glacier extension down to lower altitudes, it was not so low as to inhibit glacier formation entirely.

“…c) Altitud. Este factor es claramente determinante también en la génesis de los glaciares rocosos puesto que es el que impone unas determinadas condiciones climáticas tanto locales como, sobre todo, zonales, a través de un determinado gradiente térmico (Evin & Fabre, 1990). Por eso resulta de sumo interés conocer a partir de que nivel altitudinal, o entre que niveles, se desarrollan estas formas porque ello nos permite una aproximación a las características paleoclimáticas en el caso de los glaciares rocosos fósiles.…”

“…The technique is described by Koefoed (1979), and an excellent field manual has been written by Flathe and Leibold (1976). Its suitability for mountain permafrost areas and its limitations are shown in King (1982King ( , 1986, , King and Seppala (1987), Barsch and King (1989), Evin and Fabre (1990) and Evin (1992).…”

Geomorphologists as well as engineering geologists are increasingly interested in the prediction and mapping of mountain permafrost and associated phenomena. Using several indirect geophysical and geomorphological methods, it is possible to detect and map permafrost that is usually invisible at the surface. This paper summarizes the merits of the most frequently used methods, their difficulties and limitations, and gives recommendations on how to use them. Brief recommendations for future research are also given.
