The periglaciallandforms of the Giant Mts. has been recognized in the most elevated part. The presented hypothesis of landscape evolution calls for detailed geomorphological research. - (MS)
, is not the case in the Pohorje Mountains : built of igneous and metamorphic rocks, it was not glaciated due to its insufficient elevation, but was subject to periglacial processes. In the article, some of the periglaciallandforms of the Pohorje mountains
Contrary to the well-studied Pleistocene glaciation, periglacial phenomena in Slovenia have been given less scientific attention because they are not particularly evident in high mountains due to prevailing carbonate rocks. This, however
Periglaciallandforms of Southern Africa compared with those of Colorado and New Mexico

Periglaciallandforms in southern Africa and the alpine zone of Colorado and New Mexico are compared. Lower altitudinal features in southern Africa reflect a drier environment. - (AJC)
The significance of periglacial phenomena in Iceland
This paper gives a systematic survey of the periglaciallandforms of Iceland. The presentation is centered on the question of the significance of distinct periglacial features on certain climatic and edaphic environmental conditions
, and on the question of the place which the volcanic island of Iceland holds within the periglacial zone. (l'A.).

, particularly on a physical basis; 3) on the relationship between processes and landforms; 3) on the information value of fossil periglaciallandforms on paleo-climatic reconstructions and 4) on the prediction of future developments in periglacial areas
This paper suggests that the main task of periglacial geomorphology : remains that of developing a better knowledge of existing periglacial geosystems. This includes and intensified research on a sequence of four topics : 1) on periglacial processes
Late Weichselian Periglaciallandforms in the Bergsted area, north-western Zealand, Denmark
Dating ; Denmark ; Geographical information system ; Ice wedge ; Model ; Nivation hollow ; Periglacial features ; Thermoluminescence ; Wind erosion
This paper presents various Late Weichselian periglaciallandforms which have been identified in the Bjergsted area. The investigation of the periglaciallandforms is an important step in the development of a comprehensive deglaciation model
Dynamics of glacial and periglacial processes as evidence of global change
Freeze-thaw cycle ; Glacial activity ; Glacial features ; Glacial landform ; Global change ; Periglacial features ; Quaternary
Glacial and periglacial processes, their landforms, influences of cryogenic destruction, and repeated freezing and thawing effects in rocks and their weathered mantle are described. Main features and dynamics of present-day and former glacial
and periglacial environments are presented as an evidence of significant global change of various landscapes in the Quaternary epoch. Knowledge of glacial and periglacial processes and landforms provides a background for understanding the present-day global change
An analysis of rock landforms in the NW part of the Hostýn Hills. Periglacial and land forms are formed in the Pleistocene and in the Holocene, in the relationship among rock landforms, geological and climate conditions in the Rusavská hornatina Mts
A pleisztocén periglacialis domborzatatformalas Magyarorszagon. (Periglacial sculpturing of relief in Hungary in the Pleistocene)
In the study the most typical Pleistocene periglacial processes, forms and deposits are presented. The final conclusion is that the relief of Hungary was heavily reshaped under periglacial climate and the landforms still preserve much
of their periglacial character. The trend of relief evolution was towards planation in the Pleistocene. (DLO).
Glacial history and periglaciallandforms of the Zackenberg area, Northeast Greenland: preliminary results

on the use of a multi-model photogrammetric method, has been the basis for a GIS database and a topographical map (1:50,000), covering the investigation area. Both glacial and periglaciallandforms have been maped and a preliminary Late Weichselian glacial
Periglacial slope deposits and landforms in a Hungarian mountain of volcanic origin in Environmental and dynamic geomorphology.
The early Pleistocene development of an almost 2 km long slope is reconstructed in the Tokaj Mountains, NE-Hungary. The variety of periglacial forms and geomorphic processes are described for the four distinct segments of the slope. (DLO).
Remnant periglacial features on the summit of Truskmore, Counties Sligo and Leitrim, Ireland in Periglacial processes and landforms.
The features include sorted nets, a possible cryoplanation terrace and stone-banked terraces. The remnant periglacial forms owe their existence to a resistant cap of sandstone on the plateau surface which has weathered to form a frost susceptible

The glacial and periglacial geomorphology for the Simen and Bale Mountains in Ethiopia is reviewed. The Simen Mountains are mostly absent of relict perglacial landforms and today host a variety of miniature cryogenic phenomena. The Bale Mountains
host a few localized large relict cryogenic landforms (e.g. stone stripes), suggesting past sporadic permafrost. A variety of regional factors may have contributed to the more extensive periglacial activity in southern Ethiopia than in the higher Simen

A brief historical overview of research outputs and approaches is presented for the respective African regions. Potential future quantitative periglacial research needs and approaches identified for Africa include : the examination of active
Upper slope landforms and age of bedrock exposures in the St. Francois Mountains, Missouri : a comparison to relict periglacial features in the Appalachian Plateau of West Virginia

The AA. observed upper slope landforms in the St. Francois Mountains of Missouri and compared them to relict periglaciallandforms in the Appalachian Plateau of West Virginia in order to determine if periglacial conditions existed in southeastern
