A note on needle-ice mound formation in the High Drakensberg, Southern Africa
Afrique du Sud ; Butte ; Cryoturbation ; Drakensberg ; Erosion ; Glace ; Montagne ; Périglaciaire ; Transport sédimentaire ; Trentino-Alto Adige
This note describes small episodically-forming ice mounds in the High Drakensberg that are similar to bugors and which develop within restricted topographical and climatological settings. These mounds contribute towards turf exfoliation, thereby
Annually re-forming miniature sorted patterned ground in the high Drakensberg, Southern Africa

Drakensberg. Although the sorted patterns in the high Drakensberg are somewhat polygenetic in developmental origin, they are primarily frost-induced. The development of miniature sorted patterns within 5 to 6 weeks demonstrates the effect of regular freeze
-thaw cycles at higher altitudes in the Drakensberg.
The role of moisture in the weathering of the Clarens formation of the KwaZulu-Natal Drakensberg : implications for the preservation of indigenous rock art
The Clarens Formation in the KwaZulu-Natal Drakensberg, South Africa, contains some of the world's finest rock art. This heritage is fast disappearing as a result of natural weathering processes. Investigations are focused on the development
This study focuses on rainfall, air temperature and soil temperature measurements recorded at 2 field stations on the Lesotho-Drakensberg escarpment edge. Temperatures confirm the marginal periglacial nature as postulated for previously
Towards an integrated research approach for the Drakensberg and Lesotho mountain environments : a case study from the Sani Plateau region

The Drakensberg, adjoining the eastern Lesotho highlands, have been proclaimed as South Africa's fourth World Heritage Site. The objective of the paper is to demonstrate the potential value of intra-disciplinary and problem-orientated geographical
This paper presents empirical data on non-sorted patterned ground in the high Drakensberg. Some morphological and sedimentary characteristics for thufur and non-sorted steps are provided. The study also examines process data on ground heave activity
Block and debris deposits in the high Drakensberg, Lesotho, Southern Africa : implications for high altitude slope processes
Afrique du Sud ; Coulée boueuse ; Drakensberg ; Dynamique de versant ; Dépôt de pente ; Glacier rocheux ; Lesotho ; Montagne ; Paléo-environnement ; Périglaciaire ; Quaternaire ; Solifluxion ; Variation climatique
This study describes the morphology and discusses the likely palaeogeomorphic processes of blockstreams and debris deposits on the Popple Peak and Njesuthi-Mafadi south-facing slopes in the Drakensberg. The geomorphic evidence provides much needed
information to help improve the understanding of south-facing slope processes during past colder periods. A model for high altitude Drakensberg south-facing slopes is presented and used to challenge and expand on recent models and ideas on southern African

Valley asymmetry on south-eastern Alexander Island, Antarctica, and valley forms in the High Drakensberg, Southern Africa
Field data from Alexander Island, Antarctica, are used to develop a model for the formation of asymmetrical valley-side slopes. The application of the model to high altitude valley slopes formed in the Pleistocene in the Drakensberg is considered
Protalus ramparts and the altitude of the local equilibrium line during the last glacial stage in Bokspruit, East Cape Drakensberg, South Africa
A ridge of unconsolidated debris at an altitude of 2000 m, located beneath cliffs in the East Cape Drakensberg of South Africa, is interpreted on morphological and sedimentological evidence as a protalus rampart. The rampart is believed to have
Terracettes and active gelifluction terraces in the Drakensberg of the Province of the Eastern Cape, South Africa. A process study
Terracettes and turf-banked terraces exist at Tiffindell Ski Resort in the Drakensberg of the Eastern Cape at altitudes between 2750 m and 2880 m on slopes of between 15° and 26°. The terraces move downslope under the influence of gelifluction
Institutional impediments to the implementation of the Maloti Drakensberg Transfrontier Conservation and Development Project : the case of the Free State government
The paper focuses on tourism development in the Free State, and the role of the provincial government in hampering it. In particular the investigation examines the development of the Maloti Drakensberg Transfrontier Conservation and Development

Intra-storm attributes of extreme storm events in the Drakensberg, South Africa
Intra-storm rainfall attributes were analyzed for 49 extreme storm events at 5 locations in the KwaZulu-Natal Drakensberg. Three stations located in the mountain foothills and two stations sited on the escarpment edge above 2800 m a.s.l. provide
the first detailed intra-storm data for the Drakensberg. Extreme rainfall events were found to vary in duration and in depth, but all stations measure a clear exponential distribution of cumulative kinetic energy content of storm rainfall over time. Further
