Title: | Thufur in the Mohlesi valley, Lesotho, southern Africa / S.W. Grab. |
Author(s): | Grab, S. W. |
Date: | 1994. |
In: | Permafrost and Periglacial Processes. (1994.), Vol. 5(1) (1994) |
Abstract: | Field observations and measurements provide empirical information on external and internal morphology in this alpine region. Animal activity, wind action, effects of surface water and/or ice, and influence of needle ice are factors which cause breakup of thufur. Some thufur in this valley are periodically active under present climatic conditions. |
Notes: | Permafrost and Periglacial Processes. Vol. 5(1) :111-118 (1994). |
Keywords: | 551.34 -- Geocryology. Frozen ground. 551.343.72 -- Frost mounds. Pingos. E8 -- Glaciology: frost action and permafrost. (68) -- States and territories of southern Africa. |
