The Nooitgedacht Glacial Pavements comprise a geological feature between Kimberley and Barkly West, South Africa, pertaining to the Palaeozoic-age Dwyka Ice Age, or Karoo Ice Age, (some 300 million years ago) where the glacially scoured (smoothed and striated) ancient bedrock (re-exposed by erosion) was used, substantially more recently, during the Later Stone Age period in the late Holocene ...
In geomorphology, an outburst flood—a type of megaflood—is a high-magnitude, low-frequency catastrophic flood involving the sudden release of a large quantity of water. [1] [2] During the last deglaciation, numerous glacial lake outburst floods were caused by the collapse of either ice sheets or glaciers that formed the dams of proglacial ...
In this Hubbard Glacier image from 16 July 2002, the glacier has closed off Russell Fjord from Disenchantment Bay. The waters behind the glacier rose 61 feet (19 m) in 10 weeks, creating a short lived Russell Lake. A glacial lake outburst flood is a type of outburst flood occurring when water dammed by a glacier or a moraine is released.
As glaciers melt and pour massive amounts of water into nearby lakes, 15 million people across the globe live under the threat of a sudden and deadly outburst flood, a new study finds. More than ...
Africa, specifically East Africa, has contained glacial regions, possibly as far back as the last glacial maximum 10,000 to 15,000 years ago. Seasonal snow does exist on the highest peaks of East Africa as well as in the Drakensberg Range of South Africa, the Stormberg Mountains, and the Atlas Mountains in Morocco.

Altogether 14 glacial lake outburst floods (GLOFs) [19] occurred between 1935 and 1991. In total, 21 GLOFs [20] have been identified as being potentially dangerous at present. In this way, CC and livelihoods integral part and have vice versa relationship. The low income and subsistence users are about 38% of total population.
