Cogmans Kloof Road (between Ashton and Montagu)

Kogmans (or Cogmans) Kloof is a Gorge through the Langeberg between Ashton and Montagu on the R62 to Oudtshoorn. It is named after the Cogmans, a Khoi chiefdom that existed in the Area around the beginning of the 18th Century.

The Pass was constructed by Thomas Bain from 1873 - 1877 and follows the course of the Kingna River, which flows South West of Montagu.

The History: Work on the road began in 1862, but was suspended in 1869 due to labour issues. It was only in 1873 that Thomas Bain finally took over and completed the Pass in 1877. It was also during this period that Thomas built the Tunnel through Kalkoenkranz, one of his more challenging endeavors. In 1931 the Road was tarred, but a new road built in 1953, left Hodges Bridge no longer in use. Now in 2021 and before that there have been tremendous changes on the Road from Ashton to Montagu. Kogmanskloof Gorge is almost entirely incised within intensely folded sandstone of the Table Mountain group (TMG). At the Southern (Ashton) end of Kogmanskloof the Malmesbury group underlies these younger folded sandstones that dominate the scenery of the Kloof. The formations in Kogmanskloof were deposited, folded and faulted over 500 Million Years ago. The most striking feature of Cogmanskloof is the way it cuts through the mountain range. It is one of several such features found in the Cape Mountain Ranges, perhaps the best known being the Seven Weeks Poort which slices through the great Swartberg Range near Ladysmith to the East.

Exactly which processes acted to form these features are unknown, but several mechanisms probably worked together to produce them. The Rivers may well have existed prior to uplift of the Mountain Range and their erosional power was able to keep pace with the rise of the land, that is, they could cut down as fast, or faster, than the rate of uplift. Thus, there may have been a super positioning of streams onto the folded Mountain Range from some earlier elevated landscape. The geomorphology of the Kloof today is in a sense unique because it is undergoing continuous modification. Although in any single lifetime, little or no change may be apparent, over a long period of say, millions of Years, many aspects of the Kloof morphology would have changed. A reminder of the powerful forces of erosion was provided in January 1981, when heavy rains in the Southern Karoo caused the Keisie and Kingna Rivers to flood and meet at their confluence in Montagu, before rushing through Cogmanskloof to Ashton and the Breede River, with considerable loss of life and damage to property. The road is to be raised and realigned to minimize flood damage in years to come.

Obituary: Eddie Webster’s influence over generations of students extended to the country and beyond its borders by Andries Bezuidenhout (Mail and Guardian), 6 March 2024

Professor Edward Charles Webster — or Eddie, as he was known to his family, friends and colleagues — unexpectedly died of a heart attack on Tuesday. He was 81 years old, but about two years ago, he led an eight-hour hike in the Amatole Mountains near Hogsback as part of his 80th birthday celebrations. Eddie jogged, swam and regularly played squash. He was also active on Twitter (or X, I guess), where his handle was “Sociology Madala”.
