Sossusvlei, formed by the Tsauchab River, is a world-renowned destination attracting thousands of tourists a year. And the allure of this famous draw card surrounded by wind-sculpted red dunes continues to grow, attracting visitors from all over the world.
M any thousands of years ago, during periods of high rainfall, the powerful Tsauchab River, rising in the Naukluft and Zaris mountains, carved a meandering route through the earth’s crust to pour its silt-and sand-laden waters into the cold Atlantic Ocean. The river debouched into the sea between Meob Bay and Conception Bay, and nothing could stop its scouring floodwaters, the Sesriem canyon being evidence of its once powerful flow.
This defiant act by the Tsauchab and other mighty rivers led to the demise of several of them as the sand deposited into the ocean, eventually formed the dune barriers, blocking their access to the sea. Water from these rivers still flows under the sand from the high-lying interior to the coast. Explorers and diamond miners utilised these sources of fresh water where they appeared above ground, close to the ocean. Today the Tsauchab River appears to end at Sossusvlei. Other ephemeral rivers include the Koichab east of Lüderitz and now the main water source for the town. Where it ends at Tsondabvlei, the Tsondab River, rising south-east of the Naukluft Mountains, is surrounded by dunes.
Early explorers, prospectors and hunters in Namibia used ephemeral rivers like the Tsauchab, Hoarusib, Hoanib and others to penetrate deep into unknown territory, as they offered relatively easy access and vitally important sources of water in arid desert areas. The alternative for pioneers and explorers was to travel into unknown territory after good rains. Streams, waterholes and hollow rocks held water fro some time and the hardy adventurers utilised these temporary sources.
In early 2011, copious rains fell over most of Namibia, which would have made it a good year for explorers venturing into unknown territory, had there been any more such areas to explore. However, a hundred years ago the young German colony of Deutsch Südwestafrika was mostly a blank map to the new colonists. One of them, Lieutenant Walter Trenk of the Schutztruppe (the German colonial troops in the country) seized the opportunity to explore after the good rains in 1909. In February of that year, leading a patrol of 15 mounted troopers, he set off to explore the area known as Sossus, at the end of the Tsauchab River. For military purposes, a reconnaissance patrol was deployed to establish what was at Sossus. Further motivation to explore the surroundings were rumours of a legendary Bushman Paradise, although no one could say where or what it was.
The patrol left Sesriem early, following the river. Trenk describes the narrow course with its high, rocky banks eventually widening as they rode down its twists and turns. Huge camelthorn trees lined the banks. Many miles further, as the first high dunes began encroaching from the north, he noted that the river was heading directly westwards in a wide valley. Besides the many camelthorn trees along the river, he also noted the dead trees about 35 kilometres from Sesriem. These dead camelthorn trees are still visible when travelling to Sossusvlei, just north of the present road. With the reduction in water flow as the area became drier and drier, the river no longer pushed its life-giving waters so far onto the plain, and the young trees died from lack of water. Their remains have not disappeared, as the arid conditions are unfavourable for bacteria and the dry wood will take many hundreds of years to decompose and disappear. Dead Pan, named for the stark skeletons of camelthorn trees that sporadically punctuate its cracked white clay floor, has been host to these graphic ghosts for over 500 years and will probably present the same eerie scenario for another few centuries.
Trenk and his troopers found pools in the river, which provided much-needed sustenance to their horses. On the evening of 11 February, they camped in the Tsauchab riverbed, waiting for the moon to rise before continuing their journey during the cool night hours. The horses were grazing when animals, possibly hyaenas, frightened them and they took off. Although the men looked for their scattered mounts by moonlight, they could only continue their journey later the next morning after walking a long way to find them. Trenk reports seeing gemsbok and ostrich, but makes no mention of springbok. The trees became fewer as they rode down the river, eventually disappearing altogether.
On the evening of 12 February, they reached a thick stand of trees, most likely a little north of the present 2×4 car park. After crossing some low dunes, Trenk and his patrol reached the end of the Tsauchab River valley, finding big camelthorn trees and many !nara bushes. The !nara is a remarkable desert-adapted plant that has no leaves but produces an abundance of melon-sized fruits that are an essential source of food and liquid for many desert-dwelling animals. Gemsbok, springbok, jackal, hyaena, rodents and birds depend on the !nara to survive in the harsh desert environment. On several !nara plants Trenk noted ostrich wings put over the fruit, which he assumed had been placed there by local people, possibly the San/Bushmen, to act as scarecrows to keep animals away from the moist, nutritious fruits with their sweet yellow juice, which they possibly used as a substitute for water.
The troopers inspected the area, but found no signs of water, or of the reputed Bushman Paradise. Despite the pools in the river, the floodwaters had not been sufficient to reach the pan at Sossusvlei. Because of the lack of water and grazing for their horses, they left at midnight and rode back to Sesriem. In his official report, accompanied by a map and published in the Deutsches Kolonialblatt 1910 (Volume 20, No 17), Trenk notes that at Sossusvlei the Tsauchab River disappears into the dunes. He may have been the first white man to see the place now known as Sossusvlei. Certainly, his was the first recorded visit to this now world-famous tourist draw card surrounded by the towering red dunes of the Namib Desert.
