Swartberg

The Swartberg mountains (black mountain in English) are a mountain range in the Western Cape province of South Africa. It is composed of two main mountain chains running roughly east–west along the northern edge of the semi-arid Little Karoo. To the north of the range lies the other large semi-arid area in South Africa, the Great Karoo. Most of the Swartberg Mountains are above 2000 m high, making them the tallest mountains in the Western Cape. It is also one of the longest, spanning some 230 km from south of Laingsburg in the west to between Willowmore and Uniondale in the east. Geologically, these mountains are part of the Cape Fold Belt.

Much of the Swartberg is part of a UNESCO World Heritage Site.[citation needed]

The Swartberg consists of two officially named ranges, the Smaller and the Greater Swartberg Mountains.

The Smaller Swartberg are the westernmost of the two. Ironically, this range is the higher one, including the province's highest peak, Seweweekspoortpiek (Seven Weeks Gorge Peak) at 2325 m. The famous Towerkop (Bewitch Peak) towers over the Klein Karoo town of Ladismith at a height of 2189 m. The peak is so named for its cleft peak, that, according to legend, was split by a spell and subsequent bolt of lightning.

The Greater Swartberg is located to the east, with the dividing line between the two ranges being the Gamka River, which cuts a gorge directly through the range. This section, almost of a similar height, is slightly lower in elevation, with the Tierberg (Leopard Mountain) at 2132 m being the highest. These mountains are home to the Cango Caves in the exposed limestone basement rocks exposed by upliftment along a 300 km fault line that runs along the southern flank of the Swartberg ranges (see diagram on the left). These are the most famous subterranean system in South Africa, located just north of Oudtshoorn.

Several passes cut through the Swartberg Range, and these are famous primarily for the spectacular geology they dissect, as well as for the engineering skill required in completing several of the routes across them.

Until the first pass was cut, these mountains were virtually insurmountable, and cut the Great Karoo off from the Little Karoo and from the coast. John Molteno, Beaufort West businessman (and later Prime Minister) first surveyed the range for a pass with Andrew Bain, Thomas Bain. They rode out from Beaufort West on horseback, in 1854, for a week-long ride to traverse the range and plan the routes.

The pass was cut and the route completed in only 223 working days, comprising one of the era's most extraordinary feats of engineering. It was also a huge economic step for the interior of the Cape Colony. For example, by 1870, an eighth of the country's wool exports passed through the Meiringspoort.
