Salpeterkop (Saltpetre Hill) was an active volcano around 66 million years ago – estimated as the last one in Southern Africa. It is interesting to note that about 2 km of of its original height has been eroded down, so we are seeing at a level 'deep in the throat of the volcano'. The remains of this volcano is visible from the SALT (South African Large Telescope) site near sutherland.

Salpeterkop (Saltpetre Hill) was an active surface volcano about 66 million years ago – believed to be the last one in South Africa, making it the youngest known active volcano in Africa south of the Equator.

Its present summit is reached via a kilometre-wide lava ash field.*

'My first three years, I was working with other people as I was undergoing training. From there on, most of the time I was on my own.
