On
route to the observatory, one will find Salpeterkop, the last
active volcano south of the Equator some 66 milion years ago.
It lies at a height of 1767 metres above sea level. An intensive
study was made by the University of Cape town in the early 1970.
They found traces of 77 minerals and only one - Barite - was worth
exploring.
Seismographically the Japanese found out that Sutherland and the
surrounding area are the quietest in the world!!
