Tsumeb is the home of the world-famous Tsumeb mine, and the "gateway to the north" of Namibia. It is the closest town to the Etosha National Park.
Near to the town are the large and famous sinkhole lake, Lake Otjikoto. The depth of the lake are unknown, because towards the end the lake disappear into lateral cave systems. Divers who have performed bounce-dives in Otjikoto (strictly speaking, beyond the safe depth for SCUBA dives, especially given the altitude of the lake above sealevel) have reported that there was lots of different guns and ammunition.
This was dumped by German forces in early years. Otjikoto has been in existence for so long that a unique species of fish, Otjikoto Tilapia, has evolved in its waters. Tsumeb is generally pronounced "SOO-meb". The name is not a derivative of German, Afrikaans, or English. It has been suggested that it comes from Nama and means either "Place of the moss" or "Place of the frog".
