Organ Pipes — Dolerite Column Formation, Twyfelfontein

A few kilometres from the Twyfelfontein rock engravings, the Organ Pipes are one of Damaraland’s most dramatic geological features: a ravine filled with vertical dolerite columns up to 5 metres tall, formed by volcanic intrusion and erosion approximately 120 million years ago. The parallel columns resemble the pipes of a church organ and create an otherworldly corridor through the rock. Free to visit; best light in the late afternoon.
