Otago Harbour Lookout – Buy
It’s hard to comprehend just how long ago 13 to 16 millions years really is. That’s a mind boggling length of time. I mention this because that’s how long it’s been since the Otago Harbour was active as a volcano. The highest point of the extinct volcano was around 1000m with the area between Port Chalmers and Portobello being the vent while the surrounding hills Mt Cargill, Flagstaff, Saddle Hill, Signal Hill and Harbour Cone are remnants of the volcanic crater. Then, over the next 11 million years the volcanic mountain was shaped by extensive erosion and fault activity, into valleys and hills that included the forming of harbour which was eventually filled in by the sea.
