Exploring the Organ Pipes on Mt Cargill
Located near Dunedin, the Organ Pipes are a fascinating rock formation on the path leading to the summit of Mt Cargill, which stands at 676 metres. This natural wonder is a must-see for those interested in geology or seeking a unique hiking experience. The Organ Pipes can be accessed from several points, but the most direct route begins halfway up Mt Cargill Road, above Port Chalmers.
Discovering the Organ Pipes
As you approach the Organ Pipes, you'll first encounter what appears to be a steep pile of tube-like rubble. These are sections of the pipes that have eroded and collapsed over time. Despite their appearance, the pile is stable, and a short scramble will lead you to the top, where the pipes remain intact. From this vantage point, you can enjoy breathtaking views of the surrounding landscape.
Continuing to Mt Cargill Summit
If you're up for more adventure, continue your hike from the Organ Pipes for another 20 minutes to reach the summit of Mt Cargill. The additional climb rewards you with expansive views and a sense of accomplishment.
Ancient Volcanic Origins
Mt Cargill and the Organ Pipes are remnants of the ancient Dunedin Volcano, a massive shield volcano that was active between 16 and 10 million years ago. This extinct volcano originally extended from modern-day Dunedin to Aramoana, standing approximately 1,000 metres high. Over the last 10 million years, extensive erosion has carved away much of the volcano, and Otago Harbour now fills its oldest central crater. The hills surrounding the harbour, including Mt Cargill, Flagstaff, Signal Hill, and the Otago Peninsula, are all that remain of this once-mighty volcano. The Organ Pipes themselves are striking examples of columnar basalt, formed when lava flows cooled and contracted, creating the distinctive vertical columns visible today.
