“Paths of the Dead” comes to mind when you see the Putangirua Pinnacles. These impressive rock formations are one of New Zealand’s best examples of badlands erosion. The Putangirua Pinnacles have fascinated locals since time immemorial.
Welcome to the Putangirua Pinnacles. We will explore the unique geological formations that make this place so special. The Putangirua Pinnacles are earth pillars or hoodoos. They are located in the Aorangi Ranges on the North Island.
Let’s step back millions of years. Seven to nine million years ago, sea levels were much higher. The Aorangi Ranges were an island. Over time, erosion shaped this landmass and large alluvial fans formed on its southern shores.
Then, sea levels rose again, submerging the island. Since the ice ages, the sea levels have receded. The old alluvial fans were exposed to wind and water. These forces weathered away at the conglomerate.
In some places, cemented silt or rock protected the conglomerate. This resulted in the formation of these spectacular Putangirua Pinnacles. Rainwater runs down their sides during major storms, creating prominent fluting.
Geologists estimate that the Putangirua Pinnacles started forming less than 125000 years ago. Major erosion likely began 7000 years ago. It accelerated in the last 1000 years due to deforestation. Today, the erosion rate is approximately 1 cm per year.
Did you know that the Putangirua Pinnacles have appeared on the big screen? Part of “The Lord of the Rings: The Return of the King” was filmed here. The Paths of the Dead sequence featured these impressive formations. The opening sequence of “Braindead” was also filmed here.
Imagine Aragorn, Legolas, and Gimli walking among these pillars. They were on their way to meet the Dead Men of Dunharrow. The looming pillars added to the scene’s eerie atmosphere.
The Putangirua Pinnacles offer several walking tracks. These range from short, easy strolls to longer hikes. Sturdy shoes are recommended. Keep an eye out for falling rocks, especially after heavy rain.
For a longer walk, head uphill from the lookout. You will have excellent views over Palliser Bay and Lake Onoke.
These formations are an amazing collection of hoodoos. They have long vertical ridges caused by rainwater. The effect is like separate stone rods grouped together.
So, as you stand here among these ancient formations, consider the power of nature. The Putangirua Pinnacles are a testament to the forces that shape our world. They will leave a lasting impression on all who visit.
