On Friday 4 January 2013, together with Alan Silva, we climbed Mt Dixon, New Zealand’s 23rd highest peak. (Read about that climb here.)
The summit ridge of Mt Dixon is an exposed knife-edge and I wrote at the time:
“I tried not to look down either side at the hundreds of meters of free fall that maybe a base jumper would appreciate however served to intensify my focus on not slipping as we had no protection in.”
The below photo shows Alan Silva climbing the last few steps to the summit of Mt Dixon.
What is important to note in this photo is the rocky/snow-covered ridge line to the top left of Alan’s shoulder. In spectacular fashion, 3 days ago on the 21st January, an enormous chunk of this summit ridge of Mt Dixon fell off. It fell around 500m vertical metres to reach the glacier below, creating a massive landslide which spilled out an incredible 3 horizontal kilometers onto the grand plateau. It narrowly missed Plateau Hut by only 200m (where we spent two nights before and after the Mt Dixon climb).
No one was injured in the landslide, however it must have been a magnificent spectacle to witness at the time. Eye witnesses liken the noise created to “a 747 jet on take-off”. The image below shows the extent of the landslide. The image is courtesy of Alpine Guides. I have added the positions of the summit of Mt Dixon, Plateau Hut, Syme Ridge on Mt Tasman, the Grand Plateau and our route up Mt Dixon. You can see from our route that we chose a very sensible line, well out of harms way!
The below video footage also courtesy of Alpine Guides shows the extent of the volume of rock and debris, and just how close it came to Plateau Hut.
I also attach some links to interesting articles which describe more about the landslide.
Seeing natural events occurring like this is so very humbling. The power of mother nature to unleash thousands of tons of rock from a huge mountain ridge hundreds of meters in the air in an instant and send it crashing down to the valley floor below for kilometers. All I can say is… WOW!!
