I acknowledge and pay respect to the actions, sacrifice, wisdom, traditions and curiosity of our ancestors. Their collective efforts over centuries helped evolve our western civilisation, giving birth to the liberal society that makes this work possible.
Mark,
Congratulations on your fight to keep places like Mount Warning open to all.
I wish Ayer’s Rock was still the same
Love to talk of how I can help
Is you mobile the best

Marc. I am distraught and angry. Mt Warning closed. Ayer’s Rock closed. Talk of Tibrogargan, Beerwah closures. Land at Burrum Heads declared off limits. What’s next? Fraser? Moreton? Bluff Knoll? What can I do to help support this cause?

There’s a large group climbing tibro on Saturday if you are close.. join in. The Mt Warning Fbook group re-open Mt warning, and also FB page “oh the places you can’t go” worthwhile. Writing letters to the NSW environment Minister perhaps a little futile but a good way to vent frustration. Send also to QLD environment. There are plans for a protest meeting in Murwillumbah in September – keep an eye on that FB page for details. regards Marc

I am intending climbing mount Warning in the next few months and will bring a few friends. Prepared to take it all to court.

Mark:
Excellent work on the Nepal avalanche/debris flow. I was wondering if you have ever seen your multi-phase approach and volumetric analysis applied to the 1970 Yungay Peru avalanche/debris flow? After visiting there in the 80’s I felt that there was a real debate regarding the multiplier/entrainment factor. I’ve never seen an analysis or estimate of the ice:rock ratio of the initial slide but everyone seemed to assume it was mostly ice not rock. A second look at Yungay might suggest an initial slide that was mostly rock that flash melted the glacier below.
Curious whether you thought of any parallels between Yungay ‘70 and Nepal 2026?
