Stephan Thaele once again showing his mastery of iPhone movie making in the field while actively teaching and participating on an expedition!
In response to the recent press about the possibility of a cableway being built on Mt Kilimanjaro, I was recently interviewed by Pippa Hudson on CapeTalk/Radio702. Her questions focused on the basics of altitude illness, and some reflection on what the medical risks of a cableway would entail. You can read the MCSA/UIAA statement on the proposed cableway here.
You can listen to the radio interview below, or if that fails at one of the links.

One of our expedition participants, Dr Stephan Thaele, produced this amazing video along the way by working a little on it each day on his phone as the expedition unfolded. What a great source of memories!
Oliver Page, one of our enthusiastic course participants made this short video of his experience on our WildMedix Canyoneering Medicine course in February this year. Check it out and give him some love!
Labour of love and quite a few years work: my mother Robynn and I have written a guide “by divers for divers” to the dive resorts of Mozambique. This was more of a challenge than anticipated, as the sociopolitical climate in Mozambique means that there is a continually shifting landscape when it comes to dive operators, and some significant regional differences. Although there are some very well established resorts and operators, many of the smaller, newer or more exclusive venues are unknown, and no-one could give an accurate estimate of the actual number.
The book has been thoroughly researched but is filled with actual impressions and practical reviews of the many resorts, and is worth acquiring simply for the hundreds of original photographs from a plethora of contributors.
It is available from September 2017 from various online vendors, and SA bookstores. Click here to go to the publisher’s site to purchase a copy.
I’ve created a fixed page for this presentation and the reference materials, so that I can add to the thoughts and resources over time. You can access the permanent page with all the references here.

Having spent many years enjoying the wilderness across 6 continents (hold on Oceania, I’m coming), including wintering over in Antarctica and years of service in mountain rescue, and then gaining the perspective afforded to me by having my own serious wilderness accident, I am very mindful of how we balance the risks and rewards of wilderness adventures. Greg Hill captures the essence of some very simple but powerful advice for staying safe in this brief video. Watch and reflect!
Transcribed here in my words:
Greg Hill’s 5 Rules for Staying Safe in the Wilderness
- Be afraid – be aware of the risks, and cognitive of the risks.
- Be prepared – get educated, find mentors, be guided, get good equipment, take the courses, develop your own mountain sense.
- Have a great team – find good partners.
- Have a plan – prepare for eventualities, have an escape route
- Be vigilant – maintain situational awareness, reassess plans fluidly.
Actually, that sounds like a good set of 5 rules for prehospital emergency medicine, anaesthesia, or any other high-stakes game!
