Mount Thirsk

Mt. Thirsk boasts over 300 m prominence above the saddle with Robertson Peak and is rugged and bluffy on all sides. This one sees far less visitor than the bigger neighbour. Even Robertson Peak was once an obscured objective, but the situation had taken a sharp turn since I climbed it back in 2021. There were only 4 known ascents prior to that trip but as for 2026 there are already over 20 people logging it in even just on peakbagger.com. Mt. Thirsk has no “beta” whatsoever but bivouac.com casually mentioned it could have seen an ascent by the surveyors’ party decades ago. There was no account of the said ascent, so this could still potentially be a virgin peak. This triggered my curiosity for years but I couldn’t figure out an obvious route. I had proposed three different options and all three of them had some major uncertainties that I wasn’t too keen to tackle without being pushed by someone else more keen on venturing into the unknowns than myself. This person turned out to be Francis Bailey.
