Their curiosity piqued by their previous re-enactment "A Most Ambitious Journey" Gurney and Moffatt were motivated to re-trace the steps of Marmaduke Dixon and Guy Mannering; in a most exciting mountaineering / kayaking dual adventure.
Dixon and Mannering in 1890 were attempting to be the first to summit Aoraki/Mt Cook, followed by paddling their Rob Roy kayaks from the Hermitage down to the east Coast at Oamaru. Once again, Gurney was like a kid in a toyshop using the most modern equipment he could, whilst for comparison Moffatt uses gear and food of the original adventurers; hobnail boots, tweed jacket, oilskins, etc.
The trip didn't go as planned with a drama high on the flanks of Aoraki/Mt Cook, with consequences later in the trip.
The learning the pair got from this has direct applications, not only to modern-day adventure, but in Gurney's opinion, to the rapid march of technology in every-day modern life. Gurney expands on this concept in his latest book "Eating Dirt" and as a conference speaker.
