Arthur's Pass to Aoraki/Mt Cook - Transalpine Fastpacking

 "Many Canterbury men know that a tough trans-alpine crossing can be a harder test of competence in unorthodox travel and stubborn endurance than a deal of high climbing" - John Pascoe, one of the fore-fathers of early Southern Alps exploration, in Unclimbed New Zealand, 1939.

Starting up the Waimakariri River

The Canterbury Alps sprawling between Arthur's Pass and Aoraki/Mount Cook are just made for trans-alpine trips. While there are great peaks to be climbed in this region - Murchison, Evans & Whitcombe, Malcolm, D'Archaic - the approaches are long and mundane. In my mind, the best way to enjoy these mountains is a traverse. Pick a line that slices through the golden upper headwaters, crossing the high alpine passes between each of the major catchments. You are the artist of your adventure.

Mountaineering can sometimes become obsessed with summits. Transalpine trips on the other hand embrace the core of what mountaineering is about – being and moving in mountains. A transalpine trip that completely avoids any summit and instead weaves an aesthetic line through them makes a statement that achieving a summit is not always the point of being there.

Now that our goal is about movement rather than conquest, how can we maximise our enjoyment of that movement? For me that is finding the lightest way to thread through the mountains. This has led me to explore different gear and strategies to move as lightly as possible.

Fastpacking is the name given to that hybrid activity of trail running and tramping. It's popular in America and Europe owing to well-developed trail infrastructure, and is slowly taking off in NZ, particularly along the Te Araroa trail.

Why not apply this style to transalpine travel in the Southern Alps? Since transalpine trips generally involve simple alpine terrain, some compromises in equipment can be made. Running shoes instead of boots, aluminium crampons and a light axe, ten metres of cord with sling harnesses and a 13L pack to ensure nothing excess is brought along. Trailpinism. Extending this setup to multi-day traverses is the logical progression.

But first, we must look back to the past to understand how to move forwards.

Early Expeditions

Grant Hunter in his book 'Who Was First?' recounts that the first to explore the Southern Alps were the Maori, in the search of a trading route for pounamu. Then came the European surveyors in search of the best pass for a road (Arthur's Pass) in the mid-late 1800s. Recreational trips didn't come until later, as clearly a lengthwise traverse served no purpose in the age of development.

The first recorded trip from the Waimakariri to the Tasman was in Christmas 1934 by Canterbury Mountaineering Club (CMC) members Burns & Townsend. In their account, they acknowledged man's innate desire to walk long distances even as fast land transport was just taking off, and they heeded to a prophesy given by the very first 1932 edition of the Canterbury Mountaineer: "Perhaps in future years a club party will set their time and patience in a trip over the ranges between Arthur's Pass and the Tasman Glacier".

So the concept of Arthur’s Pass to Mount Cook has been a part of CMC lore since the very formation of the club. Back then the Mount Cook village was just known as the Hermitage, after the historic hotel first constructed in 1884, and provides a fitting destination to satisfy one's cravings after a long journey.

The early eras of CMC trips were focused mostly in the local Canterbury Ranges, as unreliable vehicles and rougher roads made for much slower regional travel. Canterbury mountaineers embraced their local mountains and knew their backyard like the back of their hand, without as much distraction of further afield ranges or exotic overseas expeditions. The Coronavirus pandemic now pushes us back to this former time where travel opportunities are limited and combined with climate change we also try to reduce our travel-related carbon emissions. It is here we realise just how much adventure is on offer in our local mountains.

Scrambling around waterfalls in the lower Unknown Stream

The 1934 route taken by Burns & Townsend was entirely in the Canterbury Alps - "the icefalls, jungles and gorges of Westland were left severely alone." Their route crossed the landmarks of Whitehorn Pass, Unknown Col, Ragged Range, Rakaia River, Butler Saddle, Erewhon Station (food drop), Havelock, Forbes, Twilight Col, Godley hut (food drop), Classen, Tasman Saddle, Hermitage. Their trip took 12 days' worth of travelling time. A pretty good effort for the first traverse.

15 years later in 1949, McCabe and Morse decided to up the ante, considering that Burns & Townsend had taken a route quite far from the Main Divide at times, they took a route closer to the higher Alps. Instead of crossing low down in the Ragged Range they took Observation Col at the head of West Mathias. From the Lyell they sidled around McCoy Col, Rangitata Col, down into the Frances, then over Disappointment Saddle, skirting the edges of the Garden of Allah & Eden. Instead of Twilight Col, they took the higher Terra Nova Pass north of D'Archaic into the Godley Glacier, and from there the same route as Burns & Townsend to the Hermitage.

Over the next 50+ years dozens of parties have travelled a similar route to McCabe & Morse, most parties spending about 12-15 days with 1 or 2 food drops along the way.

Modern Traverses

In the last 2 decades, the revered art of gravel-bashing has fallen slightly out of favour, with many more groups opting for detours into the wild West Coast valleys. This trend is perhaps also due to climate change rotting away the glaciers & snowfields of the Canterbury Passes to reveal yet more loose greywacke, and a desire for more remote wilderness travel offered by places like the Mungo, Whitcombe, Bracken, Gardens, Perth and Whataroa. These areas were made considerably more accessible from the 1960s onwards when deer culling huts, tracks and footbridges were established in many Westland valleys. Many of these huts have been adopted and revived by the Permolat 'Remote Huts' group. Detours to these wilderness areas doubles the length of the trip to 25-30+ days, due to slow gorge & bush travel and worse weather.

Folks have then pushed the boat out even further with traverses of the entire Southern Alps, some during tough winter conditions with skis in the mix. A few notable traverses which all of which stuck pretty close to the divide in the Arthur's Pass - Mt Cook section, and were milestones in their own ways are:

                     Graeme Dingle & Jill Tremain's 3 month winter traverse in 1971 - recounted in Dingle's book 'Two Against the Alps'

                     Craig Potton, Robbie Burton, Peter Burton and Paul Roy over the 1980 summer - recounted by Potton in his 2016 book 'So Far, So Good'

                     Steve Bruce and Warren Herrick in 1981 - an epic 5 month traverse entirely on the Western side of the Alps; one of the most accomplished of the traverses ever undertaken

                     Michael Abbot’s 1989-90 solo Southern Alps traverse was also a landmark trip, which broke the solo barrier

                     Richard & Kevin Ackerley's 'Pathway to the Setting Sun' in 1994, from the North Island's East Cape to the West Cape of Fiordland

                     Erik Bradshaw's Ski Traverse of the Southern Alps in 2011

                     Lydia McLean, Allan Brent, Alexi Belton completed a Te Wai Pounamu Traverse in 2016

                     Tom Hadley, Torea Scott-Fyfe, Maddy Whittaker, Conor Vaessen, Southern Alps Traverse in 2020-21

Criss-crossing the Main Divide certainly enhances the adventure with contrasts between East & West coast experiences, each with their own challenges. In 2013, three friends and I spent 33 days traversing one such Westland variation including walking the length of the Gardens to the Great Unknown and dropping into the Perth. This was one of my formative mountaineering experiences.

There have been many more creative traverses completed since. Climbing the highest peaks en route, skiing or packrafting through Fiordland. This type of DIY create-your-own-adventure is part of New Zealand's DNA.

The frequency of long traverses has increased also. In the 1980s there would be a major traverse every 3-4 years, then from about 2004 there have been trips almost every year. According to Shaun Barnett, that may be as much about people becoming inspired by previous stories, more easily spread via internet and social media, as it is by advanced equipment or new ways of travelling.

Sport Alpinism

Though a central element of alpinism is the pursuit of virgin terrain and first ascents, there is also much to be said for repeating a great or historic classic and trying to improve on the original style. In the 2019 American Alpine Journal, Colin Haley describes what he coins Sport-Alpinism: "Sport-alpinism is essentially the art of creatively inventing new challenges when the most natural challenge—simply ascending the face of a mountain—is no longer difficult enough to truly inspire a climber or demand all of his or her skill. Climbing solo, climbing fast, traversing multiple peaks, enchaining multiple routes or climbing in winter are all dimensions of sport-alpinism."

In the theme of Sport-Alpinism, once the natural challenge of simply traversing from Arthur's Pass to Mount Cook was achieved, people have continued to push into new dimensions: winter - the ski traverses; harder terrain - the west coast traverses; distance - the entire Southern Alps and more; solo - Michael Abbot's 5-month odyssey. There is only one dimension that has not seen as much attention: speed.

How light & fast could you traverse from Arthur's Pass to Mount Cook? We wanted to find out.

Inspiration

After spending some time traversing more of the Canterbury valleys during a 3-week ski traverse in the spring and reading of all the history about those early expeditions, I became inspired to attempt a similar line focused more on the Canterbury ranges, but in a lightweight style. Instead of 33 days, as my first trip had taken, or 21 days as the ski version spanned, the goal was to complete the route in 6 days, crossing 6 passes between 6 major catchments.

Sam in the lower Unknown Stream

My companion was Sam Spector. He had contacted me for beta on a similar trip, so I convinced him to join me on the route I was scheming. All of a sudden it was on.

To achieve this, we needed to wait for a perfect forecast since any rain would put a crossing of the Rakaia, Godley or Murchison rivers in jeopardy. With the typical multi-week trip you can't pick your weather, you need to set a starting date and take what comes. But if the trip is short enough, you can wait for a good forecast. I think the ability to be flexible is a major key to success in mountaineering.

On McCabe & Morse's 1949 trip, of course they didn't have forecasts, so they walked into Carrington with 60 pound packs, only to be hut bound for the next 4 days in torrential rain, eating most of their food. Luckily, they had brought a rifle and over the next week subsisted on venison steaks, a Canadian goose, and hare soup. Folks had more patience and ingenuity back then.

Thanks to Rakaia helicopters, we had food flown into Lyell Hut with the CMC hut building crew, and the same pilot took food into Mathias Hut with a load of hunters. I already had a stash in St Winifred hut, or so I thought - it was eaten by the time we got there! Three food drops for a six day trip meant only carrying 1-2 days of food at any time. Cheating? We waited for the elusive "6 day high" all through December, and finally it arrived. A full week of clear, calm weather.

The route

In general we chose a route similar to the early expeditions, taking variations for expediency and to explore different valleys. From the Waimakariri, instead of the common Harman/Whitehorn crossings, we decided to shoot directly over into the Burnet stream past Barker Hut. We followed the traditional Unknown Col into the Mathias and Observation Col into the Rakaia and arrived at Lyell hut in the evening of the third day to find the CMC hut crew busy at work on the new hut. We enjoyed a delicious 20 year old Speights that had been uncovered from the old hut, cooled by a nearby stream. Halfway in distance, but not in effort.

Up the emaciated Lyell glacier, we were able to go directly up the Lyell icefall amongst a jumble of seracs, a strange place to be in running shoes. From Rangitata Col we looked over the Gardens glistening and had no intention of dropping into the Frances glacier. With perfect weather we took the high route from Lambert Col over Tyndall & Newton, weaving around Perth Col and Schrund Punk to find an easy but exposed traverse (for running shoes) to Disappointment Saddle. It was a glorious line; we were quite fortunate to be there.

Having crossed Terra Nova a few months prior, we chose a different crossing to the Godley, this time up the Forbes and over Twilight Col, leading us directly to Eade Memorial Hut. Now into five days of high pressure, the rivers were all low and the air was warm. We followed the footsteps of the Alpine Kids over Mt Acland into the Aida Glacier, feeling the burn, but it was all downhill from here right? Wrong. The long tumble of moraine down the Murchison Glacier would gift us a further 1200m additional vertical to test our resolve. 

At the head of the Murchison Lake

At the end of one of NZ’s greatest moraine bashes we were grateful to find food in Liebig hut as all we had left were sweet chili coated peanuts. Long trips are not meant to end easily, confirmed by the endlessly undulating crossing of the Tasman moraine and Husky slip. Walking out beneath the towering Caroline Face of Aoraki reassured us that we had arrived in Hermitage country, bringing one dream to an end.

Final Words

There is something beautiful about choosing your own path, your own style, like an artist painting a deft red line through a topographic canvas, and the evolution of traverses between Arthur's Pass and Mount Cook and beyond is testament to this. Those early expeditions were explorations of the land, today they become explorations of the mind. What is possible?
