Expedition Facts

Dr Gareth Andrews and Dr Richard Stephenson reached the Geographic South Pole at 6.30pm on the 18th January 2023 proud to have completed the 1404** kilometer expedition from the true coast of the Antarctic Continent (PECS* Terminology).


Dr Andrews and Dr Stephenson were attempting to complete the longest unsupported ski crossing of Antarctica. Their intended route would take them from the true coast of Berkner Island on the shores of the Weddell Sea to the base of the Reedy Glacier on the Ross Ice Shelf, a distance of 2023 kilometers.


Dr Andrews and Dr Stephenson had a total of 73 days in which to complete their intended 2023km expedition. This was the maximum amount of time that the Antarctic expedition season would allow them before they had to leave Antarctica.


Weather delays from Punta Arenas, Chile to Union Glacier, Antarctica meant that the team could not start their intended expedition until 7 days later than planned. This left only 66 days to complete the 2023 kilometer expedition, which would have required an average daily distance of 30.65 kilometers.


To complete such an audacious challenge weather and snow conditions would have to be very favourable for the duration of the expedition. This did not eventuate and it has been an extremely challenging Antarctic season for all expeditions on the continent.


The team started the expedition on the 14th November with 165kg sleds each on the very edge of the true coast Antarctic continent, amongst the Emperor Penguins and Icebergs of the Weddell Sea. Excellent progress was made across Berkner Island and the Ronne-Filchner Ice Shelf before 200 kilometers of soft powder snow through the Pensacola Mountains and more than 380 kilometers of solid, unbroken sastrugi (S84040 to S880) significantly slowed the team’s progress.


8 days from the South Pole Dr Andrews and Dr Stephenson made the difficult decision to end the expedition at the South Pole. It became clear that the Antarctic summer expedition season would prove too short the team to complete the crossing attempt ending at the base of the Reedy Glacier on the Ross Ice Shelf.

** Note on distances: Our total final expedition distance was 1404km. It is worth noting that this is slightly longer than the 1353km recorded on the tracking map embedded in our website. The tracking map is based on tracking waypoints automatically uploaded from a Garmin 66i inReach device every 2 hours assuming a straight line is followed between each point. This therefore represents a relatively low resolution picture of our movements. We also used Suunto 9 Peak Pro GPS-enabled smart watches to continuously track a much higher resolution picture of our exact movements taking into account weaving in and out of sastrugi fields etc. so this therefore provides the final more accurate expedition distance of 1404km.

Expedition Summary

In a triumph of mental and physical resilience and the spirit of adventure we reached the Geographic South Pole at 6.30pm on the 18th January extremely proud to have completed the grueling 1400 kilometer journey from the very edge of the Antarctic continent. We have achieved the realization of a childhood dream and our arrival at the South Pole celebrates three years of meticulous planning and preparation by all the Antarctica 2023 team.


Growing up in the wilds of the UK, before making our homes in Australia and New Zealand, we were inspired by the tales of the explorers from the heroic age of polar exploration. Scott, Shackleton and Mawson formed an influential part of our adventurous upbringing and from an early age we knew that one day we would follow our heroes South to the frozen continent.


After 3 years of planning and preparation the Basler aircraft dropped us on the North coast of Berkner Island on the shores of the Weddell Sea. At that moment we were probably among the most isolated people on the planet. Our first task was to turn our backs on the South Pole and ski 10 kilometers north to ensure that we started our expedition on the true coast of Antarctica amongst the Emperor Penguins and Icebergs of the Weddell Sea. The enduring memory of the start of our journey will be staring out across the sea ice and icebergs in the glorious Antarctic sunshine remembering the history of past expeditions that have also attempted a journey across Antarctica from the true coastline of the continent, most notably Sir Ernest Shackleton’s Endurance expedition.


The intention of the Antarctica 2023 expedition was to attempt the longest unsupported ski crossing of Antarctica (PECS* Terminology), starting from the North coast of Berkner Island and finishing at the base of the Reedy Glacier on the Ross Ice Shelf.


Our motivations for attempting such an audacious journey come from our love of adventure and the polar regions and our deep desire to immerse ourselves in the wild and uncompromising Antarctic environment. The time we have spent together in the high Arctic, Greenland, Iceland and Svalbard has instilled in us a passion for the polar regions and willingness to conserve these last true wilderness areas for future generations.


In attempting this expedition we had two further objectives, to collect 66 days of critical climate and meteorological data and to inspire a generation of young people to conserve Antarctica into the future through our work with Scouts Australia, Scouts New Zealand and World Scouting.


Our expedition started on the 14th November 2022 with sleds weighing 165kgs. We had enough supplies for a 66 day, 2023 kilometer journey across Antarctica. Our arrival into Antarctica was delayed by 7 days as the blue ice runway at Union Glacier was heavily snowbound after the severe Antarctic Winter. It was an ominous sign of things to come. The delay meant that our planned 73 day expedition was now cut down to 66 days and we faced a daunting daily average of 30.65 kilometers to achieve our objective – a formidable but not impossible challenge.


We began the expedition by dragging our sleds from sea level to the high point on Berkner Island at about 800m above sea level. On day 2 we had our first taste of how severe the Antarctic weather could be. Howling, gusting winds, freezing temperatures and minimal visibility saw our progress fall to 10 kilometers a day as drifting snow made dragging our heavy sleds uphill almost impossible. After this initial storm we made excellent progress across Berkner Island averaging 22-24 kilometers a day – exactly what we needed to be achieving at this stage of the expedition. We completed the crossing of Berkner Island as planned in 18 days and embarked on our crossing of the Ronne-Filchner Ice Shelf. This section of the expedition brought us to the base of the Wujek Ridge and the start of the mainland of Antarctica itself, our gateway through the Pensacola Mountains and through to the polar plateau.


The ascent of the Wujek Ridge went exactly as planned and we completed it in a day. A huge, steep wall of snow and ice the Wujek Ridge took two journeys to ascend. We cached one sled each at the base, donned our crampons and hauled the other sleds up before returning and repeating the journey a second time to collect the sleds left behind. Exposed crevasses with fragile snow bridges greeted us at the top but we negotiated a route through without incident.


The Sallee and Median Snowfields lay before us now and we knew that to be in with a chance of making the crossing we would need to start increasing our daily distances. We faced 200 kilometers of soft, knee-deep powder snow that slowed our progress but we maintained our daily distances at an average of 22-23 kilometers per day. We traversed the snowfields with the mountains of the Forrestal Range to our East and the craggy spires and hanging glaciers of the Neptune Range to our West.


Just before S84040 we hit our first significant sastrugi, iron-hard ridges of snow and ice forged by the fierce winds of the Antarctic winter. We knew from past expeditions that this was a sastrugi-prone route but previous reports had sastrugi starting at around S85030, almost a full degree of latitude (111km) later. From this point we experienced solid, unbroken sastrugi for more than 380 kilometers. Huge waves of ice, some 2.5 meters high and as big as small houses, stunningly beautiful structures but devastatingly difficult to traverse. The physical and mental toll of travelling hundreds of kilometers in this terrain saw our progress fall to 18-20 kilometers per day. We gave everything we had to move forward as far as possible everyday and we would stumble with exhaustion into camp each evening. Most nights we would struggle to find a flat place to pitch our tent amongst the broken uneven ground.


At S880 the sastrugi finally relented but temperatures dropped and the drag on our sleds had increased dramatically. A strange phenomenon occurs when it is very cold; the crystal surface structure of the snow becomes rougher and there is much more friction when dragging sleds. Through the last two degrees of latitude, temperatures remained at around -300C as we made our way towards the South Pole. It was at this stage that we made the difficult but necessary decision to end our expedition at the South Pole. It was clear that we did not have enough time or supplies to go more than a couple of days past the pole. The correct decision was to finish the expedition at the South Pole.


We arrived at the Geographic South Pole, friends and team-mates, at 6.30pm on the 18th January 2023 elated to have completed such an arduous expedition from the very edge of Antarctica. Whilst the Antarctic summer expedition season proved too short for us to make the crossing onto the Ross Ice Shelf, we are immensely proud to have reached the Geographic South Pole from the true coast of the Antarctic continent. To have given everything and reached the bottom of the planet in a season when great swathes of our route had been carved up by fierce winter storms leaving dense sastrugi and deep drifting snow is undoubtably one of the greatest achievements of our lives.


We have fulfilled a childhood dream and experienced Antarctica for 66 days in all her brutal, spectacular glory. We are extremely proud to have achieved our objectives and collected a transect of crucial climate and meteorological data and brought more than 60,000 Scouts on this journey with us.


We would like to say a huge thank you to our sponsors and supporters for your unwavering support and for helping make this wonderful project a reality.

South Pole!

We reached the Geographic South Pole at 6.30pm on the 18th January, tired but elated to have completed the 1400 kilometre journey from the coast of the Antarctic continent.

Our final day started cold (-32degC) and overcast with a freezing wind blowing from the North. After almost a week of clear skies and light winds the Antarctic plateau had an ominous feel to it. We were up and eating breakfast by 4am, an early start after crawling into our sleeping bags at midnight. The day before had been tough and very long. We were camped 27kms from the South Pole and ready for one last big effort. There was a feeling of excitement and trepidation between us as we stepped into our skis and clipped into our sled harnesses for the final time. The plan was simple, one foot in front of the other and don’t get frostbite. We knew if we stuck to the plan we  would get there in 12 hours time.

With 10kms to go we saw a glint on the horizon, the sun reflecting off something metallic. Our first glimpse of civilisation in 66 days. A few minutes later it was gone as the sun was again immersed in cloud. We skied on into the gloom and soon dark objects began to emerge on the horizon and the Amundsen-Scott South Pole Station came into view. It was an emotional moment for both of us, three years of hard graft and a childhood dream finally realised. I welled up thinking of the end of our journey and of home. The tears made my goggles mist up and then freeze annoyingly!  I pulled myself together and prepared to ski the final 8km to the South Pole. After being dropped off on edge of Berkner Island 66 days before we had finally reached the end of our journey. We had pushed as hard as our bodies could go. No rest days, late starts or early finishes – we gave it everything everyday. There were many times when we thought we might not make it to the South Pole as we moved agonisingly slowly through some of the hardest conditions we have ever faced. The fate of the expedition depended on us not breaking ourselves or our gear. Our priority was to stay physically fit and healthy – no broken bones in the sastrugi or cold injuries in the -30degC temperatures.

We nursed ourselves and our gear through. Two broken skis, three broken bindings and numerous other bits of kit that we had to fix to keep moving forward. Failure of any of these critical items would have meant a call for rescue.

At 6.30pm on the evening of the 18th January we finally stood at the Geographic South Pole, friends and team-mates, having completed the toughest journey of our lives.

A huge thank you from Rich and I to all of you who have supported and sent us messages along the way. This will be our last daily blog post as we begin our journey home to our families. We fly from the South Pole to Union Glacier this evening and then on to Punta Arenas tomorrow, weather permitting.

Our generous sponsors have contributed to making this journey possible but a large part of this expedition is self funded so any donations help www.Antarctica2023.com.au

Day 66

I have just received a call from Gareth, that he and Richard have made it safely to the South Pole! A tough day, with 27km covered, but the joy of seeing the Pole in the distance and skiing in to see people waiting was exhilarating. They are exhausted and looking forward to a rest after this huge accomplishment.

They hope to fly back to Union Glacier Camp tomorrow and then to Punta Arenas on Friday if weather permits.

I will send updates as soon as I have them. Here at Expedition HQ we can celebrate their epic journey and rest a little easier that they have made it safely.

We can’t wait to have them both home.

Andrea Andrews – Expedition Manager and Gareth’s incredibly proud wife.

Day 65

Well folks, this is it! After 65 days and 1375km we’re camped just 27km from the pole ready for the final push tomorrow!

It’s been an incredible journey, both a huge privilege to immerse ourselves so completely in this stunning wilderness, but also unquestionably the hardest mental and physical challenge of our lives.

It remains tough to the end, today was yet another endless sea of sticky lumpy soft snow and I’m sure tomorrow will be just the same but we’ve just got to get our heads down and dig deep one last time. Thank you to everyone following us at home, it’s your support that has kept us going, wish us luck one last time and hopefully this time tomorrow we’ll be at the South Pole!
