Mount Sidley

Do you dream of the unexplored and crave the extraordinary?

Be among the few to have climbed Antarctica’s highest volcano and one of the Volcanic Seven Summits. Join the ultimate mountaineering expedition to Mount Sidley 14,058 ft (4285 m) and stand atop one of the most remote summits on earth.

Sidley is a huge mountain, set on the white expanse of the Polar Ice Sheet. This majestic peak features a 5 km wide caldera and sheer walled amphitheater, created by an explosive eruption 4.7 million years ago. Blue-ice slopes guard the upper mountain and fantastical snow mushrooms sprout along the upper ridge, leading to the summit.

No two Antarctic adventures are the same and details may not happen exactly as described. This, however, is part of the excitement and adventure of Antarctic travel. Exact timeline and details may and will vary due to changes depending on logistical demands and weather. Therefore flexibility is required. We have planned a relaxed schedule with reserve time. Allow yourself to enjoy this unique experience without the stress of pending commitments.

Planned Itinerary:

Day -4 to 3: Arrival in Punta Arenas and Union Glacier (Antarctica)

Day -4: International flight from home destination via Santiago de Chile to South America

Day -3: Arrival in Punta Arenas, Chile – transfer to our comfortable hotel

Day -2 to -1: Preparations and excursions in Punta Arenas We begin the journey in the southern gateway city of Punta Arenas, Chile. We shall spend some days here preparing our food and equipment for the expedition and getting to know each other.

Day 1: Flight with Iljushin IL76 to Antarctica From Punta Arenas we fly in one of the most stunning aircrafts in polar aviation, a specially equipped Iljushin IL76 transport jet, 4 ¼ hrs to the American Union Glacier airbase in Antarctica´s Ellsworth Mountains. We land on the ice runway and settle in at Union Glacier Camp.

Day 2-3: Final expedition preparations in Union Glacier Camp. We review our expedition plan, acclimatize and finalize preparations as well as camp set up.      

Day 4 to 10: Climb Mt. Sidley

Day 4: Flight with private Twin Otter skiaircraft to Mount Sidley Depending on weather we fly almost 900 kilometers over the spectacular mountains and the vast emptiness of West-Antarctica to the remote Executive Committee Range. Our ski aircraft lands near Mount Sidley and we establish base camp at approximately 2000 meters altitude, below the imposing bulk of the mountain. Now we are really “out there”, in the middle of the worlds largest desert and get to absorb the reality of our exposed location feeling like Astronauts on another planet. The brittle cold is palpable but with our perfect expedition clothing and equipment we are well prepared for all that Antarctica can throw at us. We set up tents and give ourselves a night of acclimatizing to the thinner air here at 2.000 meters elevation. Our private Twin Otter and aircrew will be standing by all time. 

Day 5-10: Five days for the mountain ascent
Mount Sidley offers several interesting route options, including a longer easy ascent from the north side and a steeper climb up the west ridge from the Bennett Saddle. The route that we climb will be decided depending on the landing site as well as the team‘s skill and experience. From base camp to the summit involves approximately 2200 meters of elevation gain. We climb alpine style, setting two intermediate camps on the mountain and dragging or carrying our food and equipment with us.  Storms and blizzards are rare up here at this time of the year and we are more likely to experience the fragile stillness of the high pressure system in the high and dry Antarctic interior. Warm clothing, heat generating activity, a high calorie food and cosy camping gear make the elements of Antarctica not only tolerable but truly enjoyable. We will experience 24 hour daylight. So there is no shortage of time to really see and feel the true Antarctica like just very few people have experienced the icy paradise before. Summit day offers spectacular views as we follow the summit ridge along the rim of the caldera. Below us the sheer walls of the Weiss Amphitheater drop away 1200 meters. We weave our way between a maze of fantastical ice “mushrooms”. These spectacular snow features are formed by wind and moisture depositing rime ice on small obstacles, over the years evolving into massive structures. Our select group has climbed in one of the most stunning landscapes on this planet to the summit of one of the most remote peaks on earth – a magnificent achievement that will live with us for the rest of our life. Following our summit success we return to high camp and retrace our steps back to our base camp.

Day 11-12: Return Journey to Punta Arenas

Day 11: Return to Union Glacier Camp with Twin Otter Fly back to Union Glacier Camp. Celebrate our achievement with a glass of wine and a delicious, fresh meal prepared by the ALE chefs.

Day 12: Flight back to Punta Arenas and transfer to the individual hotels

Flight home: We recommend you to book your return flight for a week after we returned from the Antarctica so we have a buffer for possible delays, which are common with expeditions to the Antarctica. In case you should have any extra time in Punta Arenas, the Team will gladly provide you with information about excursions and sightseeing in the area. At departure day: transfer to the airport and individual flight home.

Geography

Mount Sidley, standing at 4,285 meters, dominates the icy West Antarctic landscape, rising prominently within the vast Marie Byrd Land. This shield volcano is not only the tallest volcano in Antarctica but also the highest peak in the region. Mostly blanketed in snow, Mount Sidley features a broad caldera stretching five kilometers across and a dramatic, amphitheater-like depression plunging 1,200 meters, the result of a powerful eruption around 4.7 million years ago. The upper slopes are guarded by blue ice and crowned with unusual snow formations that create a labyrinthine path to the summit.

Marie Byrd Land spans between 158° W and 103°24’ W in West Antarctica, covering approximately 1.6 million square kilometers, nearly triple the area of France. Despite Antarctica’s general isolation, this area is particularly remote and is often described as the world’s largest “no man’s land,” as it remains unclaimed by any nation. Its untouched state is evident: there are no fishing vessels, harbors, runways, or research facilities—just pristine polar wilderness.

A series of active yet seldom-studied volcanoes pierces the ice sheet here, forming one of the planet’s most intriguing volcanic zones. Along a 900-kilometer section of Antarctica’s Pacific Coast, 18 major volcanoes rise from the ice, mirroring the size of the Cascade Range in North America. Within this range lies the Executive Committee Range, which includes Mount Sidley, towering 2,200 meters above the icy expanse. Nearby is the Bentley Subglacial Trench, more than 2,500 meters deep and the world’s deepest point not covered by ocean.

History

The renowned American polar explorer Richard Evelyn Byrd conducted three expeditions between 1929 and 1941 to explore this part of Antarctica, naming it after his wife, Marie. During a flight on November 18, 1934, Rear Admiral Byrd discovered a massive volcano, which he later named after Mabelle Sidley, the daughter of a supporter of the Byrd Antarctic Expedition.

Today, Mount Sidley is the only peak in the range not named after a member of the U.S. Antarctic Service’s Executive Committee. Mount Sidley was first summited on January 11, 1990, by New Zealander Bill Atkinson, followed by two additional ascents by U.S. Antarctic Scientific Program field teams in the early 1990s. It wasn’t until 2010 that the mountain saw its third ascent. While Mount Vinson (4,892 meters), the tallest peak in Antarctica, has been climbed several hundred times, only a handful of mountaineers and true explorers have stood atop Antarctica’s highest volcano to this day.

https  Insurance

We strongly recommend taking out a suitable travel insurance for Antarctica (including trip cancellation, interruption, medical and luggage insurance).

Due to the exposed location of this expedition, only very few insurance companies offer a suitable offer and this must be put together individually for each traveler. We’re happy to provide you with an individual offer upon request or after booking

language  Entry Requirements

EU or Swiss citizens:

Chile:
When entering the country, you need a passport with a validity of at least 6 more months. Visa-free entry is possible for tourist purposes for up to 90 days.

Information about recommended vaccines and health regulations: http://www.who.int/ith/en/

Travelers must be able to prove their return or onward ticket when entering the country.

More detailed information regarding entry, visa and health requirements for this travel destination will be provided once you’ve communicated your nationality.

work  Equipment

You need to bring your own personal equipment including a sleeping bag with a comfort zone for -20° C. Please consider that the temperature is likely to drop below -30° C, and a strong win-chill-effect and storms can occur. Following your booking we will send you a detailed equipment list. We will be happy to advise you personally during the selection and purchase of required equipment. With years of expedition experience, we know what has proved its worth and what not.

insert_chart_outlined  Difficulty/ Technique

The ascent always lies in the member’s personal responsibility, while led by the mountain guide and expedition leader. Members must be able to move safely and independently in mixed terrain (rock, snow, ice) and – if required – independently build rope teams under the guidance of the mountain guide. Cooperation, camaraderie and support on the mountain increases the chances of success for all.

The guide is there to provide guidance for the whole group, the possibilities for him to respond to individual needs is limited. It is imperative that members adhere to the instructions and decisions made by the mountain guide. Regardless, each member must know their own physical limits, and be able to make a timely decision to turn back.

perm_identity  Physical Fitness

A key success factor in expeditions is being in good shape. Train in the months before the expedition! Several hour climbs with a backpack and around 1000 vertical meters per day should not be a problem for you. Mental training is also advised for this very challenging expedition. We will gladly provide individual advice on how to best prepare yourself mentally and physically for an expedition!

local_hospital  Health

We recommend that each member undergoes a medical examination prior to the expedition. Good health is a prerequisite for participation. Particularly important is a visit to the dentist because previously unnoticed dental problems can become quite acute due to the sudden change in pressure conditions in higher altitudes.

how_to_reg  Experience

Although Mount Sidley is not technically difficult, it is a serious mountain due to its extremely remote location, the cold of up to -30°C, elevation of 4285 meters at a very high latitude of 77°S, which makes the mountain “feel” much higher. You should have experience with multi-day peaks in cold environments; climing at altitude 4500 meters and with unsupported alpine-style ascents in winter conditions. Proficiency with ice axe and crampons on slopes up to 45 degrees and with roped glacier travel carrying a 20 kg backbag is essential. We are very familiar with the charm and attraction of a high mountain! However, we want to make certain that you can ascend safely, come back alive, and be able to enjoy the expedition while on it and not afterwards. When booking, please let us know which heights you have already reached and which high mountains you have climbed. If you are a newcomer, no problem, we offer a bespoke program aimed to train you for reaching your desired destination.

We offer a special introductory weekend for all those who want to learn about – or refresh their knowledge of – all the skills and techniques needed on an expedition. More info here.
