Join the Mawson’s Huts Society & Help Save Australia’s Antarctic Heritage

After Sir Douglas Mawson’s last visit to the huts in 1931 on the British, Australian and New Zealand Antarctic Research Expedition (BANZARE), the next visits occurred in the 1950’s when at least four French parties visited between 1950 and 1959 in association with establishment of bases at Port Martin and later, Dumont D’Urville in 1956. An Australian National Antarctic Research Expedition (ANARE) visited the site in 1962 and reported the hut full of ice.

In 1967 the Director of the French Antarctic Program noted that the hut had filled with snow and ice between his visits in 1959 and 1962 because ‘some stupid Antarctic explorer had forgot to close it’!

In the 1960’s, four visits by American, New Zealand and French expeditions were made and in the early 1970’s ANARE visited the site four times.  The deterioration in the condition of the huts was reported with growing concern.

The first conservation work was conducted in 1977 by an ANARE team with repairs to the skylights and Memorial Cross and repatriation of some artefacts.

In 1978 a four person ANARE group led by Rod Ledingham constructed the Granholm Hut (named after Peter Granholm, Master of the Nella Dan) for accommodation and placed several metal containers on site for storage of tools and equipment. Work on Mawson’s Huts included excavating the workshop and covering areas of the roof with tape and lead sheets in an effort to reduce the ingress of snow into the hut.  Extensive photographic documentation of the condition of the hut and artefacts was carried out and on return of the expedition to Australia, plans were made for future conservation work.  Tongue and grooved Baltic pine timber to over clad the hut was purchased by the Australian Antarctic Division the following year but it was not until 2007 that the boards were used for the work.

Project Blizzard

In the summers of 1984 and 1985 a private expedition, ‘Project Blizzard’ conducted extensive documentation of the huts and made critical repairs to the supporting timbers inside the main hut.  They installed an Apple Hut supplied by the AAD for accommodation near the Granholm Hut.  Their efforts raised public awareness of the importance of the historic site and the need for a comprehensive conservation plan to save the huts from the ravages of the extreme weather of Cape Denison.






Interior of the Main hut almost completely ice filled. Project Blizzard found broken timbers supporting the roof which threatened its structure and were repaired by the expedition.

ANARE 1986

The next visit to the huts by ANARE was in 1986 when the Sorensen Hut (named after Arne Sorensen, another Master of the Nella Dan) was established to accommodate future planned Mawson’s Huts work parties.  Dr Michael Pearson of the Australian Heritage Commission visited on this occasion and on return to Australia prepared the first Conservation Management plan for the historic site.

Mawson’s Huts Foundation 

David Jensen AM, who was at the time an Executive of Australian Associated Press (AAP), formed the Mawson’s Huts Foundation in 1996.  Sir Peter Derham (now deceased) who had made dedicated efforts through the Mawson’s Huts Conservation Committee to carry out a conservation program joined the Foundation as its Deputy Chairman.

The aim of the Foundation was to raise funds to send expeditions comprising heritage professionals and support personnel to conserve the historic site working closely with the Australian Government through the AAD and Heritage Division.

The Foundation employs an Expedition Manager, Rob Easther AAM, previously an AAD employee who prepares conservation works plans in consultation with the AAD for approval and also makes application for permits and environmental impact assessment for each expedition.  A comprehensive risk assessment is completed before departure and the expedition team, selected by the Foundation, gathers for briefings prior to departure in preparation for the summer’s fieldwork at the Historic Site.

A typical conservation team comprises heritage specialists including an archaeologist, materials conservators and heritage carpenters with additional support personnel such as a doctor, base camp manager and communications specialist. A photojournalist is usually included in the team to ensure the story of each expedition reaches the media and occasionally artists have been appointed who generate funds for the conservation work from the sale of their work.

The conservation work

The Foundation sent built heritage architect Geoff Ashley of Godden McKay Logan and Alasdair McGregor, architect and artist to the Historic Site in 1996 on the Akademik Shokalskiy to assess the condition of the huts and make recommendations for the conservation work. They were ashore for only 24 hours and with perfect weather, used their limited time well.

Besides contributing to the condition report, Alasdair made several sketches in preparation for paintings he would produce on return to Australia to raise funds for the conservation work.

Recommendations from their report formed the basis for the conservation program, which was agreed by the AAD.

At the outset, grave concern for the integrity of the roof of the main hut and workshop due to the eroded state of the tongue and groove boards meant that over cladding the roof was a high priority. Its failure in the extreme winds of Cape Denison threatened destruction of the huts if the wind penetrated the structure. In the 1997-8 summer, the workshop roof was over-clad with Baltic Pine, the same timber used on the original roof.

Throughout following expeditions, the priority of the works program was removal of material from previous visits to the site following Mawson’s last visit and recording of artefacts inside and outside the huts.

A stainless steel bracket was manufactured by the Foundation to support the arm on the Memorial Cross erected in 1912 by Mawson’s men to commemorate the sacrifice of Ninnis and Mertz and which had repeatedly fallen down through the years in the extreme weather conditions. It was an important element to the restoration of the heritage of the Historic Site.

The Sorensen Hut was much too small for the team sizes planned for future expeditions so one of the important tasks of the initial conservation expedition was to double its size and this was completed by the time the group was picked up. With extraordinary teamwork, the group also carried the Apple hut installed by Project Blizzard in 1986 to the Sorensen Hut site and re-installed it on a purpose built platform.

Completion of the over cladding of the main hut in 2006 prevented the ingress of snow and ice from entering the huts and made possible removal of large quantities of snow and ice that had accumulated over the years. Numerous artefacts were discovered and carefully excavated. Recording the humidity and temperature inside the huts ensured any changes that may have been detrimental to the huts were monitored.

The flagpole at the apex of the main hut was removed during the over cladding since it had been eroded to a very fine and vulnerable thickness by incessant wind driven ice particles; a replica was installed. Permission was granted by the AAD to repatriate the flagpole to ensure its proper conservation and ensure it would not deteriorate further. Once conserved, a decision will be made by the AAD as whether it will be returned to the Historic Site and exhibited there or exhibited in Australia.

In 2007 the Foundation expedition constructed a conservation laboratory alongside the modern facility, Sorensen Hut, base for conservation teams. Treatment of artefacts on site has occurred since and the expansion of the Sorensen also allowed for improved accommodation for up to six expeditioners.

Continuing excavation has been followed by re-instatement of shelving allowing replacement of treated artefacts to their former positions.

Work has also been conducted on the outlying scientific huts at the Historic Site to ensure their conservation although the Absolute Magnetic Hut is described as a ‘standing ruin’ and it is accepted that very little can be done to conserve it for the longer term. The Transit Hut is in an advanced state of deterioration but has received specialist treatment in the interests of longer-term conservation.

Mawson’s Huts Foundation Expeditions

1996-97 Built heritage architect Geoff Ashley and architect/artist Alasdair McGregor visited the Historic Site for 24 hours on the tourist vessel Akademik Shokalskiy with Heritage Expeditions returning with an assessment of the condition of the huts and recommendations about their conservation (see pics above).

1997-98 The Foundation chartered the Akademik Shokalskiy and Heritage Expeditions to deliver the thirteen member conservation team to the site to make vital internal structural repairs, over-clad the workshop roof and record artefacts at the site.  A film crew of two made a documentary of the expedition called ‘The Home of the Blizzard’ and Alasdair McGregor produced several paintings to raise funds for future work.

2007-08 With the roof sealed, the selection of this MHF team marked the transition in the works program to a focus on the conservation of the numerous artefacts inside and outside the historic huts.  Their major tasks were to construct a laboratory for the ongoing conservation work and to expand the Sorensen Hut to provide secure accommodation facilities for future expeditions. All this was achieved in the five weeks the team was ashore as well as a comprehensive survey of the artefacts throughout the Historic Site to enable the conservation works for the next few years to be planned.

2009-10 Work achieved included comprehensive photo documentation of the winter quarters, Absolute Magnetic Hut, Magnetograph House and Transit Hut to record condition and snow ingress; memorial cross, proclamation pole and cairns. Platform timbers in the main living hut were reinstated
and excavation of ice in several locations inside the winter quarters under the supervision of the archaeologist. The outside south west corner of the main hut was over clad and documentation and downloading of data from the environmental and vibration monitoring systems and reprogramming were carried out.

The Magnetograph House was opened and the internal condition was assessed; the data logger dating from 2002 season was downloaded.

Photography, cataloguing and treatment of 156 artefacts and repairs to shelving in the main living hut were made. Survey and map of the internal fittings and artefacts inside the Main living hut and workshop were completed.

Air tractor fragments were located in Boat Harbor and returned to Australia for treatment. Archaeological survey completed and exposed artefacts mapped using aerial photography.

2010-11 This team was deployed in two stages due to alterations in the shipping schedule of L’Astrolabe following a helicopter crash on the previous voyage. Three members travelled on L’Astrolabe as an advance party and two later on the tourist vessel, Orion. Despite the abbreviated stay at Cape Denison, the group completed stabilization of the Transit Hut internal frame and continued the extraction of artefacts inside the huts and recording of external artefacts. Two members who had been selected had to be withdrawn due to shipping constraints.

2011-12 A team of seven was selected but due to the presence of the iceberg known as B9B lodged in the entrance to Commonwealth Bay, the expedition was postponed. This proved to be a wise decision as the only visitors to Mawson’s Huts this season arrived by long range helicopters due to the presence of fast ice, blocked into the coast by B9B, the size of the ACT. The Foundation will be monitoring the sea-ice in the region throughout the year and in particular in the lead up to next season’s departure in early December 2012.

Following cancellation of the expedition, two members Ian Godfrey and Marty Passingham, were selected by the AAD to join the AAD Centenary Voyage and a third previous Foundation member Chris Gallagher, was employed as the Field Leader for the AAD shore party. On arrival at the huts, it was found that two skylight covers had blown off the workshop roof and the two Foundation carpenters managed to make vital repairs.
