Two men attempting to recreate an epic 1916 Antarctic expedition by Ernest Shackleton are stranded on a plateau above a glacier after wild weather on the final leg of their journey in South Georgia.
AAP reports British-Australian expedition leader Tim Jarvis and mountaineer Barry Gray were stuck at Shackleton's Gap, but assured their team on Saturday that they were doing well.
Four other members of the expedition and film crew recreating Shackleton's journey over a mountain in South Georgia to an old whaling station at Stromness, have already been evacuated.
The team has already completed Shackleton's crossing of the Southern Ocean in a lifeboat from Elephant Island to South Georgia.
The final leg is a two-day climb over the mountains of South Georgia to reach a whaling station where Shackleton and his men raised the alarm about the sinking of their ship, the Endurance.
The men are wearing the traditional gear of early last century.
Shackleton's ship Endurance became trapped in 1915 in ice and sank 10 months later as it was crushed. Shackleton and his crew lived on the floating ice until April 1916, when they set off in three small boats for Elephant Island.
From there, Shackleton and five crew sailed to South Georgia, reaching their destination 16 days later, and then had to trek over the mountains.
All members of the Endurance mission were eventually rescued with no fatalities.
