Telefon Bay on Deception Island

Telefon Bay on Deception Island

Explore volcanic craters and ash cliffs on this active volcano

Deception Island is the eroded cone of an active volcano, that last erupted in 1967. It sits in the Bransfield Strait and is part of the South Shetland Islands. Telefon Bay is on the northwest coast of the volcano and is overlooked by Telefon Ridge.

Despite the name, the bay has nothing to do with communications! It was first mapped in 1908 and was named after a Norwegian ship, the SS Telefon, that had been damaged and was put aground here for repairs later that year before being refloated.

The backdrop to the beach is dramatic. In the rising land behind it, you will see a number of volcanic craters, some of which are up to 150ft deep - although gradually being filled in with ice and sediments. To the east and west are cliffs made of ash that were the result of activity in the 1967 eruption that impacted Telefon Bay.

You will be allowed to roam freely here, provided you stick to the main paths and give any penguins a wide berth! You will often see scientific equipment placed around the bay that is used for monitoring any seismic disturbances - it will be clearly marked to help you avoid it.

The shallow beach here is a favorite place for seals to haul out, and you can often encounter both Weddell and fur seals as you come in for a landing.

Highlights Close to Telefon Bay on Deception Island

Elephant Island

Elephant Island is one of the outermost of the South Shetland Islands. The roots of its name are argued to be one of two reasons. Either the fact that Elephant seals were seen hauled out here in large numbers by the first person to discover and map the island, Captain George Powell in 1821, or that the island’s shape is uncannily like that of a baby elephant’s head with trunk extended! The island remained unexplored for many years thanks in part to its lack of resources (just small numbers of seals and penguins and no native plants) and partly because of its steep volcanic rocks, presenting few landing points. However, in 1916 Elephant Island became immortalized as the scene of the beyond-all-odds survival story that was Ernest Shackleton’s ill-fated Antarctic expedition. After their ship Endurance was lost to the treacherous ice in the Weddell Sea, the 28 crew were forced to make a perilous escape attempt. After months in open boats and stuck on drifting ice sheets, the team arrived at Elephant Island. Here they set up a base to stay while Shackleton and five members of his crew set sail in an open lifeboat for South Georgia - a journey of over 800 miles - to seek a rescue ship. This stunning tale of endurance, determination, and the human spirit is brought home to visitors to Elephant Island by the Endurance Memorial at Point Wild. You can also see breathtaking views of the Endurance Glacier - named after Shackleton’s lost ship - as well as the stunning rocky terrain and its gentoo penguins and seals.

Pendulum Cove

Pendulum Cove is a small bay on the northern side of the natural harbor formed by the flooded cone of the live volcano that is Deception Island. One of the South Shetland Islands, Deception offers several visitor points, of which Pendulum Cove is definitely worth a visit. The cove came by its unusual name as it was named by the British expedition of Henry Foster in 1829. The site here was used by the explorers to take magnetic measurements as well as studying the movement of pendulums this close to the south pole. It was one of these experiments that gave the cove its name. If setting foot on the other sites on Deception Island doesn’t feel like you are standing on an active volcano, Pendulum Cove will remind you! In places here, water heated by geothermal activity can reach 160F. Your expert Antarctic guide will show you safe areas where hot water mixes with the cold Antarctic seawater to provide a most unusual polar “spa” experience. It’s warm while you are in the water, but you might regret it when it’s time to get out and get dry! There are Gentoo and chinstrap penguins on the beach, and they don’t seem to mind sharing their warm water with human visitors - just remember that in Antarctica, wildlife has the right of way! This part of the volcanic crater was hit hardest by the last eruption in 1969. There is a historic site here, the remains of Chilean research station Base Aguirre Cerda that was overwhelmed. The twisted, rusting fragments of the remains can be viewed from a safe distance. A somber reminder of the forces still at work under your feet. You may well see scientists at work and come across instruments. These are part of the real-time monitoring of seismic activity on Deception Island and Pendulum Cove in particular.

Whalers Bay

Whalers Bay is a small natural harbor on Deception Island, one of the South Shetland Islands. An active volcano, the crater forms a natural sheltered inlet that was historically used by sealers and then whalers from the 1820s. The geography makes it a perfect place for ships to shelter in rough weather, and Whaler’s Bay contains some of the most significant whaling artifacts and remains to be found in the whole of Antarctica. As your ship sails through the narrow “break” in the volcanic caldera known as Neptunes Bellows, the wide, circular beach of Whaler’s Bay is found to the right. The beach runs uninterrupted for one and a quarter miles and was used as a runway in the 1950s and 1960s when the site was the main hub of British Antarctic air movements. The hangar that was built in 1960 can be visited at the northern end of the beach where you can also see a roller that was used to maintain the runway. At the southern end of the beach are large, rusted oil tanks, and behind them are buildings from the period 1906 to 1931. There was a significant whaling industry here, with the sheltered and shallow beach making it an ideal place to land whale carcasses and process them. While you explore all this remarkable human history, please remember that you are standing on an active volcano! The instruments you may see around the beach in the Whalers Bay area are seismic monitors, and the island is monitored for activity 24 hours a day. The last eruption was in 1969, and this was responsible for some of the mudflows and damage to the buildings and metal tanks that you see here. The penguins don’t seem to be worried, though! Chinstraps and Gentoos can always be seen along the beach here, and it’s not unusual to encounter fur seals who have hauled out to rest and watch the humans. There are also plenty of Antarctic seabirds to see, including petrels, skuas, Antarctic terns, and kelp gulls.
