BBC Future has brought you in-depth and rigorous stories to help you navigate the current pandemic, but we know that’s not all you want to read. So now we’re dedicating a series to help you escape. We’ll be revisiting our most popular features from the last three years in our Lockdown Longreads.

You’ll find everything from the story about the world’s greatest space mission to the truth about whether our cats really love us, the epic hunt to bring illegal fishermen to justice and the small team which brings long-buried World War Two tanks back to life. What you won’t find is any reference to, well, you-know-what. Enjoy.

In the bleak, almost pristine land at the edge of the world, there are the frozen remains of human bodies – and each one tells a story of humanity’s relationship with this inhospitable continent.

Even with all our technology and knowledge of the dangers of Antarctica, it can remain deadly for anyone who goes there. Inland, temperatures can plummet to nearly -90C (-130F). In some places, winds can reach 200mph (322km/h). And the weather is not the only risk.

Many bodies of scientists and explorers who perished in this harsh place are beyond reach of retrieval. Some are discovered decades or more than a century later. But many that were lost will never be found, buried so deep in ice sheets or crevasses that they will never emerge – or they are headed out towards the sea within creeping glaciers and calving ice.

The stories behind these deaths range from unsolved mysteries to freak accidents. In the second of our new series Frozen Continent, BBC Future explored what these events reveal about life on the planet's most inhospitable landmass.

1800s: Mystery of the Chilean bones

At Livingston Island, among the South Shetlands off the Antarctic Peninsula, a human skull and femur have been lying near the shore for 175 years. They are the oldest human remains ever found in Antarctica.

The bones were discovered on the beach in the 1980s. Chilean researchers found that they belonged to a woman who died when she was about 21 years old. She was an indigenous person from southern Chile, 1,000km (620 miles) away.

Analysis of the bones suggested that she died between 1819 and 1825. The earlier end of that range would put her among the very first people to have been in Antarctica.
