Isdal Woman Day – November 29, 2025

Isdal Woman Day is observed on November 29 of every calendar year. It’s named after the Isdal Woman, an unidentified woman whose lifeless body was found in 1970, in Norway, close to Bergen. The aim of this day isn’t just to raise awareness of this unsolved mystery, but more importantly, to pay tribute to and remember all those who have died in mysterious or disputed ways, especially so if their remains weren’t able to be identified. It’s also a day to reflect on their families and loved ones. It’s hard enough to deal with grief, but it’s even worse if you don’t know what exactly happened.

History of Isdal Woman Day

On the afternoon of November 29, 1970, a man and his two young daughters were hiking in the foothills of the north face of Ulriken, Norway, in an area known as Isdalen (“Ice Valley”). It’s also called “Death Valley” due to the area’s history of suicides in the Middle Ages, and the more recent string of hiking accidents. They noticed an unusual burning smell and one of the daughters found the charred body of a woman located among some rocks. The family returned to Bergen and notified the police.

Examining the body, the police discovered that the front of her body and her clothes had been severely burned and she was unrecognizable. Near the body, there was no campfire, but there were several items affected by the fire, including a plastic passport container, an empty bottle of St. Hallvard liqueur, traces of burned paper, and beneath the body was a fur hat which was later found to have traces of petrol. All identifying marks and labels had been removed or rubbed off. An autopsy revealed that she had died from a combination of incapacitation by phenobarbital and poisoning by carbon monoxide. She had consumed between 50 and 70 Fenemal brand sleeping pills, and 12 more were found next to her body. Soot was also found in her lungs, indicating she was alive as she burned, and her neck was bruised.

The last time she had been seen alive was on November 23 when she checked out of Room 407 of the Hotel Hordaheimen. Based on handwritten check-in forms, police were able to determine that she had traveled around Norway and Europe with at least eight fake passports and aliases, she had previously stayed at several other hotels in Bergen and was known to change rooms after checking in. For these reasons, many believe that she was a spy and some authorities think there is evidence she was murdered. On February 5, 1971, she was given a Catholic burial, based on her use of saint’s names on check-in forms, in an unmarked grave within the Møllendal graveyard in Bergen. The case was reopened in 2016, and new information came to light since, but she remains unidentified to this day.

How to Observe Isdal Woman Day

  1. Listen to the “Death in Ice Valley” podcast

    This is a true-crime podcast produced by N.R.K. and the B.B.C., following a two-year investigation into the Isdal Woman case. It instigated a crowd-sourcing campaign for new leads in the investigation and uncovered where she was likely born.

  2. Spread the word for recent unsolved deaths

    Unfortunately, this kind of thing happens very often. Look into recent unsolved cases of deaths near you, especially ones where the victim couldn’t be identified, and let friends, family, and followers on social media know about it. It may not be too late yet.

  3. Donate to charities dedicated to these cases

    While looking for cases like these, you may find charity organizations dedicated to these sorts of deaths, like the Cold Case Foundation, or fundraising pages for individual cases set up by family members of the victims. Donating to them and letting others know is another good thing you can do on this day.

Why Isdal Woman Day is Important

  1. People must know about these cases

    The more people hear about these things, the more likely it is that they come with new leads. Spreading the word is the most we can do as normal citizens to get closure on these cases.

  2. It’s a day to think about the victim’s families and loved ones

    As we’ve said, it’s hard to deal with grief, it’s harder to deal with a homicide, but it’s even worse when you don’t know what happened. On this day, we should reflect on how these people feel.

  3. It reminds us to try to stay safe

    When you go out or leave a friend’s house to go back home, let others know, let them know you arrived safely. You don’t need to be paranoid about something happening to you, but it’s important to at least reassure others that you’re safe out there.
