Where are finds from glacial ice made globally, and when were the first finds made? The discovery of Ötzi the iceman in 1991 was the first archaeological find from the ice to gain worldwide attention. However, he was by no means the first find from glacial ice. Such finds were reported already in the early 20th century.
Early finds from the ice
The first known find was an arrow recovered from an ice patch in Oppdal in Norway in 1914. Unsurprisingly, it was a very hot summer that year – the early finds are invariably linked to such summers. Finds also appeared elsewhere: a newspaper clip from British Columbia, Canada from 1925 describes an arrow found on ice then.
Even more finds appeared in Oppdal during the very warm summers of the 1930s, when a few finds were also reported from the neighbouring county Oppland (now Innlandet). Things then quietened down until the 1990s,.
The find explosion
Ötzi was found in the Tyrolean Alps in 1991 and became the starting gun for the second wave of ice finds. Six years later, lots of arrows, atlatl darts and paleo-zoological material were reported from the Yukon ice patches and a long-term program was initiated to rescue these finds.
Pretty soon similar finds, but fewer in number, appeared elsewhere in Western Canada (North-West Territories and British Columbia), in Alaska and in the U.S. part of Rocky Mountains. More finds appeared in the Alps as well, especially from the Schnidejoch site in Switzerland.
The dramatic melt in Norway in 2006
A dramatic melting episode in Norway in 2006 led to an explosion of finds here. There had been a few finds melting out in 2002-2003, as a forewarning that something was afoot. In 2006, there was a long and hot autumn, which led to very heavy melting. Hundreds of finds melted out of the ice in Innlandet County that year. The high mountains of Innlandet have seen repeated episodes of melting of old ice in 2007, 2009, 2010, 2011, 2013, 2014, 2018 and 2019. More than 3500 archaeological finds have now been recovered in Innlandet County alone, making the region the most finds-rich area for glacier archaeology globally with more than half the finds worldwide. Like Yukon, we have a long-term funded program for rescuing the finds from the ice.
Oppdal has also seen melting and many new finds. Recently, finds have also started to appear in other mountain regions in southern Norway.
The nature of the melt
Having worked in the field of glacial archaeology for more than a decade, we now understand the mechanisms of melting better. The ice patches, where we discover most of our finds, are clearly on a downward trajectory. This does not mean, however, that they get smaller every year. Their size goes up and down, but the trend is clearly down, just like the Arctic sea ice (more on the nature of ice patches here).
It is the same in other parts of the world. Our Yukon colleagues had a quiet period in the first part of the 2010s, befiore they were hit with a major melt in 2016. It is clearly an advantage to have a long-term funded program, allowing for the ups and downs in the melting situation. Short-term projects may (and have) hit a quiet period with little or no melting of old ice, where little work can be done, making it difficult to get further funding.
In 2019, the world of ice patch archaeology was extended to include Mongolia, when an American-led team made the first discoveries in the Altay Mountains.
The future of glacial archaeology
That was a short history of glacial archaeology, from the small beginnings in the early 20th century to the find explosion from 1997 onwards. What lies ahead? Well, the mountain ice will continue to melt. It is hardly a bold prediction to forecast that more spectacular finds will be made in the regions where fieldwork is already taking place.
There should also be other places where archaeological discoveries are still waiting to be made, most notably perhaps in the Himalayas, where old caravan routes crossed the ice fields. At the moment, the finds from the Himalayas are limited to missing mountaineers, but that is likely to change.
The prospect of making new discoveries from the retreating ice in the coming years is exiting and sad at the same time. As glacial archaeoogists, there is little we can do to stop global warming and ice melt. Our priority is to record the history of a melting world. The task is to rescue the artefacts, preserve them for the future and try to unlock their story about the past. As our recent paper on the lost mountain pass at Lendbreen showed, the story told by the finds is very relevant to the world we are living in today. Climate change was a challenge in the past as well.
