The finds are truly remarkable: iron arrowheads dating back 1,500 years, tunics from the Iron Age, and even the remains of a wooden ski complete with leather binding left behind sometime in the year 700. Some of the oldest objects were dropped more than 6,000 years ago. The catalyst behind the sudden emergence of these ancient relics is climate change, with lower winter precipitation and warmer summers dramatically reducing the alpine ice that acts as a time capsule for lost treasures. "The ice is a time machine," Lars Pilö, an archaeologist who works for the Oppland County council told Archaeology in 2013. "When you’re really lucky, the artifacts are exposed for the first time since they were lost." A ski with leather binding recovered from an ice patch in the Norwegian mountains. Analysis later determined that the artifact dates back to the year 700.

These isolated non-moving accumulations of ice and snow are significant to the archeological record because of their extreme stability, with many containing layers of seasonal snowpack dating back thousands of years. Sections of ice in the Juvfonne snow patch in Jotunheimen, Norway, are an astounding 7,600 years old, according to a 2017 study.

In the summer, reindeer herds often crowd together on the islands of snow and ice to escape pesky, biting botflies, which have a strong aversion to the cooler temperatures. In the past, hunters would follow, losing or forgetting precious equipment along the way that was later buried and preserved in the winter snows. Some items, such as the 1,600-year-old knife shown in the video below, look as if they were lost only a few decades ago. Because ice patches in the past have contracted and expanded due to temperature shifts, many of the objects recovered have likely one time or another been exposed and then reburied by snow and ice. They also have a tendency to be carried by meltwater. As explained on the Secrets of the Ice Facebook page, the 2,600-year-old arrows shown in the image below were washed downslope far from the place they were originally lost. Arrows discovered in the scree of an ice patch were later determined to date back to 600 B.C.

These artifacts are generally exceptionally preserved, with organic materials such as leather and fabric still present. It's also an indication of the severity of anthropogenic global warming, with certain ice patches in Norway estimated to have retreated to levels last seen during the Stone Age. “It’s very impressive when you can say this melting ice is 5,000 years old, and this is the only moment in the last 7,000 years that the ice has been retreating,” Albert Hafner, an archaeologist at the University of Bernsays Hafner, told Archaeology. “Ice is the most emotional way to show climate change.” The preserved remains of a 3400-year-old hide shoe discovered on an ice patch in 2006. Over the last 30 years, some 2,000 artifacts have been recovered from Norway's melting ice fields.

It is incredibly valuable and it’s on fire now,” George Hambrecht, an anthropologist at the University of Maryland, College Park, told New Scientist. Archaeologists are in a race against time to discover and preserve ancient artifacts exposed to the elements.

The reality, however, is that field work can sometimes be laborious and uncomfortable, with every day at the mercy of Mother Nature's fickle moods. That said, the Oppland County Council did accept volunteers last spring and it's possible, especially with so many finds emerging from the ice each year, that others may be called upon to assist. "We may not find much (or we could strike the jackpot, who knows)," Lars Pilø wrote last April in the Secrets blog. "It all depends on the melting conditions, and they develop over the summer and during fieldwork. If we are unlucky, the scenery and the team spirit make up for the lack of finds."
