Melting ice patches in Canada's Yukon are giving up ancient hunting tools, some as old as 9,000 years, that have been locked in frozen ground since prehistoric hunters dropped or lost them chasing caribou. The film follows archaeologists racing to recover these artifacts, from wooden dart shafts to a 4,300-year-old find that anchors the episode, before they degrade in open air or are lost to erosion once the ice that preserved them is gone. Researchers examine each new object as a fragment of a much larger puzzle: who were the people who hunted these mountain slopes, how did their technology change across thousands of years, and what does the timing of these discoveries say about the pace of climate change in the north. Interviews with the scientists doing the fieldwork sit alongside footage of the ice patches themselves, ground that is retreating fast enough to be reshaping the archaeological record in real time. The finds keep surfacing faster than they can be studied, tools older than most written history unearthed by a warming world.
