A treasure trove of ancient weapons has emerged from melting ice patches in the Canadian Arctic, revealing hunting strategies thousands of years old. The weapons, which include a 2,400-year-old spear throwing tools, a 1000-year-old ground squirrel snare, and bows and arrows dating back 850 years, have been found high in the remote Mackenzie Mountains, a region where Mountain Boreal caribou abound in the summer months.
Dotted with ice patches resulting from accumulation of annual snow that, until recently, remained frozen all year, the mountains have been the caribous’ shelter for millennia. Seeking relief from the heat and annoying bugs, the animals huddle on the ice patches, becoming an easy target for hunters who recognized this behavior millennia ago.
Their tools buried deep beneath centuries of winter snow are now revealing how hunting strategies developed over thousands of years.
"We are talking of complete examples of ancient technology, including arrows with wooden shafts, feathers and sinew hafting. These artifacts are giving us an entirely new appreciation of how ancient hunting tools were made and used," Tom Andrews, an archaeologist with the Prince of Wales Northern Heritage Center in Yellowknife and lead researcher on the International Polar Year Ice Patch Study, told Discovery News.Ice patch archaeology began in 1997 when sheep hunters stumbled upon a 4,300-year-old dart shaft in caribou dung amid thawing ice patches in the southern Yukon.
"Following that discovery, we recovered more than 200 ancient hunting artifacts, with the oldest dating back more than 9,000 years," Greg Hare, the Yukon archaeologist who analyzed the original discovery, told Discovery News.
Thanks to global warming, Hare and colleagues also unearthed some 1,600 animal bones and mummified small mammals and birds that have been preserved in the ice for thousands of years.
"We began wondering if we had the same phenomenon here," Andrews said.
