Ancient Tools Revealed by Melting Arctic Ice


Warming temperatures are melting patches of ice that have been in place for thousands of years in the mountains of the Canadian High Arctic and in turn revealing a treasure trove of ancient hunting tools.

Ice patches result from layers of annual snow that, until recently, remained frozen all year. As Earth's temperature has warmed in recent decades due to the accumulation of heat-trapping greenhouse gases in the atmosphere, some of the ice patches have begun to melt away, sometimes revealing ancient artifacts to the surprise of archaeologists.

Cool, maybe that's where LS has been lately... :)

If I understand the dating of the finds correctly, the irony is it appears it was warmer there then it is now anywhere between 850 and 4,300 years ago.

- 4,300-year-old dart shaft in caribou dung (now there's a story)
- 2,400-year-old spear throwing tools
- a 1000-year-old ground squirrel snare
- bows and arrows dating back 850 years

That's very true. And now it seems we may not only be about to relive their climate but also their culture.

Its cookery that blinds me, not science.
I have become that which I always despised and feared........Old !

My greatest wish, would be to own my own scrapyard.

Ha ha, I wish! Sounds like some really great finds. Perishable artifacts that typically wouldn't survive.

At times it likely was warmer, but also some of these artifacts would have just been lost in the snow packs as well while it was colder. For instance when the snow pack was present off target spears and arrows would have just penetrated the snow and end up lost in the snow packs until these recently melted.
