Ancient artifacts revealed as northern ice patches melt

Global warming continues to reveal ancient artifacts buried under ice patches for thousands of years. Some of the latest finds are in the Mackenzie Mountains in the arctic regions of North America.

Ice patch archeology is a recent phenomenon that began in Yukon. In 1997, sheep hunters discovered a 4,300-year-old dart shaft in caribou dung that had become exposed as the ice receded. Scientists who investigated the site found layers of caribou dung buried between annual deposits of ice.
