Spermophilus parryii Arctic Ground Squirrel Arktischer Ziesel When Yukon placer miners remove frozen organic "muck" to get to the underlying gold-bearing gravel, they sometimes expose fossils of ice age animals. Few discoveries are more interesting than the nests of ancient Arctic Ground Squirrels. Radiocarbon dates and other geological dating methods suggest that some of the nests are more than 90,000 years old! Blackstone Uplands, Dempster Highway, Yukon, Canada |
