In October 2010, a bulldozer operator working near a Colorado
ski area uncovered the tusk of a young female mammoth. Over the
next 10 months, the Denver Museum of Nature & Science conducted
its largest-ever fossil excavation, yielding a treasure trove of
well-preserved Ice Age fossils. Museum crews uncovered 5,000
bones of 41 kinds of Ice Age animals, including mammoths,
mastodons, ground sloths, camels, deer, horses, and giant bison.
The preserved series of Ice Age fossil ecosystems is one of
the most significant fossil discoveries ever made in Colorado. This
discovery at Ziegler Reservoir near Snowmass Village will change
forever our understanding of alpine life in the Ice Age.
