Snowmass Fossil Dig At Ziegler Reservoir Ends; Brings Ice Age Back To Denver

The largest fossil excavation project just wrapped up at the now infamous Ziegler Reservoir near Snowmass Village. The excavation quickly unearthed a grand total of 4,826 bones over a seven week period, becoming the most significant fossil site in Colorado history and freezing a geographic chuck of the Ice Age in time.

Finds from the site will make their way to the Denver Museum of Nature and Science to undergo a slow-drying process in an in-house lab meant to preserve and protect the fossils, which may take many months.

From the Snowmastodon Project press release:

  • 74 large specimens in plaster jackets
  • 49 tusks (29 upper jaw tusks and 20 lower jaw tusks)
  • 34 mandibles (jaws)
  • 23 skulls
  • 20 pelvises
  • 82 loose teeth
  • 125 logs and numerous samples of peat, wood, leaves, and rocks

Next week the museum will host the "Ice Age Spectacular" to celebrate their Ice Age findings and display them for the first time. There will also be several touchable fossils near the preparation laboratory where the museum will be slow-drying their major finds.

Fossils discovered at the site were voted unanimously by the Snowmass Water and Sanitation District to be donated to the museum.

The National Geographic Society plans to feature the Snowmass Ice Age-finds on PBS as part of a NOVA special airing on PBS next year.

Evening Lecture: Snow, Mud, and Mastodons
Thursday, September 8
7 p.m., $12 for members/$15 for nonmembers
They battled snow, sleet, rain, heat, and massive amounts of mud to pull thousands of Ice Age fossils out of the ground. Now Kirk Johnson and Ian Miller, PhDs, will share all the latest "dirt" as they offer updates on the new discoveries, show off some of the spectacular finds, and explain what this project means to science and to Colorado.

Exhibition: Mammoths & Mastodons: Titans of the Ice Age
Coming in Spring 2013
The Museum will host a touring exhibition from the Field Museum, featuring video installations, hands-on interactive displays, life-size models, fossil tusks and skulls--and even touchable teeth. The exhibition features a 42,000-year-old intact baby mammoth named Lyuba. Discovered in 2007 by a Siberian reindeer herder and his sons, Lyuba is by far the best-preserved mammoth specimen ever discovered.
