Ice Age Discovery
A Mammoth Discovery
Snowmass Village has developed “mammoth fever” ever since the exciting discovery of juvenile Columbian mammoth bones made while bulldozer operator Jesse Steele was working on the expansion of Ziegler Reservoir in October, 2010.

Soon after, the excavation went into full swing when a team from The Denver Museum of Nature & Science arrived, and along with hundreds of local volunteers, discovered a treasure trove of Ice Age fossils.

Scientists are now using the findings as an opportunity to learn more about the Ice Age history of the Rocky Mountains.

Facts on the Find

  • The Ziegler site has yielded the largest collection of Mastodon bones from a single site anywhere, and is likely the best high elevation Ice Age site in the world. 
  • Initial radiocarbon dating indicates that the site is more than 45,000 years old. Geologists estimate it could be as old as 130,000 to 150,000 years. 
  • In total, 4,826 bones were pulled from the site in 2011 
  • Seven species of large mammals and 19 types of smaller animals were identified.
