Our Visitors Say It Best…

leaf“The Mammoth Site is not just a window into the past—it’s as close to being a true time machine as you’ll find, with some of the best ice-age fossils on the planet on permanent display.”
Ross MacPhee,
Division of Vertebrate Zoology,
American Museum of Natural History, New York City

leaf“The students examined fossil and non-fossil examples then made their own fossil imprints. The students had great fun and loved the activity.”
Savage Branch Library
Howard County, MD

leaf“We used the Kindergarten through 5th grade kits for an evening program and presentation. The parents were very impressed and the teachers loved the completeness of the lesson plans. They were easy to work with also during class time.”
