Educational programs include:

Jr Paleontology Program – designed for ages 4-12 allows children to become a Junior Paleontologist while they dig for fossil replicas. A guardian must accompany children and is required to purchase admission to the Mammoth Site.

Family Dig Program – designed for the whole family. In this class, families will work together to excavate fossils in a simulated dig site. Lead by a qualified guide, participants will learn how paleontologists discover and excavate a site, using the same tools we use in the Bonebed.

Atlatl Family Throw – This class is for participants 8 and older. Weather permitting, this class is held 7 days a week at The Mammoth Site from June 1st through August 15th. Sessions are held daily at 10 am and 3 pm. Closed-toe shoes are required. The Atlatl Family Throw allows families to test their skills with hunting technology first developed during the Ice Age. Participants in this program will learn how atlatls work, how they are used, and their history. Participants will also get to try atlatls out while conducting some Citizen Science!

Regular Museum admission is not included in the Atlatl Family Throw fee.
