A mastodon in Sequim? That’s just one of the highlights you’ll learn about at this regional natural and cultural history museum. View rotating collections and art exhibits and check out the Dungeness Schoolhouse, built in 1892. For researchers interested in doing a little digging, administrative offices, artifact storage, photo archives and the Whatton Research Library are open by appointment. Stop in at the Second Chance consignment store. Your purchases support museum programs and services.
