When Kate's former schoolteacher becomes a curator at a small science museum, Kate gets invited to help out. While working in one of the exhibits, an accidental spilled drink lands on some of the fossil plates -- and the fossils begin to dissolve! Kate, along with help from McKenzie, is determined to get to the bottom of what's behind these fake fossils. The girls visit a quarry in Wyoming to dig a little deeper into the fossil fiasco...and soon are entrenched in suspicions about one of the quarry's staff members. Will their suspicions prove false? Or are the Camp Club Girls on the right track to solve yet another mystery?
