Kate and the Wyoming fossil fiasco

the long version

"When Kate's former schoolteacher becomes a curator at a small science museum, she is invited to help out. But an accidentally spilled drink leads Kate and McKenzie on a quick quest to Stone's Throw Quarry fossil camp. Disintegrating fossil plates-- brown sugar-- lots and lots of brown sugar-- A suspicious quarry staff member-- A door marked 'Private'-- Will the girls' suspicions prove false? Or can the Camp Club Girls dig deep enough to unearth the culprit behind the phony fossils?"--P. [4] of cover.
