The Hot Pink Gorilla
A Keystone Science School Mystery

For as long as Keystone Science School has existed, the Hot Pink Gorilla (HPG) has been spotted roaming the hills of Keystone, Colorado. This elusive creature leaves behind curious evidence (handprints, banana peels, & scat) sparking endless scientific inquiry among our campers.

Each summer, young explorers take on the role of field researchers, using observation, hypothesis-building, and critical thinking to uncover clues about the HPG’s origins. Why is its fur pink? What is its connection to the legendary Grape Ape? And will anyone ever make direct contact?

Through immersive outdoor exploration, campers hone their investigative skills, follow the evidence, and embrace the wonder of the unknown—just like real scientists. The search for the Hot Pink Gorilla isn’t just a game; it’s a hands-on adventure in curiosity, discovery, and the spirit of Keystone Science School.
