Bottlecap Volcano is a 1.2-million-year-old composite volcano located on Flagon Island just south of Hawaii. This Volcano is considered active since its last eruption was in 1967 with an eruption cycle of about about 90-110 years. The island was once home to Cold War government research, making the preserved ruins very interesting to look at. Sabrina, Peter, and Stephan are on vacation with Stephan's parents. The trio is thirsty for adventure, so let's hope that Bottlecap Volcano isn't more than they bargained for.
