Object description

Glass House Mountains National Park is a heritage-listed national park at Glass House Mountains, Sunshine Coast Region, Queensland, Australia. It is also known as Beerburrum Forest Reserve 1. It is 70 km north of Brisbane and consists of a flat plain punctuated by rhyolite and trachyte volcanic plugs, the cores of extinct volcanoes that formed 27 million to 26 million years ago. The mountains would once have had pyroclastic exteriors, but these have eroded away.
