A series of volcanic plugs created about 26 million years ago and now exposed by erosion of the surrounding softer materials. The rocks are trachite and rhyolite.

The Glasshouse Mountains were named by James Cook, captain of the ship bearing the first Europeans to see the mountains. He observed them from the ocean to the east and named them for their resemblance to the glass-making kilns of his native Yorkshire in England.
Very nice gallery. I like how they names the mountains after their dingo and the father of mountains. The plants are interesting, especially all the different species of Banksia.
