Geomorphology and Landscape
The Capricorn and Bunker Cays form part of a distinct geomorphic province at the southern end of the Great Barrier Reef. The cays and their reefs lie on the western marginal shelf, and are separated from the mainland by the Curtis Channel. The cays are not generally visible from the mainland, although Masthead Island may be viewed from Mount Larcom on a clear day.
Geologically the cays are young, having developed during the Holocene period, they are mostly around 5000 years old. The sea level was much lower during the last Ice Age (at the end of the Pleistocene period) and the coastal plane on which today’s reefs and cays developed was completely exposed. Early in the Holocene (around 10,000 years ago) the sea level began to rise, until it stabilised at its present level around 6000 years ago. Once the sea level stabilised, it was possible for reef flats to expand and provide potential sites for the formation of cays.
One Tree Island is a Shingle cay and part of a Lagoonal Platform Reef:

Famous quotes containing the word landscape:
“Every landscape which is dreary enough has a certain beauty to my eyes, and in this instance its permanent qualities were enhanced by the weather. Everything told of the sea, even when we did not see its waste or hear its roar.”
—Henry David Thoreau (1817–1862)
