Geography
Pedra Branca is an erosional remnant of the Tasmanian mainland. It is approximately 270 metres (885 ft) long, 100 metres (330 ft) wide, and 60 metres (200 ft) high. This is small enough to provide an example of an outcrop that lies on the border between being a rock or islet and an island. The island is estimated to have separated from the mainland at least 15,000 years ago.
The geology features three breccia cones of dolerite and sandstone.

Famous quotes containing the word geography:
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
“Yet America is a poem in our eyes; its ample geography dazzles the imagination, and it will not wait long for metres.”
—Ralph Waldo Emerson (1803–1882)
“Ktaadn, near which we were to pass the next day, is said to mean “Highest Land.” So much geography is there in their names.”
—Henry David Thoreau (1817–1862)
