Ua Huka - Geography

Geography

The island is shaped approximately like a crescent, with its concave edge facing the south. The land area is approximately 83 km² (32 sq. mi.). The center of the island is a high plateau, deeply indented in places by narrow river valleys. The highest peak, Hitikau reaches an elevation of 857 m (2,812 ft). Much of the island's native plant cover, which outside the valleys consists primarily of dryland scrub, has been devastated by herds of feral goats and horses, which are estimated to number upwards of 3,000.

Ua Huka is a shield volcano that was emplaced between 2.2 and 2.4 million years ago. It is thought to have formed by a center of upwelling magma called the Marquesas hotspot.

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)

    At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.
    Derek Wall (b. 1965)

    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)
