History
editThere is evidence that the island had prehistoric inhabitants. Graves, shell and bone tools, as well as stone markers indicate the presence of a permanent population at some point. The island is the topic of several oral traditions from Maré and the Île des Pines, the two closest inhabited islands. Speculation amongst the overseers of the Guano mining operation suggested that shipwreck or other castaways had also occupied the island.[1][2] British captain Butler is credited for discovery of the island in 1794 and he named it after his ship Walpole.[1]
From 1910 through 1936 guano was mined on the island and about 150,000 tonnes were exported to New Zealand.[1]
The island is only visited by scientific naturalist research missions.
Geography
editAs the easternmost island of the Loyalty Islands arc, Walpole is located 180 km (95 nmi) east of New Caledonia (168° 57' E, 22° 36' S). It is 4 km (2 1⁄2 mi) long north–south, and 0.5–1 km (5⁄16–5⁄8 mi) wide with an area of about 2.0 km2 (3⁄4 sq mi).
Walpole is a coral island of volcanic origin. During the last glaciation cycles, the island was submerged and rose several times, creating a coral capping. The island is bordered by eroding cliffs. On the eastern shore is a narrow plain.[1] The island has no source of surface fresh water.
