"Mosquito nets here are useless - better to use barbwire and sentries" - Fall expedition, 1936 Water is the lifeblood of any ecosystem, and nowhere is this more evident than on Skull Island. High rainfall for much of the year ensures that a constant flow of water works its way across, into, and under the land. This constant flow sculpts the landforms, carves deep gullies, and levels the grasslands. It fills holes to create pools and murky swamps and feeds the ravenous jungle that swathes most of the island. It defines and sustains much of the land’s geography and feeds all of its inhabitants.
