Heavenly Peak
“The island’s average rainfall, which is much greater in the mountain areas facing the north and east, is 1,960 millimetres (77.2 in) per year. Where the higher elevations of the Blue Mountains catch the rain from the moisture-laden winds, rainfall exceeds 5,080 millimetres (200 in) per year with some areas have totals of over 7,620 millimetres (300 in). This climatic diversity has enabled the high rainfall that feeds the lush vegetation, which includes towering trees and over 500 species of flowering plants, of which half are found nowhere else on earth.”
