Waterfalls are plentiful along Acheron Passage, especially south of Wet Jacket Arms. They are sourced by two mountains on the port side of your ship: Mount Forster (3,700 feet) and Mount Hodges (3419 feet). There are at least a hundred more falls in nearby Dusky Sound. These cascades are especially bountiful after a heavy rainfall. And there is no shortage of precipitation around here. Typically, it rains up to 300 inches during about 200 days a year. The tallest waterfall within Fiordland is Sutherland Falls near Milford Sound with an amazing, three-level drop of 1,900 feet.
