Pu'uka'oku is another record-setting waterfall -- this one found along the rugged coast of Moloka'i in the Hawaiian Islands. This thin ribbon of water is located on a cliff on the island's northeastern coastline, where it drops 2,755 feet (840 meters).

Like other waterfalls along this dramatic shoreline, Pu'uka'oku has carved a deep fissure into the porous volcanic basalt of the cliff face. This makes it harder to see than younger cascades, which haven't carved away as much of their beds. Tourists may be able to make out the falls from boats or helicopters led by experienced guides who know exactly where to look.

The coast of Moloka'i is a fearsome environment that sometimes produces a phenomenal sight. Powerful winds blowing up the cliff face loft the falls into the air, causing them to fan out into misty spray. The water literally takes flight on the howling wind, giving hardy viewers a glimpse of a truly rare natural phenomenon [source: Pavils].
