Nature
Rainmaker Mountain, near Pago Pago on Tutuila in American Samoa, is a volcanic landmark known for trapping rain clouds and helping make Pago Pago the wettest harbor, with about 200 inches of rain a year on the mountain. Its three-pronged summit and protected upper slopes support montane rainforest and scrub, leading to its designation as a National Natural Landmark in 1972. Geologically, it is a quartz trachyte volcanic plug tied to the history of the Pago Volcano. Biologically, it shelters rare endemic plants and seabirds, including recently confirmed breeding activity of the rare Tahiti Petrel on Tutuila.
