Rainmaker Mountain

  (Redirected from Mount Pioa)

Rainmaker Mountain (also known as Mount Pioa[1][2]) is the name of a mountain located near Pago Pago, American Samoa on Tutuila Island. Rainmaker Mountain traps rain clouds and gives Pago Pago the highest annual rainfall of any harbor in the world.[3][4][5] The average annual rainfall on the mountain is around 200 inches (5 m).[6] It has a three-pronged summit. Rainmaker Mountain and its base were designated a National Natural Landmark in 1972 due to the slopes’ tropical vegetation.[7][8]

Rainmaker Mountain is one of several giant volcanic mountains that created Tutuila Island. It dominates the scene from nearly every point in Pago Pago Harbor. It compromises three mountain peaks: North Pioa, South Pioa, and Sinapioa. The peaks range in elevation from 1,619-1,718 feet. The 170-acre designated landmark area occurs above the 800-feet contour line. Several endemic species are only present here and on Matafao Peak, the highest point on Tutuila.[9]

Rainmaker Mountain, which is an important site in Samoan legends and lores, is also geologically important as an example of a volcanic plug (quartz trachyte). The upper slopes are montane rainforest and the crest is montane scrub. [10]

The mountain is a volcanic feature known as a trachyte plug. This means that it is a volcanic intrusion made of extrusive igneous rocks having alkali feldspar and minor mafic minerals as the main components and a fine-grained, generally porphyritic texture.

One can get a closeup view of the mountain by driving up Rainmaker Pass.[11]

Rainmaker Hotel was a hotel at the port entrance under the mountain.[12]
