Phaq'u Q'awa, Mountain summit in Sajama National Park, Bolivia

Phaq'u Q'awa is a mountain in the Cordillera Occidental of the Andes, reaching about 5,380 metres. It stands in the Oruro Department, Sajama Province, in the west of the Curahuara de Carangas Municipality, northwest of the extinct Sajama volcano and south of Qullqi Warani. The river Junt'uma K'uchu rises on its northern side and flows southeast as a right affluent of the Sajama River.

The name Phaq'u Q'awa comes from Aymara, combining phaq'u (light brown, reddish) and q'awa (little river, ravine), meaning "brown brook" or "brown ravine". Colonial and later cartography recorded the peak under Hispanicized spellings such as Pacocahua and Pajojañua. It lies in the Cordillera Occidental, in the west of Curahuara de Carangas Municipality, Sajama Province, Oruro Department, northwest of the extinct Sajama volcano and south of Qullqi Warani.

The name comes from the Aymara language, where phaq'u describes the light brown and reddish tones visible on the mountainside. The term q'awa refers to the small streams and crevices you can see carved into the rocky slopes.
