Name

Phaq'u Q'awa derives from Aymara language terms phaq'u, paqu, or p'aqu meaning the color light brown, reddish, fair-haired, or dark chestnut, and q'awa meaning little river, ditch, crevice, fissure, or gap in the earth, the name thus meaning "brown brook" or "brown ravine". The Hispanicized spelling is Pacocahua or Pajojañua.
