Piki Mach'ay

Piki Mach'ay (Quechua piki flea, mach'ay cave,^[2] "flea cave", also spelled Pikimachay, Piquimachay, where machay means "drunkenness", "to get drunk" or "a spindle packed with thread")^[1][2] is an archaeological site in the Ayacucho Valley of Peru. Radiocarbon dates from this cave give a human presence ranging from 22,200 to 14,700 years ago,^[3] but this evidence has been disputed and a more conservative date 12,000 years BCE seems possible.^[4]
