Piki Mach'ay (Quechua piki flea, mach'ay cave,[1][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 dating from this cave indicates a human presence ranging from 22,200 to 14,700 years ago,[3] but this evidence has been disputed and a more conservative date of 12,000 years BCE seems possible.[4]
Richard S. MacNeish was the first archaeologist to explore Piki Mach'ay.[5] Evidence of long-term human occupation has been found at the site, though that evidence still remains controversial.
The cave is part of the Ayacucho complex, a culture defined by several cave sites including Jaya Mach'ay ("pepper cave").[6]
