ThePicosa culture encapsulates theArchaic lifestyles of people from three locations with interconnected artifacts and lifestyles. It was named byCynthia Irwin-Williams in the 1960s for those areas: Pinto Basin (PI),Cochise tradition (CO) and San Pedro (SA), which all together is "Picosa".^[1]

The people in the dispersed locations in the American Southwest lived in similar housing, used similar burial practices and had similar lifestyles. The artifacts from the sites demonstrate similarity in the technology used and personal material goods. The Picosa culture has been found in the states ofCalifornia,Arizona,Utah,New Mexico andColorado. It was the predecessor to theOshara tradition.^[1]
