Guitarrero Cave has evidence of human life during the years between, 10,000–12,500 years ago. Above all that, there were series of Archaic period with campfires, dated between 10,500 years ago, and 9,000 years ago. Wood, bone, antler, and fiber cordage, and other were artifacts that recovered from the level, as well as willow leaf, tanged, lanceolate, and concave base Ichuna/Arcata projectile points. A single grinding slab and a bone flesher were also recovered from this part of the area. Levels were included in the Early and Middle Horizon occupations, cist tombs, and wall paintings between about the 1000 BC–AD 1000.
A discovery took place in 1960s, where the site has absolutely a preservation. Remarkably, textiles, wood and leather tools, and basketry have been preserved at this site. Some of the evidence of early domesticated beans Phaseolus, chili, corn and other cultivars have been argued for Guitarrero.
Fiberwork founded in the cave dates back over ten-thousand years – the earliest found in South America. The cave held utilitarian containers made by twisting, looping, and knotting plant fibers.
