They are of three kinds: straight lines, some several kilometres long, that radiate from about 62 low hills and rises the surveyors call line centres; cleared trapezoids and rectangles; and figures, from the giant hummingbird, monkey and spider 50 to 300 m long to small figures of a few metres cut into hillsides⁠[[1]]⁠[[2]]. All were made the same way, by lifting the dark, iron-stained surface stones and piling them at the edges to expose the paler ground, a technique that needs no more than cords, stakes and labour and that survives because the pampa is one of the driest places on earth⁠[[3]]. The makers are known from the pottery left on the lines and from excavations in the valleys. The hillside figures belong to the Paracas culture of the later first millennium BC; the pampa lines and the famous animal figures belong to the Nasca culture, dated by radiocarbon at Palpa to about 200 BC to AD 650, with some lines reused and added later⁠[[4]]⁠[[5]]. The 1980s survey led by Anthony Aveni mapped the line centres and showed that the lines were walked, link to one another and to water courses, and do not point to the sky in any pattern beyond chance⁠[[1]]⁠[[6]]. What the lines were for is the question that remains. In 2024 Masato Sakai's team at Yamagata University, with IBM, used an AI detector on high-resolution imagery and then field-checked candidates, finding 303 new figurative geoglyphs in six months and nearly doubling the known total⁠[[2]]. The enlarged catalogue let them show that the small relief-type figures, mostly humans, domesticated animals and severed heads, lie beside footpaths and were meant to be seen by people walking, while the giant line-type figures, mostly wild animals, lie beside the network of ceremonial lines and trapezoids and were made at community scale⁠[[2]]. A further 248 geoglyphs were announced in August 2025⁠[[7]]. Of the 4 questions on this site, 2 are answered.

Removing the stones leaves a line visible for centuries in the absence of rain and wind erosion⁠[[3]]. The lines are best seen from the air, which drove the earliest speculation, but the surveys show every figure and line can be laid out from the ground with simple methods and that the lines were made to be walked: they are bordered by stone heaps, worn paths run along them, and a 4.4 km labyrinth recorded by Ruggles and Saunders can only be understood by following it⁠[[1]]⁠[[8]].

CC BY-SA 4.0[Artifact ](https://mysteriesdept.com/mysteries/nazca-lines/artifacts/ART0CT6XKXJ2HTG/the-hummingbird-geoglyph) The Nasca lived in the valleys that cut the desert, where water runs only part of the year. They built puquios, underground aqueducts with spiral entrances, to reach groundwater; many survive in use⁠[[9]]. Their ceremonial centre, Cahuachi, a complex of adobe mounds on the south bank of the Nazca river, faces the pampa and is reached by lines from it⁠[[10]]. The World Heritage site, inscribed in 1994, covers the pampa and the Palpa valleys⁠[[11]]. **Map of the area** [Open the full map](https://mysteriesdept.com/mysteries/nazca-lines/map) [Area][Region] [+][−] 1 **Cahuachi** Ceremonial centre Within 100 m 2 **Nazca pampa (Pampa de San José)** Desert plateau Within 10 km 3 **Palpa valleys** Valley system Within 10 km MappedA regionNatural Earth ### Timeline **Timeline** Squeezed where little happened. Each mark is a published claim, by how it stands:AcceptedMost likelyStill possibleDisputedRuled out ## What was found Aveni's teams mapped 62 line centres from which some 800 straight lines radiate, recorded the pottery on them, and walked them; the lines link centres to one another and tend to run toward water courses and along the axes of the valleys⁠[[1]]⁠[[3]]. Ruggles tested the azimuths of the radial lines against the sun, moon and stars and found no significant pattern beyond a weak solstitial tendency⁠[[6]]. Silverman and Browne dated the Ingenio valley lines by the pottery on them to the Nasca phases, with Paracas hillside figures earlier⁠[[4]]. At Palpa, the German Archaeological Institute's project dated the sequence by AMS radiocarbon and documented the hillside figures with photogrammetry⁠[[5]]. Geophysical and geochemical measurements across lines and off them at Nasca and Palpa found no systematic difference in the ground beneath, which tells against the reading that the lines mark faults or buried water courses⁠[[12]]. Sakai's group trained a deep-learning model on the known relief-type figures, which are small and hard to see, and used it to rank the whole pampa for field survey; four new figures were confirmed in 2023 and 303 in 2024, bringing the figurative total to 733⁠[[13]]⁠[[2]]. Of the relief-type figures, 81.6 per cent show humans or things humans had modified, such as llamas and trophy heads, and they sit on average 43 m from ancient trails; of the giant line-type figures, 64 per cent show wild animals, and they sit on average 34 m from the ceremonial line network⁠[[2]]. By August 2025 the team had added 248 more, including 41 human figures, 31 decapitation scenes and 21 llamas, arranged by theme along small paths, for a figurative total of 893⁠[[7]]. ## What is known The method is settled by the surveys and by the stone heaps and paths; nothing about the lines requires technology beyond what the Nasca had⁠[[3]]⁠[[1]]. The date is settled to the Paracas and Nasca periods by the associated pottery and the Palpa radiocarbon sequence⁠[[4]]⁠[[5]]. The lines were walked, and the straight lines connect centres, the valleys and water⁠[[1]]⁠[[8]]. Astronomical alignment is not a general property of the lines⁠[[6]]. The pampa's figures are now catalogued at a scale that permits statistics, and the 2024 study is the first to show a difference in motif and placement between small and giant figures that bears on who made them and for whom⁠[[2]]. The site is under pressure from informal mining and from traffic; in June 2025 the Peruvian government cut the 5,600 km² protected zone by 42 per cent to open permits and reversed the cut within days after objection⁠[[14]]. ## The explanations The astronomical calendar, Maria Reiche's reading, holds that lines point to solstice and other risings and that figures are constellations. Hawkins's 1968 test and Ruggles's statistics found no more alignments than chance; the reading survives only for a handful of lines⁠[[15]]⁠[[6]]. The water reading comes in two forms. One, from the 1980s survey, is that the lines were made and walked in rites concerned with water and fertility, since they run to and along water courses and the Nasca lived at the limit of irrigation; it is consistent with the line centres, the paths and the puquios⁠[[1]]⁠[[9]]. The other, that lines physically mark aquifers or faults below, was tested by geophysics and not supported⁠[[12]]. The ritual-path reading, that lines and trapezoids were processional routes, with Cahuachi as the pilgrimage destination, fits the paths, the labyrinth and the position of the giant figures beside the line network⁠[[10]]⁠[[8]]⁠[[2]]. The 2024 study adds a second scale: small figures beside footpaths were for individuals or small groups passing, and their motifs, humans, llamas and trophy heads, differ from the wild animals of the community-scale figures⁠[[2]].

Excavation at line centres and along trapezoids for offerings, pottery and dated organic matter would tie individual lines to phases and to events⁠[[3]]. Publication of the 2025 finds with coordinates and dates, and an open catalogue of all geoglyphs, would let others test the claims⁠[[7]]. ## Questions 2 of 4 questions are answered. **Key questions**
